8.18 mpg city. Ouch

mrmtrtrnd

Wow 8 mpg, I'm getting more than twice that in city driving and averaging 21 combined city and highway. I think I would be looking for the cause of that problem.

Stop and go traffic?

How are you measuring the mpg it gets?

Keystring

My car is carb'd (I bought it that way) and I still get around 20-23 highway. 12-15 city.

I zero my trip odometer fill it up, then drive. Once I have driven for a few days, i refill. Simple.
Problem is 3.75 gears, 2800 rpm stall and a high horsepower 396LT1, and my right foot.

Does a high stall kill MPG?
Mine has 2800 stall Pete k. Torque converter. 3.07 gears.
can't keep the right foot of enough to get a real gauge of MPG.

City about 20/21. Highway @70mph: 30

gkrynick22

Not sure of the split, but I get a combined 18MPG. I think the 6 speed will improve that quite a bit.

C4orce2

I get about 18 mpg overall with my LS3 hot cam crate engine, 700r4 and 3.73 gears. I actually improved my mpg going with this new engine over my old LT1.

Overall I get 21, mix of highway, open road, and city driving, sometimes with my foot in it. Highway with ac on, cruise, I get 32.

dogfish246

I get 21 50/50 city and highway... I have gotten up to 27mpg on the highway and as low as 17mpg city... This is with an Automatic, 3.07, 1996 LT1...

I think I am going to find a C4 with a 6 speed, and use it to bring over the 396. The Vette has 144000 miles, so interior needs work and car needs paint. I think I can find a sweet Rubie 6 speed for less than 10k, and use mine as a parts car. I know if I changed gears it would help significantly , but the grin factor would be there. Besides, I would like to start rowing gears.
I get 17 highway.

My `87 gets around 26-27 mpg highway all day long. Thats with the 2:59 rear gears.

85corvettekws

My 85 with a 6 speed (not the 4+3) gets 27 highway and about 17 city. I'm pretty heavy with the gas though, L98 with nothin special here.

WW7

Im getting 26mph highway and 18mpg stop and go with my 383 stroker and 2:59 gears...WW

Charleston2012

How does it pull with the 2.59 gears? I was thinking 3.08's, but people recommended against, even though I have a 396 with 425 ft/lbs tq to the wheels and very flat torque curve.

WW7

Off the line not where I want it to be, but once it reaches 1600 rpms, its a rocket..Im thinking seriously about getting 3:07s for a better hole shot but I really hate to screw with this kind or gas mileage. Im not a racer anymore, Im a cruiser, but I still like my cars fast...D....WW

Itshakes

Just got back from Bloomington--240 miles - 22mpg. '96 LT4 4:10 gears lots of highway miles some "spirited".

wnafly

19.3-city, 28.5-highway with 93 octane, tried 91 octane and lost 2 mpg.

trying2seek

Overall 22 MPG, I have gotten as high as 30 MPG on the highway. 92 LT1
