I've read other threads about mpg but my most recent trip is still making me wonder. I filled up my tank @ Hess in Camden, New Jersey and reset the trip odometer. I went up to White Plains, NY for the weekend and went to fill up my tank again at lunch today. The trip said 302 miles and I only had to put in 9.1 gallons. That calculates to 33.1 miles per gallon.

No engine mods, approx 84k miles, and overdue for an oil change. I usually get 23 mpg. It was all highway miles, but that's still unusually high. Just thought I'd comment

 

33 holy great gas mileage batman.

The best I ever got was 32 but the car was only 6 months old....ah the good old days

 

Did your gas gauge go all the way up to the "F"?? It's possible that the pump shut off a little early...

also how fast were u going? i think speed plays a role. I bet u were going like 45-55 the whole trip...burns less gas i believe when u stay at lower rpm's and that's probably what u were doing...

 

I normally get just over 20 MPG in "spirited" commuter traffic in DC. I was excited because on the way home from the WVU game (Morgantown, WV to Herndon, VA) this weekend I got 29. NIIIICE...

 

I was going an average of about 70-75 mph (I covered 130 miles in 2 hrs to get there). Not flooring the hell out of it, but modestly increasing the accelleration. Believe me, I was certainly suprised myself. All highway miles - NJ Turnpike and Garden State Parkway.

I know I filled the tank up to full, because I went to fill up my tank today and it shut down at 9.1 gallons. I tried to top it off to the nearest dollar to get exact change on my cc, but the pump kept stopping any additional gas to go in.

 

Good tailwind?

 

I got 27mpg one weekend from Santa Barbara CA to Davis CA and that was with the A/C on the entire time with my speed around 80-90 (with a high of 115)....never had it that good since, just happened to be the first weekend I had the car (bought with 76k miles)
