Aviation Oils / Aviation Oil

For the majority of aircraft piston engines the selection of the right grade is important to maximize engine performance and engine life. The AeroShell Oil and AeroShell W Oils come in four grades: 65 and W65; 80 and W80 and W80 Plus; 100 and W100 and W100 Plus; 120 and W120. The grades differ only by viscosity and thus cover the needs of all reciprocating engines now in airline and general aviation operation.

AeroShellDirect.com offers Aeroshell Turbine Oils too. AeroShell 500, 555, 560 and 750 is available. AeroShell Turbine Oil 500 is a 5 centistoke synthetic hindered ester oil incorporating a carefully selected and balanced combination of additives to improve thermal and oxidation stability and metal passivation. AeroShell 555 is advanced 5 centistoke synthetic hindered ester oil incorporating a finely balanced blend of additives to improve thermal and oxidation stability and to increase the load carrying ability of the base oil. AeroShell Turbine Oil 560 is a third generation, high performance, low coking 5 centistoke synthetic hindered ester oil incorporating a carefully selected and finely balanced combination of additives to improve thermal and oxidation stability.

AeroShellDirect.com stocks all four grades of AeroShell Oils. AeroShell straight mineral oils are blended from selected high viscosity index base stocks. These oils do not contain additives except for a small quantity of pourpoint depressant (which is added when improved fluidity at very low temperature is required) and an anti-oxidant.

AeroShell W Oils 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.

AeroShell 15W50 is a unique blend of high quality mineral oil and over 50% synthetic hydrocarbon base stocks, plus the AeroShell Oil W ashless dispersant additive system. This semi-synthetic blend offers high performance in a wide variety of applications and conditions. AeroShell 15W50 provides outstanding wear protection for critical camshafts, lifters and other high wear components.
