Has anyone ever mixed the two together, small amount of E85 into mostly full tank of super?

We also have E15 here all over the place. It runs well with that. I get much better MPG than E85 and a bit more power than running straight 91 octane. The E15 shows 88 octane at the pump but it sure runs better than the 91.  It's only 10-15 cents higher than E85 so I am trying that this winter.

I would not go 100K miles with same plugs at all! These GDI engines EAT,FOUL and CRAP out so called 100K plugs in 60K. Do yourself a favor and @60K toss em! THEY DO NOT LAST 100K

It's called being proactive. I don't wait until my brakes are metal on metal before I replace.   While it might not add any performance, it wouldn't hurt to do.

I replace mine every 30-35k no matter what even if they look alright   Sent from my Z981 using Tapatalk
