Because the lower octane stuff has ethanol in it and people say that is bad for our engines.
Damned if you do, or don't.
Toadmund, I'm blessed in that I can buy 100% gas here in my home town. When I use 100% my engine sounds like this errrrrrrrrr... When I use gas with ethanol it sounds like this erred_____erred______erred... I've got an older B&S lawn mower and the same thing happens to it as well.
I do know the ethanol amount does vary from company to company. I'm not sure about octane grade however.
