Aeroshell W 100 Piston Engine Oil, Bottle of 900 mL

Aeroshell W Oils, Including Aeroshell Piston Engine Oil W100, Were The First Non-ash Dispersant Oils To Be Used In Aircraft Piston Engines. They Combine Non-metallic Additives With Selected High Viscosity Index Base Stocks To Give Exceptional Stability, Dispersancy And Anti-foaming Performance. These Additives Leave No Metallic Ash Residues That Can Lead To Deposit Formation In Combustion Chambers And On Spark Plugs, Which Can Cause Pre-ignition And Possible Engine Failure.
