Another thought about FJ/Pilot... my gasser hates FJ/Pilot regular gas ! I can not only feel a power difference but have calculated a 0.3 to 0.5 mpg difference versus using Loves, or Texaco fuels. My 8.1 gets best mileage using Hess Brand regular gas !
Might not seem like much but when you consider the cost per mile of driving an RV and the wide choices we have in fuels why not use what feeds your beast the better performing fuels.
