I search out ethanol free at any cost and grab 2 6gal jerry jugs to keep in the garage to fill the atv's.
Its crazy how much better and less issues you'll likely have when using it.
Needless to say i do add additional piece of mind, Lucas Marine oil Fuel Treatment, a little goes a long way and never had an issue.
If you cant get ethanol free, Highest grade "Tier-3 fuel" is the next best. Google tier-3 and find the place near you.
Good luck.
