Today United E85 costs the same as 91. E10 is actually cheaper, what is going on? I think now that they mix 98 to make it 107 octane they're charging more. I'll still use it though =)
I accidentally bought HPR5 when it was on special the other day, never thought to check its E85 suitability... It isn't listed in Penrite's explicit list of E85 oils...
Is this going to be a problem?
Wideband to narrowband scaling is included with the flex stuff.
