91 or higher states the owners manual (but who reads that thing?)

I've only fed the Goat Sunoco 94. Then again it only has 2,200 miles on it.

The Tahoe drinks 89.

Having 16 cylinders isn't always the best idea, but it is the most fun.

..... don't know if I'd do that on a stock goat, but, as long as it's unleaded it should be relatively safe. BTW, get ready to replace the plugs.

Around here, the highest you can find is 91, unless you want 104 octane racing fuel for $5+ a gallon. Wish I could try 93 and see if it makes a difference.

based on scientific research, the gain from 91-93 or 93-94 is very marginal as opposed to the gain from 87-93 or 89-94.
