If you are buying a V8 you can't be concerned about mileage cause it's not gonna be good. If it's that big a deal don't bother. I get 200 to a tank with a light foot combined city/highway.

Re: Gas Mileage of your LT1/LS1 car?

I realize it will not get good gas mileage like a 4 banger. But compared to my truck that i am driving now just about anything would be better than the 9mpg that it gets.
Current Daily Driver is a 1979 Chevy 1/2ton 4x4 with a 400hp 350

...or not... My LS1 gets better gas milage than a lot of 4 cyl's... Maybe if you're driving a modded to hell V8 which shouldn't be on the street anyway then you might get that kinda poor gas milage. But for an everyday driver, my V8 gets great milage for what it offers. I have to try hard to get under 300 miles per tank. (I have the 99+ 14.8)

Re: Gas Mileage of your LT1/LS1 car?

On my '95 basically M6 stock Z28 I average about 26mpg on the highway (between 70 and 80mph average) and about 17-21 in the city depending on traffic and my right foot, lol.

From my experience, with these cars you can eat a lot of gas in a hurry, but if you drive reasonably and do a lot a highway driving they can be pretty good actually. What kills me is having to pay the extra 20 cents or so for the premium! Thats why I keep an accord for a daily.
