Phillips 66 Aviation offers X/C aviation oil (available in SAE 20W-50 and 25W-60), an ashless dispersant, multigrade engine oil specifically formulated for year-round use in aircraft piston engines. Use of Phillips 66 X/C provides easier starting and faster oil circulation, reduced warm-up time and cooler operating temperatures, compared to single-grade oils. This oil has high film strength for protection against wear and piston scuffing, even under high-load conditions, such as takeoff and at elevated operating temperatures. It provides cleaner and quicker break-in than traditional all-mineral, non-additized single-grade oils. It protects against rust and corrosion and reduces oil consumption in most engines.
