Castrol Aviator AD grades are additized ashless dispersant piston engine oils that meet specification SAE J-1899 (formerly MIL-L-22851D). Castrol Aviator AD grades can be used to top off or replace any other ashless dispersant piston engine oil that meets these specifications. In addition, Castrol Aviator AD contains an additive package that meets the requirements for select Lycoming engines that require the anti-scuff/anti-wear additive package, LW-16702.
Application (Always refer to engine manufacturer's guidelines)
- 4-cycle reciprocating aviation engines (including turbo-charged and fuel-injected) where an approved SAE J-1899 or MIL-L-22851D oil is specified
- Aviation radial engines
- Engine break-in where straight grade oil is not specified by manufacturer
- Lycoming and Continental® horizontally opposed aircraft engines
Features and Benefits
- Superior rust and corrosion performance providing total engine protection
- Excellent anti-wear/anti-scuffing properties providing greater bearing protection (contains anti-wear additive required by some Lycoming engines)
- Low temperature fluidity and high temperature stability providing easier start-up and reduced engine deposits (better engine cleanliness)
- Fully compatible with other monograde and multigrade products approved under SAE J-1899 (MIL-L-22851D) and SAE J-1966 (MIL-L-6082E)
