Well I have to say I am finally starting to get decent gas mileage.. My 2k2 now has 6500mi. I used to average between 19-21MPG, now I am averaging 23+. I have not changed anything about my driving habits. I have changed one thing though.. I used to run Sunoco Ultra 94, because it was the highest octane here in the northeast. Now I have started to run Mobil 93 octane and have noticed a slight jump in MPG.. Maybe it likes mobil better, or is the motor finally broken in completely ??? Its just weird how right when I switched to Mobil I have gotten better mileage, sorta like I just flicked a switch... Oh well. Just figured I would tell everyone to see if they have had similar results.... The motor does seem to run a tiny bit smoother...

Oh forgot one thing.. These mileages were calculated separately from the trip computer... Trip was reading 27 when I get 23, and 23 when I was getting 19ish...

 

I'm having a bit of a delima on gas mileage. I was getting 23 city and 26 hwy. I'm now getting 19.5 mixed with 65% being hwy. It all happened after hitting a speed hump going 30. I've checked the car and there's no visible problems.
