Ive read someone say that when you switch a dune buggy engine over to E85 it will burn 20% more gas. Its part of how they change the tuning. So i guess for a generator it would need larger jetting. Just a rough guess and fun to think about. Or if you camp at 4000' maybe turn the alt screw as low as it goes.

This is news to me. I have never heard of a gen running so poorly on 87 that you had to run 91 or it dies. All the small engines I have ever had, generator, lawn mowers, motorcycles, tillers etc, have always run on any old gas I had around and have never shown preference for any octane (though the Moto cross motorcycle does have more power in high octane)..
I would look elsewhere for over-heating problems before looking at gas.
What gen do you have?
Did u check for a mouse nest or other debris on the cooling fins? The Onans are enclosed so mice or rodents can build nest in there and cause a hot run.
Oil at the right level?
Correct oil, usually SAE 30?
So, Im curious... someone mentioned it so, what happens when a gen runs on that E85 gas? I would never even consider it, but if I had no choice this is an option?
I only ever use 100% gas. Solar is king for me unless I am running AC.

This is the best choice, if available!
Adding ethanol, will cause a more lean condition, and can cause more heat, under load. The OP may have used a higher octane 89 fuel, that contained more ethanol, and caused over heating, of his small gen engine, while under max load?

Anyone have experienced issues running a different grade?

For the amount I use my generators anymore, the cost of premium is insignificant. I never drain the carb, but I do run them monthly. I also have an issue with running them dry versus draining the carb. If you add a shutoff there is still gas in the carb that can and will varnish over time, it just isn't enough gas to run the engine anymore.MFL wrote:

Any decent quality brand generator has bee tested on E10.
Don;t store any generator with ANY FUEL IN THE CARBURETOR for more than about a week ! If your generator does NOT have a fuel shutoff valve, you can add one for $10-$15.
