Your engine is similar to all of those engines. I would treat it the same as all of those engines. Some members feel strongly that synthetic oil and a certain octane is better than other options for whatever reasons, and they may be right.
My 4-Stroke gets low-grade pump gas, and 1oz per Gallon of Sea Foam.
Seafoam is the reasion, i have seen 87 enthoanal at small engine repair sitting in a ice cream bucket for a couple of hours after purches,that had water in the bottom. Seafoam breaks it down and passes it through.
I mow quite often at the lake 5 hours each time and have tried both and after. have a lot of truble with 87,i will run nothing but 92 now,much better now.
