my idea for after run oil is marvel mystery oil, wall mart has 16 and 32 oz. its hard to find the one gal sizes. some auto parts houses has one gal. allso its good for your gasoline street truck, in the gasoline, but i wouldnt put it in the street truck crankcase. mmo doesn't have a pressureized can any more, i found a wd-40 hand spray bottle to put the mmo in, when you are are done bashing take the air filter off and squart two pumps in the intake, and spin the nitro engine over for a few seconds, dont put more in it will be hard to start. when you take the nitro engine apart use permatex ultra slick engine assembly lube item # 81950 to lube the inside parts, when you start it, it will smoke for a while so dont worry. any good auto pars house should be able to get it for you. #81950 is good for ball bearings also.
