DUDE!....mate!..... fellow county men! You're going to have to start running this stuff, systematically and taking notes and reporting back to us. It'll be like a wine tasting or something where you tell us the vintage and how the IP responded, and if it was a robust full bodied fuel or more of a table oil. You can tell us if your exhaust was like a light chardonnay or maybe a darker merlot! When I was getting into this waste oil thing, I even saw where some guys run crude oil.Anyone have any experience with aviation oils, I have a never ending supply of aviation oils from a mate, apparently there pretty clean cause of the strict service intervals, are good too burn?
