I wouldn't be comfortable with 225F.
The engine still needs some cooling when the weather is getting hotter.

After a while, if you want MPG increases i believe that you have to start splitting a few hairs. So That is what I'm doing.

Yeah, you get a bit here and a bit there, but it all adds up.

I was thinking of removing the hubcaps cause the steel rim is smoother and more aerodynamic. and i would also shed a few pounds with the hubcaps off. Maybe 3 -5 lbs.

If the hubcaps are not as smooth as the steelies, that's say 4lbs of rotating and unsprung mass removed, which is a good thing.
