I've used pump E85 for over 5 ears now in my S/P car with a AJ modified and prepped carb., the first batch was winter mixed and tested to be E75 which required jetting down 3 let sizes to get the most power and torque on a DTS engine dyno wrench
All the other pump E85 I have bought since then has tested to be E85 out of the pump up
I use plastic 5.5 gallon fuel jugs and when they sit in the winter full to half full the fuel in the trailer they will test in the spring to be E87 to E89 work I bought around 16 gallons three weeks ago for $3.10 a gallon boogie
I was told that the gasoline evaporates out of those jugs making the alcohol content denser work confused
As far as consistency run to run from early morning to late afternoon at the track I love it boogie up
