I get between 300-350 miles per tank, and thats half city half hgw. (2007 R/T stock 5.7 HEMI.)[sm=confused06.gif]

 

I am getting just about 20 mpg that is all around good combination highway and city. I am a little.......ok alot heavy in the pedal though. A better question is how long do these stock tires last? For some reason the back is wearing quickly.

 

What kind of tires do you have? If you have the Contis, they won't last long. I put new Goodyears on mine before my Contis were worn, but that's because I just didn't like the Contis. Poor traction, noisy, rough riding - but that's just my opinion.

Coming home from work yestereday @ 75-80, I resetMPG and I was getting 27-28.

My RT came with Goodyear Assurance tires. They are OK but I am going for wider lower profiles when these are gone. At the rate I am going I expect 25K to 30K and they will be done. For me that is the end of this summer I have 7K on them now.

Just put K&N cold airkit on, gas mileage seems higher but I will keep track. Car sounds better when you get on it!

 

Our is getting worse now,since header install .

 

its funny how headers have a tendancy to make your foot heavier.
