No, not bad info. My manual says the same thing, so the fuel lines are designed to use ethanol fuel. These generators don't use a lot of fuel, so there is a good chance that without an additive you can have the separation--or use 100% gas. Cars go thru a tank in a week, that fuel may be in a generator for months. The only benefit for using a higher octane fuel than an engine is designed for is you're donating extra profit to the refiner/distributor/dealer. Every manual for every motor has the designated fuel octane requirements listed and there is absolutely nothing to be gained from exceeding that.
