Phillips 66® Victory Diesel Aviation Oil 10W-40 is a fully synthetic multi-viscosity engine oil specifically designed for air and liquid cooled compression ignition diesel type piston aviation engines. It contains both detergents and dispersants to help keep engines clean as well as robust antiwear additives to protect engine components.

The detergent and dispersant containing formulation helps minimize the formation of engine sludge, varnish, piston deposits and combustion chamber deposits resulting in a much cleaner engine. It is specifically formulated to protect both 2-stroke and 4-stroke compression ignition aviation engines. This oil has a high viscosity index and low pour point, allowing its use over a wide temperature range. Additionally, it contains a specially balanced anti-foam additive to protect against air entrainment and foam generation.
