Ashless Dispersant Monograde Aircraft Piston Engine Oils
AD 100/120

Description
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)

Approval Status

• SAE J-1899 (supersedes MIL-L-22851D)
• FAA Airworthiness Directive 80-04-03-R2
• Lycoming Service Bulletin 446D and 471A and Service Instruction 1409A
• Pratt and Whitney Service Bulletin 1183-U

Straight Grade Aircraft Piston Engine oils
S 100/120

Description
Castrol Aviator S piston oils are formulated from select, highly refined mineral basestocks, further enhanced by small quantities of antioxidant and pour point depressant. These oils are available in a variety of SAE grades ranging from SAE 30 to SAE 60 permitting the user to select the most suitable grade in relation to engine and environment.

Application (Always refer to engine manufacturer's guidelines)

• 4-cycle reciprocating aviation engines where use of an ashless dispersant is not required
• Break-in of 4-cycle reciprocating aviation engines (users should follow engine manufacturer’s recommendations for break-in procedure)

Features and Benefits

• Optimized formulation for break-in application
• Good low temperature fluidity for easier start-up during break in
• Fully compatible with other monograde and multigrade products approved under SAE J-1899 (MIL-L-22851D) and SAE J-1966 (MIL-L-6082E)
• Complete range of SAE viscosity grades for all climates

Approval Status

• SAE J-1966 (supersedes MIL-L-6082)
• Lycoming Specification 301G
• Teledyne Continental®MHS #24B
• Pratt and Whitney Service Bulletin 1183-U
