Exxon Mobil Elite 20W50 Aviation Oil

Aviation Oil Elite 20W-50 is a premium quality, semi-synthetic, ashless-dispersant aviation piston engine oil. It is formulated from select, highly refined mineral base oils, a polyalphaolefin synthetic base oil, and ashless performance additives providing outstanding engine cleanliness, wear protection, and corrosion protection. Aviation Oil Elite 20W-50 is designed to satisfy the requirements of all opposed piston engine manufacturer's requirements under a wide range of climatic conditions.

Features

High level of rust and corrosion protection: Extends the life of critical engine parts

Excellent wear protection: Long engine life

High oxidation and thermal stability: Minimizes deposits and extends engine life

Powerful dispersancy: Keeps engine parts, turbocharger bearings, propeller hub and dome, etc. clean of harmful sludge and varnish deposits

High Viscosity Index: Provides easy starting and fast lubrication of critical engine parts under low temperature conditions as well as high lubricant film strength and low wear under high temperature operating conditions

20W-50 Multi-grade: Year-round lubricant for most climates

Compatible with all commercial aviation piston engine oils - both non-dispersant and ashless dispersant type: Flexibility in use

Contains the Lycoming anti-wear/anti-scuffing additive: Compliance with FAA airworthiness directive AD 80-04-03-R2 par.b.1
