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.

Do not like the 6 quart cases and the redesigned pour spout.

I know the product to be good, but something happened to one of the bottles either before or during shipping - the cal seal had broken and oil leaked out. Fortunately both bottles were in a plastic bag and the spill was contained. Probably just a fluke though.

I have used this oil in my Lycoming E2D 0320 for 12 years and nearly 1600 hours with no issues and I do not add anything to it. I routinely change oil and Tempest filter every 40-50 hours.

Great product and arrived in good time. Shipping is a killer, though.

I have been putting this in the engine and it hasnât stopped working...must be because it is oily...

Q: Do any of the Aeroshell oils contain Camguard?

No, Aeroshell oils do not contain Camguard out of the bottle. Camguard must be added to the oil if you wish to use it.

Q: The Aeroshell 15W-50 that now comes in a red bottle, is it the same as the black bottle?

Yes, the oil is exactly the same. Aeroshell just changed their packaging from black to red.
