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.
Ordering and delivery both went exactly as expected. Great service.

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 hasnâ€™t stopped working...must be because it is oily...
August 12, 2018
Works well in my A4M. 2K hrs +. Still going strong. Great service from ACS.

Great oil at a great price.

My A&P recommended I switch from single weight W80 to AeroShell W15W-50. So far, so good!

Oil is oil. Whats to rate? Service was very good and thats the important part.

Have used this oil in my o320 since new and now have 1600 hours on it. I do not used any additional additives. I fly often and plan for this engine to go well beyond TBO. No complaints.

What is to review? The oil is as advertised. A few strokes of the keyboard and the oil appears on my porch. Thank you Aircraft Spruce.

Ive used AeroShell 15W-50 year around in my I0470 Continental for over 13 years. Keeps my engine clean and protects against corrosion. Good stuff!

Wish these still came in 12-pack.
December 27, 2019
REALLY wish this product was still sold in a 12-bottle case. Having to order 6-packs seems to be wasteful packaging and many pilots have to order 2 cases for their oil changes.
November 15, 2019
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.
