What if I told you that the octane needs change by Altitude?

Someone mentioned weather, but we get 91 as highest in West Texas because we are approx 3000 ft above sea level.

Other higher areas might have 90 as premium and 85 or 86 for REG UNLEAD.

So, 93 for sea level, 92 for 1000 or 2000 ft, 91 for 3k ft, and 90 for 4k ft up.

The review is good for the altitude of test, weather that day, and yes, turbo cars could keep need for 93 at altitudes not selling it.
