Final Octane when mixing

Agreed. In fact there are a couple of posts around here somewhere where all of that is explained. Mixing E-85 with race fuel is a no go as well. Any of the pretoleum based octane boosters ( including lead ) will not effect E-85. In fact when E-85 is mixed with these fuels it dilutes the mixture and can actually lower the octane rating of your race fuels. E-85 has great knock supression qualities itself. If your going to really run high boost, get some bigger injectors, run 100% E-85 and be done with it. I actually have 2 chips so I can switch if I want from 93 back to E-85 and so forth.
Remember E-85 or mixes thereof cannot be rated by the RON or MON methods.

Duly noted.
I remember reading that thread.
This WHOLE thing started out like this;
I told my buddy: "Go add 3 gallons of E85 to your tank and lets see if your KR is octane related". (It was)
So I told him: "Keep the % of the mix about the same (25%) for this weekend driver, or we will need to re-tune".
Well, he is 73 yrs old and was asking me: "How many gallons of each (93 and E85) do I add when I get to the pump"?
So I did the spreadsheet thing, to print out the "breakdown", which now tells him "How much of each fuel" to add "each time at the pump" to keep the mix close on his safe tune.
I added the octane as this applies to other "Race gas mixes", since E-85 is technically a "flex fuel", not a "race gas"

What do you think about this? Is it tacky, I kind of like it.

why do you even have to deal with the cashier at all? Can't you just pay at the pump with a credit card or something and not even have to deal with anybody?

Yea....sure you are. I, for one, certainly do remember those E85 cars that Buick built in the 80's. It's a good thing you bought that replacement emblem and brought it back to it's original showroom condition. :biggrin:
