Older car hoses can degrade faster from it. You also get less power per liter with the blend but overall no.

It also doesn’t “keep” as well (which is why you should burn non-oxy premium in small engines if you can’t get normal non oxy; or fully drain/run dry your lawn mower at the end of the season).

Learned this the hard way with my zeroturn mower this spring. Left a bit in the tank. Gummed everything up. Had to take an air compressor to all fuel lines and clean the carburator.

Reasonably priced well built electric tractors and zero turns can't come soon enough.
