My car is a 2000 m6 ss and has lt headers and dual exhaust, lid and cold air kit...plus a dyno tune.Since I got my headers and duals on plus the tune... if i drive my car all city i been only getting a little over 15 mpg. Before those mods i was gettin about 19 or 20 in city but i have been hitting on it a little more with the new exhaust. In my town you never get over 40 mph and there is lots of stop and go.

I would like to know what is wrong with my car as well then, because I get about 10 miles to the gallon shifting at 3K, and about 12-13 miles to the gallon shifting at 2200 rpms. This is pure city driving in which I only have 3 miles to go and have to stop at least 8 or 9 times. I shifted like a granny on this last tank of gas and still only got 185 miles out of the tank (no highway driving). Is that normal?

I change my oil every 2500 miles, I seafoamed it about 5,000 miles ago and I changed the fuel filter about 1,000 miles ago. My highway mileage is just fine, about 25 mpg. City is pretty bad though. I am untuned with lt's, ory, catback, lid, p&p tb, but I dont think it has suffered that much from when it is stock.

Forgot to add that i too have LT's, ORY, and catback untuned...so i still do well, but i think that could still cause you an issue.

I drive 1.5 miles each way to work and have as many as 15 traffic signals. I get about 11 mpg doing this and about 25 on the highway. I just found my DFCO was not enabled so I hope to gain some milage there.

Yeah right Terrell, the only reason u get 13 mpg in the city is b/c your in Knoxville with the hotties and your trying to impress the ladies. Dont tell me i'm wrong cause then you would be lying.

98 Formula, A4, 2.73 gears, lid and muffler only. 20-22 mixed driving and 27-28 highway and I'm not trying for good mileage. It's too much fun to get on it!!!

Current mods on sig...I get about 14-16 city (18 when i drive like granny and use the skip shift and shift @ 1500 rpms after 4th gear) and about 23-26 hwy.. i usually end up about 240 on a full tank. My car needs a couple of quick fixes right now. But lately its been around 270 and thats with running rich. 325 at my best when i didn't have my SES light on. If i wasn't going 80-90 the whole trip, i probably would have cleared 350-360 on a full tank. I imagine that it will be tons better once i get a lid and headers for better flow..
i was under the impression that when car manufacturers test engines for mpg, its not bolted on the car.. so when they give numbers, the car weight and exhaust piping and whatnot isn't considered.
