Oh 100% correct. The 10% ethanol actually hurting our mpg on our rigs. Our systems were designed for 100% gasoline. Granted the engineers at toyota stated that the older engines should run with up to 15% ethonal in the gas without damaging things that's a 5% more loss in mpg.
I honestly think this is the cause for the fuel system issues.. the ethonal is eating the deposits out and clogging the filters and injectors. As this makes the most since with the age of the rigs and why people are having to clean and replace the injectors.
