Im going to trade in my 03 sebring because well, I just dont like it anymore and I would like another M6 LS1.


My bolton car wasnt bad on gas, it was better than this sebring!



But that was with 4.10 gears, im thinking about going with 3.73s for this one since its going to be a Daily Driver.

I would love to throw in a set of 4.56s but I do alot of city driving and highway.


So my feature mod list for good mpg is

Ls6 intake(or a cheap fast used) throttle body, long tubes, true dauls dumped,pulleys,lid with free mod ramair, nice tune,3.73s, LS7 clutch

Forged 348. TRex, heads, fast 90/90, pacesetters, o/r y, magnaflow catback. Its a six speed, with a 9" and 4:10's.

I get around 20-22 mixed driving being easy on it, but it can go way downhill from there lol.

Heads/cam with 4.10s. I got 24.86 on a trip this spring with a passenger, luggage, and a/c on running 75-80 in the hills of Tennessee. It has only gotten under 20 mpg ONCE, and that was in the upper 19 range. I usually get 22ish driving it however I want, some beating, some normal driving, with town and rural driving combined.

hmmm most of these cars are M6's what a surprise they still get good gas mileage! in my A4 with my mods at 70-75 i get 24-26mpg but i only drive highway so i get about 400 miles to tank everyweek

Mods in sig and I pull anywhere from 17-21. I just got the 9" in with the new gears so it may go down a little more...

kevin's_00ss

dang i do alot of mixed driving and only get 170-180 miles on a tank. about 10-12 mpg i guess.

the best i ever got was 18mpg just on one tank strait highway in one day.

when i used to just drive city driving i got 7-10 mpg about 110-120 miles a tank

thats with stall and 3.73's

Mix city and highway driving, I get about around 190 to 230 miles per tank. On straight highway driving, IIRC I get 350-380 miles per tank.

CheaTR cam, full intake, pully, cat-back, 3.73's in an M6. I average 19-22 in my usual 50/50 street/hwy driving. 19 if I feel like driving a little hard. 22 if I hit the cruise control. On road-trips i'll get 26mpg. Back when I had stock gear ratio and my LS1 intake, I got 30mpg on a road trip in the middle of July from SF to Phoenix at 80mph, a/c blasting.

110,000 miles on the clock and an M6 with most bolt-ons/cam/12 bolt with 3.73 gears and mixed I get 20-22 mpg on average, the 4.56's should kill that when I get them though

Everytime this question is brought up, why do people like to give the gas mileage they got on a crosscountry trip with few stops and good conditions? I never understood it. That isnt they way that you drive the car most of the time. Not that I care, and not that this thread is as bad as most, but I was just wondering??? When people ask what is your MPG, the typical response is, "I got 32 MPG on a trip from Wyoming to Kansas........."
