RE: After Run Oil And Omega Fuel ( Morgan )
Oiling a motor CAN be detrimental if enough moisture is present when the oil is added. Oil floats on top of water. Mineral oil will not mix with water and the water is traped between the oil and the metal parts. If you store nose down the water will flow toward the bearings. If you add oil right after flying there will be some moisture in the engine. Best to run the engine dry and add castor or even synthetic oil as an afterrun oil. Or at least let it sit with the pistion at BDC for a while before adding the afterrun oil.
