So, i found my problem, about two weeks ago i installed a CAI, and after that is when my MPG went to hell. I went to take the cold air out and put my stock back in. Well, i pulled the intake out, and my air filter was just sitting in the fenderwell, i guess i didnt tighten the clamp enough, but everything is good now. Cleaned my MAF, oiled my filter. Put everything back together. Happy driving every one.

 

howwww dooo you guys get so much out of your tank?? im lucky if i can get my tank to last me 240 and i try to drive decent, i only punch it like once or twice. and i just cleaned my fuel injectors and no difference :/

 

Do you have any mods, or aftermarket wheels? Seems like just about anything you do will make mileage worse, or in a lot of cases, make the driver more likely to punch it a lot more

 

i have a cai, and cobra r's with 265/45/18 and a short shifter. nothing else, but when i got it , all it had was the wheels and it lasted around the same. i wanna check my spark plugs and wires and see maybe if i change em, it will help a bit

 

This spring I replaced plugs/wires, did a fresh oil change, replaced the fuel filter and air filter. I've been running on wide 17's all summer long but I do drive quite a bit on the highway. Worst mpg she ever got was 25 and best was 33, when I drove from Madison to the Chicagoland Speedway.

Like I said, I've been running Cobra 17's with 245/45 in the front and 275/40 in the rear with a 100% stock V6 (well, not anymore ), and getting better gas mileage than my 2011 I4 Camry SE. Maybe I just got lucky with this one

 

Have a true dual exhaust, stock intake, gt rims/tires. i have the tires set 35/35 psi

had about a little over half a tank(bout 7 gallons).. from Los Angeles to San Diego(130+ mi trip) then back to Orange County(another +50-60 miles)....With all calculations to begin with I hit about 26-28 highway mpg.

not bad I guess since there was a bit of traffic in between and my average speed was about 70 mph.

 

my 98 gets at least 280 miles per a tank no matter how much I beat on it. On my last road trip with it I got a best of 27.9mpg out of it driving through TX cruising at 65 mph mostly...
