Re: E85: E70, E74, E80...changing pump mixture a problem for tuning?
Ya, and even if they change at a certain date, I usually don't see too many cars filling up at the station on E85. So even if they switch to 85% say, March 1st, They probably still have a tons of the 70% in the underground tanks. So 85% may not even be coming out of the tip of the gun until April for all we know.
But could you post up those dates?
