Klotz Race Gas?

Just curious to see if anyone has had any experience running klotz 100 high octane race gas. They offer free shipping right now on orders over $150 (which would be orders of 2+ cans). Just seeing if this would be a good alternative to pump gas in a slightly modified 4 stroke and I’d probably run it in my 2 stroke as well as apposed to Sunoco 110.
