I am getting very good gas mileage on my 2004 Crossfire. I have averaged over 30 mpg on a tank. I almost aways average 29 or better for 85% freeway and 15% city, I get stuck in traffic 3 times a week. Averaged 29.92 on my last tank. I have made some very simple changes that have given me great gas mileage. The first was I pulled the fuse on the spoiler. I found the automatic deployment irratating and obstructive for freeway driving. The second was using the crusie control which I set at 67-68 mph. This eliminates that urge to go 110 when some A-hole irratates you. Finally I turn the engine off at an extremely long traffic signa (3 1/2 minutes)l near my home.

I was wondering if anyone have some suggestions?

a lighter wheel/tire combo

 

check your mileage at different speeds,, my son has a new Outlook and we checked his mileage at 60 =29mpg at 70 =27mpg at 75=27mpg at 80 =23 mpg so so at 60 or 75 is his running speed for highway mileage. jim

 

sometimes a new intake or exhaust can give possitive effects on mpg..

 

take anything you dont absolutely need out of the car to save weight

 

Good tires and a perfect alignment made a huge difference in my mpg.

 

I found that keeping the car under 70 mph is key..sometimes it's hard to do on the interstate...but got over 32 mpg on my last short trip. Using the cruise helped a lot..
