Thanks for responding Larry a friend of mine uses Tru Fuel, 92 octane, non ethanol premix 40:1. He swears by it. He uses it in chainsaws, trimmers. It also uses a full synthetic oil in its formulation. I'd like to use Ethanol free fuel but can't seem to find any gas stations around the Philadelphia area I live in.
I avoid it at all costs. I prefer to customize my ratios of oil to gas. Different engines require different ratios. I'm pretty sure some also contain other additives. I'd only use it if I checked the msds first and it also happened to be the exact ratio I needed
