Well it isnt just my engine that chugs gas,... I'm glad to see Hemieater. A 4 hour aggressive trip with My car club came into Carlilse custom show at 10.8 but a guiet ride home has it back to 14.2. It was car'* first highway trip and now has near 2600 miles.I havent seen a 15MPG since I bought it. The $3.32 per gal. has tempered my foot. Crusing with car and nitrous has gotten to be a costly habit

Hemieater...our GXP'*.....lol I think its the otherway around.

10,000 miles on mine and I'm getting 21 mpg. I don't drive particularly hard but I put my foot into it a couple times a day.
I was only getting around 17 in the winter, probably from longer warmups.

Well filled up Tuesday 5-16 (Prem for Reg Price $2.65 on super Tuesdays) and computer is now showing 14.8 AVG for 1/4 Tank. Wife tells me its my foot? Dealer tells me put some miles on it and stop washing it and just parking it in the garage.

After a weekend on the road, and no nitrous runs.....I am back to 13.8. Odometer now at 2800. Motor seems to be loosing up alot and tranny shifting as I want it using the gas pedal.

Everything on mine felt tight until 7500 miles or so. She pulled noticably stronger after that point too.
No 1000 mile break-ins with these cars.

13.8 your you drive a bit fast dont you...lol I think I am at 16.8 but I drive the car once a month these days...but when I do I drive pretty quickly.

That may seem low but the truth is almost all my miles are two lane country road and city miles. Car seldoms see'* the highway and I am a FIRM believer in not using 4'th gear in an automatic unless your on the highway. The constant shifting between 3 and 4 really what wears a tranny. My cabs lasted a lot longer once I started that practice. Went up to Ithaca today (highway) and she read 15.2 when I got home.... A new best for my car.

Yeah and out cars feel much faster in 3rd than in 4th

Plus they do at least 129 mph in third (at least mine does).
Who needs fourth?
