97 2-stroke sportsman 400 fuel question

Hey all,

I was hoping to get some help from you experts regarding a fuel question.
Since this a is an older 2-stroke, I understand that ethanol is even worse for it than most other engines.

The only non ethanol fuel in the area is 100 octane low lead at the local airport. The dealer recommended I use this but I was wondering if you all had any thoughts. The only other options are not feasible as they are hours away.

Thanks for looking!
