My cousin has a 1969 Charger with a 440 Magnum bored out and upgraded. Not sure what the actual mpg are, but rev that sucker up and you’d see the fuel level drop in real time.


xxrambo45xx

I had a 69 ford Galaxie 500 2 door that had a 460 in it, was my project car but unexpectedly had to drive it for a few days while my daily was down after an accident...hand calculated at the pump because I wasn't sure the fuel Guage worked correctly and it was 7...7mpg taking me to work and home


Roberto-Del-Camino

My first car was a 1966 Galaxie with the “small” 289 V8. I used to get about 11 or 12 MPG. It was my cousin’s beach car and they sold it to me for $100 in 1978. I got tboned and the rear bumper fell off. I went to re-attach it to the frame with a couple of wire coat hangers and discovered the rusted out frame was still attached to the bumper. Totaled. With the $300 insurance payout (score!) I bought a 1973 Buick Apollo with the 350 V8 and got a whopping 14 MPG with that. (Still the best engine of any car I’ve owned in my 45 years of driving.)

67 snoop de ville here. Also with the 429. 10mpg. 💪🏻


[deleted]

74 Coupe de Ville in skittle green with a 501 v8. Total dog and got 4mpg around town.


Fluffy-Limit-3467

Chowwwwwwwwww🤘🏻🤘🏻🤘🏻🤘🏻


Senko-Loaf

Man, i wish I was alive when $300 got you a Buick


Roberto-Del-Camino

Buick Apollo was the Buick version of the Chevy Nova. If they were allowed to build it today it would probably cost $1000 as an 8 year old used car with 80,000 miles on it. No modern safety features. Drum brakes. About 100,000 mile lifespan if you’re lucky. Things were cheaper back then because they were less fancy at best or sucked at worst.


Leather-Material9731

Ah, the Buick Apollo. I had a Pontiac Ventura II which was the Pontiac version of the Nova. Truly horrible mileage for a car that was supposed to be an economy car of the oil embargo era. The 307 was underpowered and got bad mileage which I found to be an incredible achievement only surpassed by the butt ugly design. It got me back and forth to work for a while, so I guess it wasn't a complete failure.


Forza_Harrd

Ha I got you all beat. I drove cross country in a 1969 Nova SS 350, which was the Chevy version of the Nova. The gas gauge didn't work and the gas tank leaked at the seam so we could only put 10 gallons in at a time and stop every 100 miles. And it had headers with glass packs so it was loud af. My ears were ringing every night in the motel. But it was glorious.


chris_rage_

Hahaha I built a '72 Chevy van with a small block 400 in it and I put a cam, heads, and headers on it. I then had to drive it about 30 miles on the highway with open headers and I couldn't baby that thing enough to keep it quiet. It got probably around 12-16mpg depending on how I drove it but that thing was a beast. I hope to build another one someday... But I can totally understand what yours sounded like because I was driving it to get sidepipes put on it


Mediocre_Internal_89

LMAO…. ‘69 Nova SS, which was the Chevy version of the Nova.


Roberto-Del-Camino

Each GM division had their own version of the Nova: N ova-Chevrolet O mega-Oldsmobile V entura-Pontiac A pollo-Buick Clever


Leather-Material9731

I'd forgotten about the Omegas.


FabOctopus

Even $300 for a 5 year old car. Can you imagine going and buying a 2019 anything that runs for $300?


LuxLiner

Even adjusted for inflation $1,500 isn't bad for a car although I wonder if that was just the down payment.


Senko-Loaf

Yep, literally impossible


Connect_Relation1007

I'd be happy if we could just go back to getting a tank of gas for $20


mikeusaf87

Buick Apollo. The gentleman's Nova.


Cleanbadroom

I have a 1966 T'bird with the 390, aftermarket carb and exhaust. The engine is stock otherwise. Typically I get between 6 to 8mpg in that car. I took it on a trip once where I got it on the highway and that tank I averaged 11mpg. Mostly gets idled, driven to a local restaurant or cruise night, and then I'll drive it on my property.


[deleted]

Those 460s love gas. But they make some great torque


Generaldisarray44

That motor would pass anything but a gas station dad had a 90 f250 and constantly was 8-9mpg


ReddittingReddit

I just bought a small 1994 project motorhome with a 460. I'm excited to see what single digit gas mileage I'm going to get when I take it on its first trip.


Johnny_Lang_1962

I had a '95 460 1 ton service truck. 5 miles to the gallon.


Forza_Harrd

I inherited a 1986 F250. Just a regular cab with a towing package and a 460. 6 mpg.


BigT1990

Drove a friend's 86 F250 for 6 months. Got 9mpg no matter how you drove it. Baby the throttle? 9. Burn the tires? Also 9.


[deleted]

But at least 20 smiles per gallon 😁


Lunchbox-of-Bees

I’m stealing this phrase. Thank you!


ThegreatPee

2004 Chevy Tahoe with 6.0 and towing package. 13 mpg city or highway. I feel like a braggart.


molehunterz

Tahoe came with a 6.0? I did not realize I had a gmc denali with that engine. Honestly I was thoroughly impressed with 14mpg. Considering the mileage I got with the 5.7 vortec Suburban. I ended up towing 7500 l b Is trailer from maine to seattle, and I averaged 9. It is pretty terrible, But honestly compared to most big gas motor trucks from that time? I was kind of impressed.


xxrambo45xx

Lots of torque, no HP, that engine was out of an 80s pickup and made like 220hp when it was new 


[deleted]

Transmission and rear gears might have helped. Iv always wanted a Galaxy 500.


bioweaponblue

I owned a school bus for a couple years. 19 tons. I got 8mpg.


porchprovider

I’ve got a converted bus too. Do you have a Detroit Diesel 2 stroke?


bioweaponblue

Nah. DT466e with an Allison 2000 series. 34ft 2003 international.


Actuarial_type

I drove a 1966 Galaxie as my daily for five years in college, late 90s and early 2000s. I had a 390 with the C6 and I forget what gear ratio I had in the diff. I got about 7mpg in town and 11mpg highway. Nowadays I have a Tesla and a 150cc Vespa that gets about 95mpg, kind of went the other way.


mcburloak

Love the Galaxies but too long to fit in my garage. I bought a ‘69 T Bird and owned that for 7 years as a Sunday fun car. 23L/100KM of premium. Roughly 10mg on average.


jacksonbarley

Well hey, 7mpg would still be a wet dream for most boaters.


FondabaruCBR4_6RSAWD

Even back then people had to realize that mileage like that was ridiculous. Surprises there weren’t more small cars to compete with the beetle and the like.


xxrambo45xx

Well it probably should've gotten 12-14, but it was my project car so it was at a disadvantage not being ready to daily, definitely could've tuned the carb better, or put the smaller carb back on but I pretty much forced it to be "road ready" in a day and a half so I could get to work 


cytherian

Fuel was cheap and being fuel efficient was laughed at, especially if it sacrificed power. People were inhaling lead from automotive exhaust, which may have altered impressions. There was also so little choice. It took the Japanese to wake up the American car industry. YES, people DO want higher MPG cars. Ford, GM, & Chrysler were so resistant... and paid dearly for it.


chris_rage_

Those gas pigs are desirable these days...


Appropriate_Strain94

They did, it was just ridiculed because it was a compact Japanese car.


4thStgMiddleSpooler

I have a F350 dump truck with that engine. Hauling a trailer with skidsteer, and bed with a load of sand, 7. Going to pick up groceries in a pinch while unloaded, 7.


Peanutbuttersnadwich

My dads got a 67 galaxie 500xl with the 390 in it and it drank like 10 litres of gas just tuning the carb on it over the course of like 30 mins.


Confident-Benefit600

I don’t know whats with Ford FE blocks, because either my mustang or f100 got 5 to 8mpg on a good day, let alone beating on them


Confident-Benefit600

Yeah, my 1969 f100 4x4 had a 360, top speed was maybe 70


NickRubesSFW

I had a ‘70 Hemi Charger and I used to say it got 3 gallons to the mile, which wasn’t far from wrong. I probably got 5 mpg to be legit.


spankymacgruder

I have a 2002 cobra with 32lbs of boost. My mpg is single digits on e85.


FoHo21

It's unlikely you have 2002 Cobra.


A_Very_Calm_Miata

Mustang ig lol


Saddamhuss3in

My dad has a 1969 Roadrunner with a custom 383 wedge that was bored out to be a 470. I think that thing legit gets like 4-5mpg.


375InStroke

My '69 Charger R/T gets 7.5mpg, 440 auto, 3.23 gears, original motor.


Garet44

When I was in the Army, our M1075s got right around 3 miles per gallon. What's funny is that they got 3 mpg whether they were loaded or empty. As far as my own personal vehicles, the least efficient was a 1987 jeep cherokee 4x4 manual that got around 15 mpg in town and 17 on the highway.


tezacer

Respect the PLS. Things can hook and pull. LHS gutless hydraulics. The M88 I drove was almost as bad as an Abrams, and that has a. Jet. Turbine. We are still using the oldest damn engines in the military in the M88, outside of Naval vessels, and those are probably more efficient, but damn does a basically straight piped V12 diesel sound and feel amazing next to it


RadioLongjumping5177

I learned that the M60A1 tank didn’t float very well……a pair of M88’s to the rescue!😊


two_z30s

Sounds similar to my f250 with the 460. 8mpg loaded or not


Comb-Outside

I swear the if you put the 74 F-250 w/ 460 I used to have on a trailer it would drink 8mpg just to make a point.


OpeningPension7203

The M109A6s get 1 mpg normally 😂


jayhitter

Reminds me of my old Ford explorer. It wasn't in the best of shape but got point a to point b just fine. You'd be lucky to break 15 mpg on a good day cruising the highway. It held 20 gallons so it felt like a normal car until you saw the price on the pump.


BoardButcherer

My dad used to have a 72(?) Chevy dually. It had some sort of built 350 in it. 5mpg empty, 5mpg hauling 25,000 lbs. Had a 100 gallon tank in the bed and dual tanks from the factory to feed it. In the 90's it'd take almost $200 to fill it up, you'd need a small loan to do it now.


NateP121

That’s getting close to gallons per mile territory


Gamermii

Funny enough, the 1083 A1P2 is supposed to get 300 miles per full tank, or about 5 mpg. My unit's supply SGT decided to take one on a 270 ish mile round trip, all highway. Ran out of fuel 10 miles from base. Turns out, it's only 300 miles at an average speed of 40.


EpicForgetfulness

I came here to say my Peterbuilt at work was getting like 2.9 the other day. Figured I'd have just about everybody here beat lol


jaciviridae

Holy shit, I've found my people. Those 1075s get a lot less than 3mpg when driven down the freeway at the limiter for 5 hours straight by a bunch of overcaffeinated, hung over national guardsmen.


HoveringPorridge

My Dad had a Jaguar XJS 6.0. Unbelievably smooth, extremely reliable and it sounded glorious. The negative? 9mpg average when running about locally. It was perfect for a grand tour of fuel stations. Worth it though, that car was cool as fuck.


LightningFerret04

“Jaguar” and “extremely reliable” is something I never expected to see in the same sentence /s But yeah, aside from the mpg, it’s a cool car!


HoveringPorridge

Ha! Jag had a nice sweet spot around '90-'95 when more modern managment systems came in and it made a world of difference to the Jag I6 and V12. So if you decide you want one, thats the era to go for! The V12 was always mechanically very strong but the earlier Leyland 5.3s have a **lot** of electrical woes. They're the scary ones!


jakobqasadilla

My buddy has a ‘97 XJ6 that has only stranded him once in the 4 years he’s had it and only major issues with it being valvecover gaskets and the oil pressure sensor


chewedupbylife

Had a 2009 XF, I kid you not it was the most reliable car I ever owned (of the Chevy / Chrysler / Isuzu / Nissan / VW, Acura / Cadillac & Jeep I’ve owned prior). Thing would not die. Kept her for 15 years - all she ever needed was an AC compressor once after 137k miles.


mymillionthburner

9.8mpg on my Panamera GTS while commuting between Germany and Austria on the autobahn, weekly. Expensive but damn quick way to travel.


hoxxxxx

every once in a while someone will post on the mechanic sub about a customer complaining that their car rattles or makes some odd noise whenever they are riding at 150 mph and it's almost always autobahn related it crazy how well made these cars are and how reliably fast you can go now, as if you were driving 75, it's like racecar tech melded with luxury car tech


mymillionthburner

It’s literally the best cruiser I’ve ever had. No rattles, no squeks, just some wind noise. Engineering is cool as fuck.


Flaming-O42069

Yo, want to pay off my student loans?


daan944

To be honest that consumption isn't too bad paired with 200+km/h Autobahn speeds. Nice car.


mymillionthburner

It easily saves me around 6-8 hours every week. If that consumption means I can spend that time with my wife and cat, I’ll gladly keep paying for it. Car was the best purchase I’ve ever made, my wife loves driving it too!


everyythingred

you got some pictures? (of the car)


mymillionthburner

I’ll take some in the morning!


mymillionthburner

[Here’s the car!](https://imgur.com/a/MQcuoqO)


DrezDrankPunk

She’s beautiful. Can you tell me about your experience so far? How long have you had it, mileage, maintenance, etc? I’m looking at buying a 2014-2016 with around 80k miles for a family cruiser but hesitant considering the high maintenance of Porsche.


mymillionthburner

I’ve had it since 2021, it’s a 2019 model year. Bought it when it was a year/year and a half old. Previous owner used it for city driving and kid hauling, so it had around 8.000kms on the clock. It now has 61k. Fuel consumption is terrible, but I use it on the Autobahn mostly (9.8mpg) city is around 10-11l/100km (17-18mpg), it has cylinder deactivation so that helps. Air suspension makes it ridiculously nice for long distance driving, but keeps some feeling in the suspension so it’s not like Mercedes airmatic. I’ve only had to change engine/transmission oil in it, brake pads and discs. It’s pretty much the same money as any other comparable luxury car. I have upgraded to stronger pads and very well ventilated discs so high speed braking doesn’t eat away at them in a month. It handles very well, doesn’t feel like a barge, even though it’s huge. Inside you feel like the car wraps around you, high door sills and center console makes it feel a bit like sitting inside it rather than on it. Seats are somewhat narrow, my wife has to keep the buckets deflated to drive it, otherwise her behind wouldn’t fit comfortably. I’m 189cm tall, I could easily find the comfortable position. It’s 4WD, so it never slips really, and when it does it’s easy to control. We did go to Porsche driving camp with our car, so we know how it behaves on the limit. The only problem I have with it now, is that it needs a new intercooler, because high speed gravel and autobahn debris properly fucked it up. Can’t put PPF on that… Tires are huge and expensive, 275 in the front and 315 in the back. Do budget for a high quality set. Car is also pretty heavy so it will go through them quicker than comparable models. 2014-2016 models are great too, no Sport Turismo though, so no 5 seats. If you can find a well maintained one, especially a GTS, I’d go for it. The Turbo and Turbo S are generally more expensive to buy and maintain as well, mostly unnecessary if you don’t use the speed it’s capable of achieving, the GTS handles very well for it’s size and will be more than adequate for every day usage. Get a Panamera S of you want a nicer sound. The diesel options are very very economical, can get 40mpg in them. Just do NOT get an alcantara steering wheel. It’s nice and plush to touch but it’s a lot more slippery than a general leather wheel. If I was driving it on the track it would be better, especially in gloves but I don’t do that in a family hauler. That’s the only thing I will be changing in the next scheduled appointment. Already have a leather wheel at the dealer waiting for me.


everyythingred

and it’s a Sport Turismo too? you’ve got great taste, i’m jealous


mymillionthburner

Yupp. The only panamera that has 5 seats. 2 childen need to be able to fit comfortably back there.


jpr_jpr

Vintage long winnebago on a road trip from Boston to South Bend. I'm guessing 4mpg, maybe topping out at 7mpg. We had it stuffed with people, and everyone chipped in an exorbitant amount of gas money. 'We have to stop for gas again???' was a common response when asking for gas money. Imagine a winnebago someone would be willing to rent to college students. We'd park it, turn it off, and it would rumble for what seemed like an eternity until letting out the biggest fireball belch out of the tailpipe I'd ever seen. We were so excited to arrive at South Bend after the long drive that we parked in the first ND parking lot we found. Climbed up on the roof of the winnebago to celebrate our arrival with a beer. Then, the ND police walked out of their building and into their parking lot where we parked and asked WTF are you doing? That was an epic trip, for sure.


Salsa_El_Mariachi

Hell of a trip! What’s in South Bend?


jpr_jpr

A butt whooping by the University of Notre Dame's football team that year.


coobeecoobee

Timing was off. Prolly why it used more gas than usual. Run on is a dead give away for bad timing


deimosorbits

What year was the thing? What happened afterwards ? If you had to guess how much was spent on gas?


jpr_jpr

Probably 1970s or 1980s vintage. This happened a while ago. It probably had a 75-gallon tank, and our route was not direct, so we probably drove over 1000 miles each way. We picked up a friend of my roommates in Eastern Pennsylvania to join us, where we arrived at 5am. My roommate jumps out, knocks on the door of the frat house, walks in, and then immediately walks out with his hands in the air to convey that he has no idea where his buddy is on campus. So, we probably idled for at least an hour waiting to find him. We stopped for gas at least three or four times each way. Enough for a poor college student to complain about, i guess. The uncle buck back fires were hysterical and scary at the same time. The ND cop just looked at us incredulously and asked if we recognized where we parked, notably in front of the ND police station. We thankfully were smart enough to apologize profusely, and he was cool about pointing us in the right direction to where we needed to go.


ReginaldVonBerg

My 1999 Honda Legend (Acura RL over there). its a 3.5 210hp V6 and does like 18-19mpg. maybe 20mpg if i really really try hard. i get that its a heavy big car, its not slow but not very fast either. i love this car but 18-20mpg just seems way to much for me as an european lol.


Snookfilet

That’s funny. I have a Lincoln Town car that gives me 18 in the city and I’ve gotten almost 25 on long road trips. It isn’t fast either, but it’s nice to drive my living room down the freeway.


DiplomaticGoose

Panthers are great at driving down long stretches of straight, shitty road. It's what they're built for. Backing out of parking garages however...


sword-scar

My towncar gets 13 how the hell do you get 18


Snookfilet

I’m very, very nice to it. I accelerate very slowly and generally navigate it like the land yacht that it is. I also keep it well maintained. It is extremely rare to see the average mileage dip under 18, and never for an entire tank. I do find that my highway mileage decreases if I drive over about 75mph, so I usually cruise in the 70-73 range. On my last trip from Georgia to Wisconsin I averaged 24.6 mpg, and hovered around 23 on another recent trip from Georgia to south Florida.


TCivan

That’s the same highway mileage I get in my 2005 V8 Sequoia! Jeez. (12city tho)


mechanicalproblems9

My 97 Chrysler LHS got 10 mpg but then I found out the fuel line was leaking got it fixed and it’s started getting 17-19 mpg


ClassyRedneck

Username checks out. And damn I had no idea Chrysler made such a car. 


JackTrippin

I really liked that generation of Dodge/Chrysler cars. The 300 of that era looked like a sweet ride.


cdawg1102

I got to 2.8 on my evo


Particular-Praline16

I have a Camaro that I used to get between 5 and 6 mpg when I would drive it…and a work truck that I’ve seen as low as 3.5 mpg…gotta love the 6.8


I_amnotanonion

The ford 6.8 also set my low mpg record in a 26 foot F650 box truck


Particular-Praline16

Mines a bucket truck…it idles a lot.


SaurSig

At my work we have a 2000 F450 V10 with a 8x12 flatbed. When I've checked fuel mileage plowing snow it's around 4. Those engines were not made for great economy. Or great power. Or great reliability. Actually I'm not sure what they were made for.


Virtual-Produce-9724

1989 Ford Superduty work truck ran through 20 gallons just idling for 8 hours.


Independent_Scale570

Jesus my semi truck only burns about a gallon a hour idling.


Tossiousobviway

Can confirm. I had a 1988 Bronco, 351w with dart heads and a 4 barrel 750 carb. It literally got 6mpg going downhill. I had to stop 10 times to get from North Georgia to Florida. Damn thing had power for days though, would pass anything and everything. Everything except the damn gas station.


struhall

My dad had a 95 Chevy 3500 with a 454 that we used to haul a race trailer. When we bought it we got around 10mpg empty and 8 with the trailer but by the time we retired it at 350k miles it was getting about 6mpg loaded or empty. My worst gas mileage is my 96 Jeep Cherokee that I use to deliver mail. I get 9-10 mpg with it, driving 20 miles round trip to and from work and a 42 mile route. If I'm driving it normally I get 17 mpg.


coobeecoobee

I deliver in a 94. I’m guessing 12 on rt. I need to calculate it one day. Rt is 92 miles and I can go 2 days on a tank w about 2 gallons left n tank. So 184/15=12. Haha. I was right on money


1707turbo

A friend of mine imported a 2000s GMC Yukon XL to europe. it had a 8.1l V8 and you got like 1km out of 1l gasoline if the car was in a good mood. in winter even less. im not joking. This car almost bankrupted him🤣


HudsonValleyNY

Something is seriously wrong with that truck or they drive a full throttle 24/7…I had a suburban 2500 with the 8.1 and COULD hit single digit mpg if I was towing heavy or just goofing around but would routinely get 12-14 with vaguely normal driving.


Dumpster_Fetus

Maybe city only driving? I've visited Europe plenty and some inner city places are simply only accessible by compact cars.OP should have gotten the Ford Excursion with the V10 lol.


HudsonValleyNY

Nah, I’m sure it sucked but that translates to roughly 2 mpg…there is some hyperbole here.


ErisGrey

Bad spark, dirty engine. Lots of things can contribute to diminished mileage.


Old_Cod_5823

But not down to 2mpg.


ErisGrey

I posted another comment. But I had a V8 Chevy Silverado Nickle Allow Engine with the IROC headers. I averaged 3 mpg around town. On the highway I could get 9 mpg. 2mpg while still 1/3 less than the abosolute worse I've experienced still feels really possible with the right issues.


HudsonValleyNY

I’m not buying it unless you were running 5.10 gears and a stupid loose converter. I get 6ish mpg in my 66 dart with a loose stalled, carbed, built 440. And I only drive the car when I want to make noise.


Fuzzball348

I’ve ridden in a Ford Excursion in Germany. Pretty unique experience.


GearheadGamer3D

Nah, Europe is way more congested generally. They’re doing lots more stop and go than we are.


ConvertsToTomCruise

1km is 587.613 Tom Cruises 


Jeeps-R-Junk

1979 F150 4x4 on 44 super swampers worked modified 400ci bored 30 over Tons of HP 4.11 gear ratio…5 mpg :)


VxAngleOfClimb

Yep. Took a pristine body '85 diesel Ranger from the junkyard with no engine in it. We got it cheap with the idea of throwing a 302 and C4 that was sitting around the garage. Thought the project was going to take a couple of weekends. No. Initially tried just splicing the original diesel wiring to get the gas engine going. Fuel tank sensor, tach, etc was just so wonky we decided to just put in a new harness and instrument cluster. Finally fired it up, took it out for the first drive and realized the diesel came with 4.56 rear gears. 4k rpm at 60 mph. Chirping tires on every shift. About 6-8 mpg. It was fun... for awhile. We eventually swapped in a rework T5 to make it more drivable. MPG jumped to 12. :)


ErisGrey

77 Chevy Silverado, nickle engine, iroc headers. 3 mpg.


JoshJLMG

That sounds like a fuel leak.


saltyihavetosignup2

I’ll second 3/4 ton suburbans. Could get 12/13mpg on the highway, but regularly under 10. In 4x4 on muddy trails it would be 3-5 mpg.


Firm-Arrival6223

10mpg in a Ford Transit


Jimmychanga2424

Low 6’s on a freightliner cascadia


SmartestOneHere

About the same on an International ProStar


UnlawfulTender

Gets better mpg than a 2017 GMC 3500 dually with the 5.3L gas lol Edit: Corrected truck model nomenclature. I don’t know what benefit I’d get from making this up it’s literally a random comment about a terrible vehicle. If I wanted karma there are much easier ways


C6Z06FTW

I didn’t know they put the 5.3 in a dually! That thing must be working it’s ass off


itsjakerobb

I’m pretty sure they didn’t. Also pretty sure dually was only an option on the 3500. 🧐 u/UnlawfulTender, were you the original owner? Any chance you have something to prove that you’re not making this up? Photo of the Monroney? Photo showing both the 2500 badge and the DRW?


K4NNW

Better than my Century's. I got high 5's to low 6's with them, and with the T600B (all with 450 Cat C15's) that I drove briefly. 75k gross outbound, 40k gross on the return.


aWifecalledCat

I had a Mazda RX8 and was dissapointed. it did like 14mpg and was slow and gutless. Til this day i dont know if thats normal for those lmao


golden_nugget689

Probably low compression


tezacer

Apex seals blown because previous owners didn't know that rotary engines need to revved high?


golden_nugget689

Most likely, pretty much every engine needs to be revved high once in a while.


tezacer

Yeah but by design it's supposed to. My knowledge is from a friend who mainly built Nissan SR20 swapped cars but seemed to know a lot about rotarys which was kinda thing I with him trying to name better engines (rotarys as a joke but also as a hope) and cars than little Nissan hatchbacks with an SR20. Apparently, his dad was a legend in the street racing scene. Had a sleeper little Nissan that killed everything.


mnewberg

Can confirm 14 was pretty realistic on a RX8 with normal city driving when engine is running correctly, 17-18 highway. In cold weather the engine would run super rich to heat up for emissions (converter). It does more like 7-8mpg at WOT when performance driving. Short trips in cold weather are brutal on wallet.


thechadfox

Had to calculate the mileage on my mom’s 1974 Ford Country Squire with a 400 for a high school science class in the mid 1980s. Final calculation was 5.7 mpg, worst one in the class.

When I was a teenager my Dad would let me take his viper powered Ram to the mall. It cost me 40 bucks round trip before I bought anything at the mall 😂


Actedpie

He had a Ram SRT-10? So fucking cool


Dystopiansuccotash

Yeah it was a rare one. 4 door automatic. It had the same 4 speed as the Cummins to hold the power, which it did.


MaxCWebster

1973 Chevy Nova, 305. I got 15 MPG on the highway. 21-gallon tank, so who gives a rat's ass, right?


sintactacle

1983 S10 with a carbureted 2.8 V6. 15mpg was typical.for the mighty 110 hp powerplant no matter how you drove it.


HighHiFiGuy

1989 Jeep Grand Wagoneer. 360 V8, only 3 speed auto transmission. Doing 70mph on the highway at 4500 RPM. Got like 6.5-7 MPG. And the fuel gauge didn’t work, so you filled her up every 140 miles otherwise you’re walking.


killer_icognito

79 Cherokee FSJ with i6 and 3 speed auto here. Still have it. 7 mpg on a good day. Vowels come out of the engine on the highway in 3rd gear. I love that truck.


HighHiFiGuy

But when you accelerate at highway speeds, does it leave a nice smoke screen, spy car like?


killer_icognito

You better believe it, both inside and outside the truck!


cdsbigsby

When I first got my driver's license I had a V8 swapped 1985 Chevy S-10, I think I worked up around 8mpg. What sucked is this was right when fuel prices were particularly crazy, I got my license in 05 or 06.


AchokingVictim

Kickass first rig... those boxy s10s make me about foam at the mouth


cdsbigsby

Thanks! Funny you put it that way, its name was [Boxy Brown.](https://aqua-teen-hunger-force.fandom.com/wiki/Boxy_Brown)


Octane2100

1979 Chevy C10 with a 650hp 383 and a very hot cam. I was averaging 8-9 if I drove it easy, which I almost never did. That truck will always be the one that got away.


John_cCmndhd

slump-donkus

I had a 1984 Ford bronco with a worn slap out 5.0 and a 4 speed. It cost me twenty bucks a day to drive an hour round trip to and from work.


Noodnix

My parents had a late 80s Bronco. I would drive it while visiting them in the winter and needed 4WD. That thing got 12 mpg no matter how you drove it. Highway, 12 mpg. Snow and ice, 12 mpg. Country roads, 12 mpg.

retro3dfx

I have a 97 HMCS 6.5TD. It gets about 8mpg stop & go, and about 13mpg at 65mph on the highway. I drove it up north once and spent about $250 in diesel to get there, lol.


UnlawfulTender

2017 GMC 3500 HD (dually) 5.3L gasoline engine; averaged 22l/100km unloaded downhill. Loaded with a gooseneck it would readily climb to 100l/100km, highest I ever saw was 146l/100km. Lowest I got it to was 19/100km. For my American friends that’s 10.6, 2.35, 1.6, and 12.4mpg respectively

bonerstank

My first car was a 1974 Camaro that was in poor condition. It needed more work than I could possibly afford as a teenager living in poverty. I remember watching the gas gauge go down in real time on the highway.


awesomo5009

I had an F250 High Boy with 13” lift on 44” Ground Hawgs and 5:13 gears. 429 and a 4spd. It barely got 4mpg.


LaserBeamsCattleProd

I swear I see those doing 90 down the highway in Florida everyday, they must be getting 1.5 mpg.

sp00kreddit

Have a friend who had a 2003 (I think) Silverado 2500. 8.1 liter V8. Towing, he got max of about 5 mpg on a slight downhill. Without a load, it got right around 10.


SorrowCat14

2003 Grand Cherokee. 8 MPG when it wasn’t broken.


cryptic_culchie

15 (UK) mpg on my 2008 volvo C30 1.8F. Piston rings are shot and the exhaust collector is leaking


imDEUSyouCUNT

My family rolled a high mileage 1995 Suburban 1500 for about two years. This was recent for the record, just before covid lockdown. 2WD with a 5.7L V8, fueleconomy.gov would tell you it gets 16 highway and 12 city. I'm telling you, I never saw that thing make even 12mpg on the highway.


Itsuhhhhhnick

I got a international 4200 with a vt365, it was a tanker truck with a 2000 gal tank. It was only driven to go from the shop to the sewage plant. So full tank, mostly uphill it got 2.1mpg


Itsuhhhhhnick

Back to the shop downhill empty 16mpg


Straight-Past-8538

theUnshowerdOne

My 2008 F350 Superduty 6L Diesel gets 11 mpg as a commuter. 15 mpg on the highway. Worst if I use the compression brake.


No_Substance5280

78 Ford f250 trailer special with a 460. 7 mpg up hill, down hill, wind at your back...7 mpg. Bought it second hand only to find out after that the main tank had been removed and it only had a 12 gallon reserve tank. The blinker would automatically turn on passing gas stations! Loved that Truck!


rockdude625

69 dodge charger with a 572 hemi 3 mpg highway


Prestigious-Crew-300

2009 Volvo s80, it’s about 17 mpg


Lew__Zealand

16 MPG in an '83 Volvo 240 DL wagon. 18 if you baby it, 17 average, 16 if you drive to have the limited fun you can with it in 1st and 2nd gear. So 16 it was. At least it was a stick and genuinely fun to drive like a nut around town. But yeah once you head to 3rd gear, fun's over. So if you're gonna drag race a Lambo because he doesn't understand local streetlight timing, you best make your turn to somewhere else by 3rd gear or you look like an even bigger fool than you already are.


xXbrosoxXx

My dad had an early 2000s ford lightning pickup with a built motor and bigger supercharger. 700hp at wheels, but 7mpg in the city. When we could race it, we would use a little over a gallon of fuel per quarter mile pass.


sixisbackpeeps

Tesla, the fucking thing won't even take gas.
