Aeroshell W100 SAE 50 Aircraft Oil - MIL-L-22851D

Let the SkyGeeks know if you have specific questions about AeroShell 100W oil or the other Aircraft Engine Oil we have for sale at SkyGeek.com.

Aeroshell Aircraft Oil by the jug, oil by the case, or oil by the drum, we’ve got it here at SkyGeek.com ! The AeroShell 100W Oil is made specifically for 4-Stroke cycle certificated aircraft piston engines.

AeroShell W Oils are intended for use in four-stroke cycle certified reciprocating piston engines, including fuel-injected and turbocharged engines. AeroShell W Oils are not recommended for use in automotive engines. For automotive engines converted for use in aircraft, the specific engine manufacturer or the conversion agency should be consulted for proper oil recommendation.

Most radial engine operators use AeroShell Oil W120 in warm weather operations with AeroShell Oil W100 or AeroShell Oil W 15W-50 being used in cooler ambient temperatures.

AeroShell Oil 100W or AeroShell Oil 15W-50 are the common choices for most operators of Lycoming and Continental flat engines but, during colder parts of the year, use of AeroShell Oil W80 in place of AeroShell W100 Oil would be an excellent choice.

Although some engine manufacturers and overhaulers suggest in their service bulletins the use of a straight mineral oil in new or recently overhauled engines for break-in, other rebuilders and manufacturers especially for engines such as the Lycoming O-320H recommend use of an AeroShell W Oil for break-in. Operators should therefore check with engine rebuilders or manufacturers for the correct recommendations for the specific engine.

Although it was planned to replace the British Specification DERD 2450 with a DEF STAN specification this has now been put into abeyance and instead the SAE specification has been adopted.
