Aeroshell Oil W 15 W 50 is a premium semi-synthetic multigrade ashless dispersant oil specifically developed for aviation piston engines. AeroShell Oil W 15 W 50 is a special blend of a high quality mineral oil and synthetic hydrocarbons with an advanced additive package that has been specifically formulated for multigrade applications.

The combination of non-metallic anti-wear additives and selected high viscosity index mineral and synthetic base oils, give exceptional stability, dispersancy and anti-foaming performance. The advanced additive package in AeroShell W 15 W 50 provides excellent protection to engines operating at extreme ambient temperatures. The ashless anti-wear additive package provides exceptional wear protection for camshafts and lifters and other wearing surfaces.

AeroShell 15W50 has become very popular amongst engine manufacturers and operators alike. In order to cater for those Lycoming engines that need improved load carrying, the Lycoming LW 16702 antiwear additive has been incorporated into the formulation thus eliminating the need for supplemental additive addition

  • Promotes Engine Cleanness. The non-ash forming, polymeric additive was developed to help eliminate the harmful combustion chamber deposits that occur during normal operation.
  • Multigrade Performance allows for improved engine operation in temperature extremes.
  • Excellent Low Temperature characteristics provide easier cold weather starting and rapid lubrication of engine parts.
  • Reduces Oil Consumption in some cases by up to 50% and resists thickening at low temperatures.
  • Protects against oil cooler plugging.
  • All Season oil function since there is no need to change from a winter / summer grade depending on the ambient temperatures.
  • High Viscosity Index Semi-Synthetic Base Oils used, maintain their viscosity and help protect engine components more effectively under the high shear stresses that an engine places on lubricants.
  • Provides Compatibility with other approved aircraft piston engine oils. Since AeroShell Oil W 15W-50 is fully approved to SAE J-1899 and is listed on the relevant Qualified Products List (QPL), elaborate precautions are not needed when changing from similarly approved aircraft engine oils, as long as these oils are qualified products.
  • Reduces Fuel Consumption by up to 5% over straight grade engine oils.

Has been used in my O-360 SMOH, oil samples look great, and oil pressure is right there at start up down to 40deg F (below that I stay home).

Good oil but Im not a fan of the new bottle. No longer can I pour straight from the bottle into the dipstick tube and have to use a funnel and carry one in the plane.

Prompt delivery and a reasonable price.

Ive been using 15w50 since I bought my PA-28 in 2002, and its been serving me well so far (including a lot of winter flying). It was convenient ordering the case of 6 from Aircraft Spruce, especially during the COVID-19 pandemic, when Im trying to minimise my face-to-face contact with people (e.g. by walking into an FBO to buy a quart of oil). Shipping wasnt too expensive, and it came quickly.
