Using partial fill of e85 in cl600 biturbo ?
Hey guys
without guessing , has anyone run full tank or partial tank of e85 in their biturbo m275 v12? Any issues or improvements to a stock car ?
Here in CA, e85 is a dollar cheaper per gallon and octane is. Much higher (110+) than the 91 unleaded supreme we can get here which is the highest octane we can get .
im thinking of running maybe a third tank of e85 plus 2/3 tank of regular 87 octane unleaded . Seems that would result in about 95 octane fuel at far less cost than even regular unleaded gas .
Looking for people who have actually used e85, and any problems or parts Needed to prep the car to use it - not just opinions on what you think of it .

I do, since a while, random
33% is perfect, 45% fine
you have to go in Xentry - ME-SFI 2.7.1 - correction programming - Enrich
the other way is to get your injectors enlarged 33% by a specialist, then you can run 100% E85
both might get you still run a bit poor, but it is fine, just creates head in the cylinder when poor
even better, re-tune your ecu with the larger injectors
if you have i well tuned, you'll get your engine temp 15 C down with 100% E85
then you can tune your turbos up even more and get lots of more HP
