06 SS. 5.3L k&n, magnaflow exhasut, diablo tune, some big ol rockford subs in the back. i average 18 all city driving. i have 39000 miles, and on the highway i saw 30-33 for 200 miles. that was awesome!!!!!! i drive offensively and generally keep it below 4000 rpm- unless someone comes along

 

I have a 2001 SS with the 3800 engine. Now everything is stock (hopefully that will change soon). I get about 21 in town and 30 highway. Im a pretty easy going driver cuz gas is so outrageous. There is 76,000 miles on it.

Do you have the standard Diablo tune or is it custom?

I get low 20's with a 60/40 mix of highway/city driving. I do stomp on it nearly everyday too for about a 1/4 mile.

 

Average 20 in the city and 31 on the highway.If I wanted a good gas millage car I would of gotten a volts wagon. My friend got one and now Putting a oil conversion in it. All of us have our choices, though I love my lucy. My friend gets 50 mpg, not bad for a 80's* car---considering 30mpg is a "break though" in GM today lmao. Though I like GM, they just are a "slow" lol. But anyway, "play around with the cute ones, then settle down later in life...around your 80s then have kids".
