There both at the same gas station im sure the E85 is cheaper 100 oct is like 8 bucks a gallon. What do you think the mix should be if i got like a half tank of 91?

3gal to a tank is E30. You have a tune? 1.5gal if your at 1/2 a tank of fuel.

Personally my car loves E30-E50. Until today... It was not happy today at all.

This may help figure out also if you have a smart phone you can dbl chk at the pump to make sure you get the right or close to the right mix..
Razor is it better to error high on E85 or low staying closer to non ethanol gas? like mix and get a E36 or a E43 when shoot for a E40 mix ??

LOL "Mommmy"

Also this thread is starting to look like a BMW thread (E36, E46...)

 

[Sourskittle]

Lol. I was wondering if anyone would catch that. My daughter saw it and said, "why is it spelled like that?".

Better to error on the high side but honestly no good tuner should be tuning to the bleeding edge of Ethanol mixes to make a +/- 5% in Ethanol percentage change a big deal.
