I'm not much of a motorhead (yet) but my next door neighbor is.
He swears by Citgo gas as it doesn't contain 10% alcohol. He runs it in all his cars, his 2 Harley's and all his lawn care equipment.
He said he noticed quite a bit of difference in his 2 stroke mower and leaf blower- said that both engines run noticeably smoother.
Anyone have a similar experience?
