What gasoline do you use? Anyone use e-15 to e-85?

Since ive got a 38 gallon tank in my tundra I figured id get a tankfull of e-15 and see what type of milage i get. So far it's hard to tell a difference between the e-10 that most gas stations sell.

I use e10 in all my vehicles - even the motorcycle. I lost about 2 - 3 mpg compared to conventional gas. Very few places even sell the higher e15+ in my area.

I got 16.9 mpg with e15 at highway speed 60ish over about 50 miles. That's acceptable.

i'm not sure but major metro areas are all attainment vs. non-attainment areas for ethonol. Most of the us is e10 isn't it?
