Model Forum / Radio Controlled / Land Models / May 2006After-run oil?
I heard Doc say that it's important to use an after-run oil in the Savage, and he uses Marvel Mystery Oil. The question is, how exactly do you use the oil?

After motor quits from running out of fuel, continue to try and start the engine until it no longer pops. This will ensure that all the fuel is out of the crankcase. Alcohol is hydroscopic and absorbs moisture, hence any leftover fuel will attract water and increase the potential for rust. 2. Remove airfilter and open carb all the way. 3. Squirt some MMO down the carb. 10-15 drops of MMO is sufficient. 4. Using pullstart or rotostart, turn engine a few times to distribute the oil thru the engine. 5. Close carb. 6. Reattach air filter. This protects the internals from rust and also provides startup lubrication for the next time you'll run it. MMO has a nice solvent package in it as well and it will actually clean your motor internals as it sits and burns off.

The S-25 now has 10+ gallons on it and still has full power and great pinch. The Sportwerks .26's have around 4 gallons (truggy) and maybe a gallon (buggy) and both still run like new. The only thing to watch on the Savages when using after run is the one-way bearing, which is inherently weak. If she floods on startup d/t the oil + fuel in the crankcase the one way will crap out. On my Savage, I pop the glow plug out, flip er' upside down and run the roto for a few seconds to blow the oil out of the crankcase before I try to start it. The .26's in my other vehix don't have this problem as the Sportwerks .26 one-way is indestructible. Doc The bearing on the t-maxx has same prob GERRY >>> After-run oil is important in ANY nitro engine.

Interesting! Doc When we first got our T-Maxx, I flooded the motor while trying to start it, and destroyed the bearing. I learned quickly to pull the plug and run the oil and fuel out before trying to start it. GERRY >> Yes sir > > I have heard that from some people, and others state that it's > indestructible.
