I have a hard time believing that open windows would make your mileage go from 40 mpg to 32 mpg on the freeway at 75 mph. Maybe its true? Replies to this message: dake (Oct 03, 2009 1:43 pm) thegreyone (Oct 04, 2009 12:05 pm)

Replying to: nippononly (Oct 01, 2009 5:17 pm) I once read somewhere that when tires are brand-new, they will get less mpg because of the mold release stuff still on them. I don't know if it's true or not. Replies to this message: nippononly (Oct 04, 2009 10:34 pm)

Replying to: mcdawgg (Oct 04, 2009 5:23 am) Well, I hope so, because I want my 42 mpg average back! :-\| Certainly as tires age, the rubber hardens even if they still have a lot of tread, and that hardening decreases traction but increases fuel economy.
