My state is going to BTEE come January which, is the ethenol gas additive! we now have the BTE which they are doing away with due to lawsuits for ground water polution ! I guess it will eat anything rubber in time which is a concern for maybe engine damage in future. Hopefully people will lobby against these bozo's. I remember when they had the gasahol (corn) derivative that people raised hell about screwing up cats and valves ! I'm running turbo-blue (5gals) everyother tank hopefully it will keep fuel system clean ! Anyone know of other States useing this crap??
