Type A Aviation Oil

Ashless Dispersant, Single-Grade Engine Oil

Phillips 66®Type A Aviation Oil is an ashless dispersant, single-grade engine oil specially formulated for use in aircraft piston engines. The ashless dispersant formulation helps minimize the formation of engine sludge, varnish, piston deposits and combustion chamber deposits, resulting in a much cleaner engine compared with the use of straight (non-dispersant) mineral oils.


Features & Benefits

• Ashless dispersant helps minimize engine sludge and varnish deposits for a cleaner engine

• High film strength for protection against wear and piston scuffing

• Protects against rust and corrosion

• Formulated with the same high-quality base oils as used in Phillips 66®X/C®Aviation Oil


• Opposed piston aircraft engines that require an SAE 50 or Commercial Grade 100 engine oil (Type A 100AD)

• Radial piston aircraft engines that require an SAE 60 or Commercial Grade 120 engine oil (Type A 120AD)
