Anyone who owns an aircraft wants to take care of to the best of their ability, and don’t often like to switch products when they find something that works best for them. We get it—we all have our favorites. So when word gets out that a popular aviation piston engine oil is going to be discontinued, we understand your frustration.

We’ve had several customers reach out to us asking whether this rumor was, in fact, true, that ExxonMobil Aviation Oil Elite 20W-50 is being discontinued. Well, it is: ExxonMobil will no longer be producing Aviation Oil Elite 20W-50. We will continue to carry this product while we can, but once we run out of available stock, we won't be able to get more in. 

We know that this news affects a lot of our customers, especially those who have relied on Exxon Elite for years. While this news comes as a surprise to us, we would never leave you hanging or without proper lubrication. At Aviation Oil Outlet, we offer two equivalent products that will help keep you up in the air: Phillips66 X/C 20W-50 and Aeroshell 15W-50. Both of these products are reliable, multigrade ashless dispersant oils that will help protect your aircraft piston engine.

Phillips 66 X/C Aviation Oil 20W-50

Phillips 66 X/C Aviation Oil 20W-50 is formulated for year-round use in aircraft piston engines. It maintains its film strength under high loads and at high temperatures to protect against wear and piston scuffing. Phillips XC 20w50 was the first FAA-approved mineral oil-based, ashless dispersant, multiviscosity aviation engine oil. We recommend this product for use in opposed piston engines. It can replace Commercial Grade 65, 80 or 100 single-grade engine oils with no sacrifice in performance. It is also recommended for use during break-in and then as the operational oil until TBO.

Aeroshell W 15W-50

Aeroshell W 15W-50 is a semi-synthetic oil that provides the ultimate aircraft piston engine protection over a wide range of ambient temperatures. This product is made from a unique blend of high-quality mineral oils and synthetic base stocks combined with anti-corrosion and anti-wear additives. Additionally, Aeroshell W 15w-50 contains the Lycoming LW 16702 anti-wear additive for Lycoming engines that need improved load carrying.
