The difference; I use ONLY 5% nitro and 20% oil (including 8-11% Castor) in my fuel; both for all my MVVS, high compression engines and for my past OS engines.
I would recommend this formulation to anyone running a two-stroke glow engine.
Dave,
I use 20% total oil, out of which about half is degummed Castor oil, for all ball-bearing. ringed and ABC/ABN engines. I have not had, or run, a lapped, meehanite piston, steel sleeve engine in a long time, but for them and for bushing bearing engines, I would use the same formulation, with the oil increased to 22%.
I break-in all engines on 22% oil. I think the richer mixture used for break-in of lapped engines does not require the percentage of oil to be further increased, but for lapped piston engines I would increase the Castor oil's part.
MVVS, by the way, prescribes 25% oil for their Diesels, but this is for another forum.
