Using premium is a good point because you can afford to lose more octane points for regular-requiring engines. P.S. Thanks for the link the other day on the home generator setup. I still have my disposable consumer-grade 3600 rpm generators. They only have to last through the amount of fuel I have stored.
You are very welcome. I’m pleased you found the information useful.

In a portable, gasoline fueled generator, should the tank be empty or full for long term storage?
