Agree, use commercially available fuel ----- I do however dissagree with the statement that you shouldn't leave fuel in the engine after running.
As I said -- lots of opinions. I should have been more specific -- I was alluding to not leaving high-nitro content fuel (25% for example) in the crankcase. I use 10% - 15% & I leave the fuel in there during the flying saeson, but I use after-run oil during long periods of non-use.
