so I got e85 before I saw your email I put 4.5 gallons of E85 in with a full tank of 93. I also changed out my spark plugs with a fresh set of the Bosh plugs u sent me the link for a while back. the car feels a lot better. and I am game to put more e 85 in if you think that will help even more and get me closer to my goal. I appreciate your patience so far the experience working with u has been phenomenal and I will be recommending u to everyone.
