StrokerTA

So a buddy and I are having a little discussion about fuel mileage on a bolt on ls1 car.. Basic stuff, headers full exhaust, cai, gear(not a big stupid gear, just a 3.73)...
I think If you are driving it nicely you should be able to get 20 around town, he thinks 15mpg max..
What say the people of ls1tech.

My car gets 21-23 MPG depending on what time of the year it is, mostly highway. Most cars like mine seem to get better than that. Oh well.

You're auto and you have 214,000 miles. I'd say your mileage is pretty good.

I never got less than 18 in the winter letting it idle every morning. Generally it'll be over 20

All my LS1 cars get over 20mpg and 24 plus if i drive easy.

StrokerTA

Good deal, so I win the bet. I need to go buy one now and park my truck!

Better yet, put a LS1 in your truck!

Look at my sig. Worst milage i see is 20mpg and highway i have gotten 34mpg on cruise control flat highway driving this is due to the car being tuned to run leaner at low TPS %

I checked mine this morning. Driving spirited quite a bit, I got 20.4 mpg. Tunes work wonders. I'm camming it in a few weeks; I hope it stays decent.

StrokerTA

That seems really really low, I mean that's only 10mpg..

StrokerTA

That's what I'm looking for.. I wanna just have a full bolt on car, with suspension and a 12 bolt.. Then do an FLT stage 4 4l60e with a tight lock up yank converter.. Should be able to get great mileage and still run 12.0's..
