Not really a tenth gen problem since the compression and cams are not radical enuff to get benefit of 110.

But you'd probably be better off with e85 no matter what.

I just learned that I have 100 octane relatively close to me, much closer than the nearest e85 pump.
I mean, I guess I can google it, but what station did you find in vegas has 100 octane? Been thinking about mixing 100 and 91 to get some 93-ish equivalent for my phearable tune

theres also a rebel on Tropicana a couple blocks east of the strip that has e85

100OCT is $8/gal near me and the arco with E85 half a miles away is $2.16/gal. I’ve never pumped either but might try the gallon of e85 +91 at the a chevron a couple miles away since I don’t really trust arco here yet. Regardless I’m stock so I doubt I’ll get any benefit

93 is recommended for my tune, 91 minimum. Only have 91, e85, and 100 octane out here unfortunately. The car loves a splash of e85 and it’s a noticeable difference in consistent performance so I may try the 100 octane mix since it’s closer to me.
I did the same thing for a while. I put mostly 91 and a couple of gallons of 100 octane to achieve a 93 blend when I was on TSP Stage 1. I forget how many gallons of each, it was a while back. And I realized for 10$ a gallon, it makes much more sense to just use e85. Even if you have to go fill up a few containers or something. But if you don't mind spending the extra money then I don't see an issue with it.

If you’re going to store E85 just be mindful if it sits for too long it will collect the moisture in the air and the fuel will begin to separate. Put that in your car and DEATH. Make sure to mix it around every now and then or don’t store so much. Those ethanol stabilizers don’t work either so don’t waste your money!

I put a couple of gallons in earlier as my monthly treat to my car. 101, right around the corner
