- Block off the radiator to the point that water temps run around 195 degrees. This needs to be adjusted periodically.

I have an 2010 a/t (wifes) that I drove my normal route (325mi) for almost a year. I had it up from 34mpg to 49mpg for that trip.
I can confirm:
- higher psi (45psi is better)
- Lower grill block
- keep engine at/under 2000rpm (52mph in this car, ever 2mph over = 1 mpg lower).
- Wai doesn't work if you have a mass air. My mpg went down slightly and the car was gutless. It also kicked down more (prob why it lost mpg).
Additionally, ethanol free gas gave me 3 mpg alone.
