Okay, checked the onboard computer on my 2006 Charger RT. It says my average mpg since purchase, yes I never use it and dont reset it, is 15.7 mpg. I check my mileage every fill up and my lowest ever was 17.94 mpg, highest evr was around 23.5 mpg, and I would say my average is around 19 mpg. Therefore, we can see the computer is over 3 mpg off. Lets wait and see what the actual figures are. I am very capable of paying for gas, but this is something I look at all the time. So again, if you have actual miles per tank or something please let us know.

Thanx,
