RE: Saito .72 4-Stroke - Caster oil
Masonman, I think we may have discussed something similar before and no doubt you will get a flurry of different opinions so here goes mine. Omega has gummed up several Saitos for me and I have seen several others just this past summer that were gummed with Omega. These engines have many gallons of fuel thru them. No big deal to clean them and if you think you need the added protection. I have others that I've run for years on Cool Power with two ounces of castor added to a gallon. On ocassion when I've removed them from the plane I take a look inside and to date they have all been shiney clean. If I were you I would stick with the Cool Power but it would take the Omega several gallons to gum it up. My own experience with cool power is that it gives me several more rpm than omega all other things being equal.
