Exxon Elite 20W-50 Oil

After more than three million flight hours in thousands of piston-engine aircraft, it's clear than Exxon Aviation Oil Elite 20W-50 can reduce engine wear by controlling rust and corrosion. It is an advanced blend of synthetic and mineral-based oils in a proprietary additive package to control wear. It controls rust and corrosion and offers 2x the rust protection of a competitive 15W-50 oil. Engineered to reduce wear and combat rust and corrosion in aircraft piston engines and it is suitable for recreational aircraft that typically sit on the ground for days between uses and are thus susceptible to buildup of rust and corrosion.
