Phillips 66 Type A 120AD is a premium, single-grade oil designed for radial aircraft engines that call for SAE 60 or Commercial Grade 120 oils. It has the highest viscosity index number in the industry and lowest pour point of any single-grade aviation oil on the market. Type A 120AD has the same high-quality, ashless dispersant (AD) additive chemistry found in X/C aviation oils.
Ashless Dispersant, Single-Grade Engine Oil For Aircraft Piston Engines 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 (nondispersant) mineral oils.
Type A Aviation Oil has many years of outstanding field performance in a wide variety of aviation applications.
