I think those are some good tips that I can agree with. I still feel that staying in EV as much as you can will get you closer to a 40mpg tank than anything else. This winter and spring got me over that many times. The A/C is a must during summer here in SO. FLA. so I will test those tanks this winter. Now that the FEH is broke-in, I'm shooting for 43mpg when it cools off. Also may take the tire presure from 40-41psi to 42-43 and see what that does.
