I live in western Colorado, elevation 4500 feet. I cannot find 93 octane here for my new ZL1 Camaro. Ideas appreciated.

You don't need that high of an octane at that high of an elevation

+1

Just use the highest octane available where you are. Can you get 91?

I noticed that some high altitude locations sell 85 as a base grade instead of 87.
I would also avoid using any aftermarket octane boosters without doing some research first, I did this once and was really unhappy when I looked up what was in the STP stuff I had bought. They also tend to do very little actual octane boosting...

93 isn't available in all sea-level states. 91 is fine.

On a normally aspirated engine? Absolutely....... But his Zl1 is supercharged. Under max boost he may want 93 octane. No big risk as knock sensing is very protective these days.

Use the 91 and accept a bit of power loss at WOT.

California only has 91 octane at every elevation, sea level even. Those guys run 91 in their supercharged GM V-8s, Your tune may not need 93 octane or benefit from it.

You can buy VP unleaded racing gasoline (it's expensive - like $6 - $8 a gallon) in 5 gallon cans, and add some to each tank once you arrive at your home.

Knock sensor will retard engine timing so no need to worry.

Just curious, but what do you think you're really accomplishing with that mixture? From doing the math, 1 qt of 98 octane plus 19 qts of 87 octane to create a 20 qt (5 gal) mixture gives a final octane rating of 87.55. Since you're not raising the octane much at all, what's the point?

Is the relationship between octane and chemical composition strictly linear?

I suspect it’s not...

91 will work, otherwise maybe look around for bulk purchases of octane boost?
