Thoughts on running the factory OMP with E85
 

I'm in the process of converting to e85/flex and going over the premix options. It looks like Redline premix is the best but Howards experiences are a little worrying so I think I'm going to runt he factory OMP as well. Since alcohol washes away regular oil, does that means crankcase oil is out, right? If so, that leaves the RA adapter. On their website, I just see the s5 electronic and Renesis adapters - I'm s4. Am I missing something?

S4 is a Mechanical OMP vs. the others being electrically controlled.

You can look at my build at how I'm doing S5 Turbo II Electrical OMP + e85.

I know - all I saw was about the electric ones.
I'll check out your build thread about your setup. Thanks!
