Another question that I have, is there an issue with oil contamination with the E85 like with alcohol? Would your gas ring gap still be "ideal" for the E85?
I see just a LITTLE oil contamination but if you get it good and warm it pretty much dry's it out. I changed the oil one time during the summer months with about 40 passes on it, just to check. I did the same as your thinking, I have my spare gas dom sitting in the trailer just in case
