Probably not, most regular gas is 87 octane, mid grade 88-90 and premium 91-94. I have the earlier EU2000 generators, wish I had known about the EU2200 coming out and waited a few months and gotten it. I use alcohol free gas in mine which is 89 octane and no problems. I use that gas in all my small equipment, including the big lawn mower and generator which each has a 25 hp engine. I am running mid range in everything with no long term problems, my chain saw is pushing 30 years old and still going strong.
