How much gas mileage do you get???
I was wondering how much gas mileage people were getting with different engine/trans/gear ratio combos. Tell your MPG and your drivetrain please.
My 97 Chevy 4wd extra cab gets 14.5 MPG with the 350/4l60e/3.42 ratio rears (I think). |
1969 C-10 short stepside, 350/350TH, 3.73 rear gears, 3700 lbs. I get 16 around town. Never checked the highway but the rear gear would hurt mileage for sure.
|
I reckon about equivalent of 14mpg.. 350SBC, TH400 and I think that's a stock rear end I'm running.
Bizzare thing is I get that ALL the time, towing 75mph everything!! is pretty weird....it only fluctuates by about 1MPG kinda weird I think... but there ya go.... |
Consistent 16 MPG, stock 230/3spd/3.73. Brian
|
502HO -400 turbo-3.07 Posi=10-11mpg highway (if you keep a "light" foot)
|
350/350 3.42 rear, dont know what kind of mileage :confused: , dont want to know :whine:
|
307/350 stock rear (3.73?) and a 2BB carb. I only get 12MPG. Hmmmm. Maybe I need to rebuild tha carb?
|
1.6L 4 speed manual trans with a 3.42 rear axle, getting 42 miles per gallon..... Whoops that was my chevette I use to have :lol: God I am missing that mileage now.
my 67 shorty with semi modified 355ci, 3 spped manual, 3.73 rear... 15mpg if your really sweet on the right petal.. |
my 4x4 s10 with a 2.8 v6, 5 speed, and 3.73 rear end gets about 24-26 when i am driving back and forth from school and i get between 20-22 when i am at home driving to work

uk72step, I had a 69 4wd blazer years ago and I put the torker 2 cam in and it got 11 MPG no matter what you did. Yes, it's wierd.

Thanks a ton for posting this thread. I wanted to see a similar thread, just didn't want to be the guy who started it :D
I've got a 68 step SWB w/L6 250 with a 1bbl carb and 3 on the tree. I get ~15-16MPG on the highway from what I can tell (65-70MPH). Not sure about city miles. The truck has plenty of 'pep', but I want to put something bigger in it. Not thinking as big as an LS1 or LT1 - more like the 4.8L V8 vortec engine that was in my '03 Sierra. I got 19-21 MPG highway with aftermarket intake and one of those hypertech programmer things. |
71 1 Ton Longhorn, 402, 700R4, 4:10 or 4:11 rear gear. 11MPG uphill, downhill, empty, full, towing or not. 11 MPG in town or highway..........but, man, can that thing pull my water trailer uphill! I get asked all the time what it has in it, cuz I pass everybody going up the hill.

1972 C20 4:10 dana 60 rear 700R4 trans can't remember tire size but they are at least 33" 400 hp 396 she gets about 5 mpg. 1986 K10 10 bolt 3:08 rears 700R4 trans stock 305 gets about 10 mpg...

355/350 buit with a dana 60 4:10 rear gear around 5-7 but thats with a 17 year old foot and duel 450 holleys :no: but during those couple miles she hauls ass!! :metal:
|
70 CST 383 TH350 GV overdrive 3:07 gears.....around 15 in town. Don't know on highway.
70 C20 454 TH400 - best so far 10.4 (WOW!) 49 CJ2a Jeep - 18-19 MPG 2002 VW TDI Beetle, 51 MPG highway, average 44 city. VW can make high mileage claims for their cars because you don't have to buy fuel for them when they are sitting in the service bay! :whine: |
My '71 with a 350/350 and 3:73's out back, it gets 12 no matter what I'm doing. The '97 pointiac grand prix GTP that I bought two weeks ago get around 20 in town and 26 on the highway, and its supercharged.

402/400th/373 posi
I don't think about it!!! |
'71 4x4 LWB, 350 V-8 with 2bbl Rottenchester, stump pullin' 4 speed and 4:11 gears. 31x10.50x15's, keep it at about 60 and can squeeze out 11+ on a good day. Push it to 70-75 and watch the gas needle move. :(

Man, after reading all of these posts the question should have been, gas mileage, whats that???
|
My 96 350/4l60e 3.42 31x10.50-15, 2wd...average 13-15 around town (depends on foot). Highway around 17-18 @ 70-75.
70 with the 250 3 speed, I think 3.73 probably around 11. But it is not driven much and it takes a while to get it untempermental (long warmups) |
