Doing my first e30 tune and was wondering if I can just run the car to about half a tank add 3.3 gallons of e85 and top off with 91? I see on stratified's site that you have to run the car near empty then do the mixture. Also, do you need to wait to let the 2 fuels blend? I plan on premixing my e30 in a gas container for future fill ups.
