Nothing magical really. but, here is what I do: change the oil every 25-35 hours using whatever autozone has on sale; change the oil filter at 200 hours; keep the fins clean, get any oil leaks fixed asap, change air filter as needed.
The engine has had lots of oil leaks: breather gaskets, sump gaskets, governor seal, etc. Lots of coils, carb rebuilt twice. Never had the heads off. Uses about 8-10 oz. oil in 25-30 hours. Engine does not smoke. Runs pretty well but does not have the same power as new.
