Thanks! I had the second O2 sensor replaced, and had my summer tires mounted on the steel rims (so I could continue using the smooth wheel covers), and the temperature dropped again, so I have had to try hard to get the average up to 43mpg (at a half tank).

I'm wondering if the Yokohama tires are higher rolling resistance than the Michelin snows -- my seat o' the pants meter says they are a bit worse. I'll pump them up a bit more, I think...

Congratulations on your 505 mile tank!

I will send you some of my extra vortex generators if you would like.

They didnt cost me anything and i would like them to go to a good cause

Hello,

Yes, For five tankfuls, I have averaged 45.5 -- it is nice to get results!

My wife just got an xD (heavier with larger engine and slightly worse Cd -- and her first tankful was almost 42mpg -- instantly, it is 44.8% above EPA...

I see you busted the 45mpg ceiling nice! I hope I get my turn soon.
