ChevronTexaco Aero 20W-50 Engine Oil AD
Categories:	Fluid; Lubricant
Material Notes:	Features Chevron Aero Engine Oils AD are premium quality ashless dispersant oils for four-stroke aircraft piston engines. Chevron Aero Engine Oils AD are blended with high quality, high viscosity index base oils, ashless dispersant additives, and antioxidant and antifoam agents. The ashless dispersant additives retard the formation of sludge and varnish without forming harmful ash deposits in the combustion chamber. The antioxidants resist oxidation, which causes oil thickening and corrosion. The antifoam agent is used to prevent oil foam formation, which can cause unstable oil pressure and loss of oil film strength. Chevron Aero Engine Oil AD SAE 20W-50 is a multigrade ashless dispersant oil that contains a viscosity modifier that allows for easier startups at low ambient temperatures, while retaining an SAE 50 viscosity at operating temperature. Applications Chevron Aero Engine Oils AD are recommended for use in all makes of piston aircraft engines in single and multi-engine light planes and transport-type aircraft. Chevron Aero Engine Oils AD meet all specification requirements of: Textron Lycoming Specification 301F Teledyne Continental Motors Specification MHS 24 Pratt & Whitney Service Bulletin #1183T Chevron Aero Engine Oils AD meet the requirements of SAE J1899, which has replaced MIL-L-22851D as the standard for ashless dispersant oils.
