Hello,

Another type of oil you can try is the Hobbico After Run Oil. I haven't used any of the other oils mentioned, but I really like the idea of using preformulated commercially available oil that is also relatively inexpensive and lasts a LOOOOONG while. As for application of After Run Oil in the engine you simply open the carb and if you prefer take the glow plug out, and then just put 3-4 drops into the carb and the glow plug hole. Then slowly flip the engine over(doesn't matter if you reinstalled the plug or not). I have found that if the engine sits around for a month or more(rarely ) the oil "disappears", that is the film of oil is no longer noticable on the piston. If that happens, I preffer to oil the engine again before I take it out to the field.

Search the RCU boards for after run oil threads and something should come up.

Happy flying!
