RE: ansoil mix for DA 100
I'll have to agree with RCPilet. With any kind of decent care these engines should run for years. I bought an old plane with a G62 and I don't know how many flights it has on it but it has been run for several years and I have been flying it for 2 more years and it still runs strong with no signs of giving up. I know I have never run Amzoil through it. I am seriously considering getting my lubrication from the hamburger stand down the street. I know the way that the grease coats my stomach that it just has to protect an engine from wear. The parts couldn't possibly touch one another or rust.
Seriously though good ventilation is just as good as good lubrication. I would rather be in error on the rich side rather than the lean side of both. Just my 2 cents worth. Bill
