Hey guys, I want to run premix. i just want to see the effects for myself. So im going to run premix in one full gas tank. Can I still run premix with my OMP attached? I know what kind of oil to use but just wanted to know if its safe to use premix with my OMP still on. Oh yea I remember reading lower octane on NA is better, is this true? I have a rebuilt ported engine with 7 k miles. Only real mods is a straight pipe. So my fell rx7 enthusiast, running premix and lower octane best for my car? Thanks!

Premix with OMP is no prob, 400:1 ratio is common in this application...

NA's run fine on low octane...

thanks wayne, but do they run better? or really no diff.

Hmm, never actually ran anything "over" 87 in mine, not gonna spend the extra money just to perform a trial, either. It's not like it provides "more bang for the buck, contrary to popular wisdom... NA's just don't need a higher octane, due to the relatively "mild" compression pressures, compared to the boosted/ high compression cars...

oh i see. ill try running 87 in mine and see what it does. Also the 400:1 ratio. is that ounce per gallon?

128:1 is an ounce per gal, so you're looking at something between a 1/4 oz and 1/3 oz per...
