Probably not the best place for this but I just bought a Honda EU2000i generator for my trailer that i tow (there content fits right>).

manual says like 86 or higher for octane for the fuel.
I carry 93 in the trailer for the race car and am wondering if I can use that regularly if it might do harm other than to my wallet.

Rather not carry another jug for fuel, already carry three, two for the race car and one backup for the truck.

Plan to buy a companion for it in the summer to run A/C

I think you will be ok probably just will not be as fuel efficent as with regular

We always used 91 in all of our small engines when I worked at a concrete company. All honda engines. Only gonna hurt your wallet lol. Not bad with a gen that small though

Same here. All of the lawn equipment and toys get premium. Small price to pay for peace of mind that you won't have problems from detonation or preignition.

Won't hurt one bit but using high octane fuel on engines that don't require it isn't going to provide any benefit either.

I used to get a laugh out of all of the riceboy cars at the 94/97 octane pumps filling up their Chevy Cavaliers with high octane, convinced it was going to give them an extra 50HP.

It'll run cleaner!

It'll run cleaner!

That's a myth, actually.

To the contrary, some of the chemicals they use to increase the octane levels are actually rather toxic, and if you equate "clean" to "I'd rather breathe the exhaust from this versus that" then lower octane gas is actually far superior, especially on something like a generator that doesn't have a catalyst system.

Was talking to someone at the track about about and he told me I should look into a product VP racing fuels makes called SEF94. Said it was made for Small Engines (Small Engine Fuels SEF).

they have it on their site but does not look easy to buy and not really what I was thinking (wanting not to carry the extra fuel jug).

That's a 94 octane fuel again designed for small engines that need it - high performance go-carts or whatever. Using it engines that don't need anything more than 87 is a waste of money, really.

Been running 91 in mine for about 1500 hours and it keeps on purrrring

Won't hurt it, won't help it, but it will get marginally lower hours out of it per fill. Especially if where you get the 93 is ethanol enhanced to get the extra octane rating. In some *particularily* western states, 93 octane is 20% ethanol, where ethanol gets about 60% of the fuel mileage of an equivalent volume of gasoline.
