AII parts of the FS 400 are automaticIy lubricated by the oil content of the fuel mixture.
During the running of the engine, as well as while the engine is sitting properly mounted with the drain nipple pointed down, the excess oil will leave through the drain nipple. To protect your airplane, connect silicon tubing to the drain nipple and have it release the oil outside of your aircraft.
After you complete your day of flight, run engine dry (removing fuel line from tank) to remove all methanol from the engine. The remaining castor oil in the engine will protect the engine. Be sure to use after run oil, SEE NEXT STEP!
Make a habit of using after-run oil in your engine after each flying session. This will prevent rusting in the crankcase as well as preventing the excess castor oil from solidifying and locking the engine.
