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.
Great oil indeed. Whats even better is, as I live in the same state as one of Spruces distribution centers, and delivery is extremely fast.

I have been using Aeroshell Aviation Oil 15w-50 Multigrade for many years in my PA 28-160. Currently have over 1300 hours SMOH and going strong!
November 6, 2020
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).

I got an email asking me to review my recent purchase, so here it is:
Its oil, exactly as advertised.
(Im not sure what else to write.)

Got it really fast
July 6, 2020
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.
June 22, 2020
Prompt delivery and a reasonable price.
June 22, 2020
Seems to keep engine from making metal.

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.

I have used this product for years now and my engine is running well. The multiviscosity oil allows easier starts in cold weather and I believe that save the engine a lot of stress.

Have always received excellent service from Aircraft Spruce. Enjoy seeing and talking with staff at AirVenture.
October 10, 2019
Nicely packaged got my order fast.
May 12, 2019
Just as ordered and quick/shared shipping?
February 18, 2019
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.
December 13, 2018
Great product and arrived in good time. Shipping is a killer, though.
October 14, 2018
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.
July 16, 2018
Great oil at a great price.
November 29, 2017
My A&P recommended I switch from single weight W80 to AeroShell W15W-50. So far, so good!
November 16, 2017
Oil is oil. Whats to rate? Service was very good and thats the important part.
October 30, 2017
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.
August 26, 2017
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.
March 24, 2017
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!
March 6, 2017
Arrived promptly, as scheduled. This is an excellent product, but it is (overall in the marketplace everywhere, not just your site) OVERPRICED. Usual good service correct order from Aircraft Spruce.
May 23, 2020
Ive been using this ever since I completed break in of my overhauled O-360-A4M. So far, so good.
March 31, 2020
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
Great Engine Oil. High Price. I really miss the 12 quart case. Crude oil is lowest in recent history yet this oil is the highest price in history.
November 6, 2020
Do not like the 6 quart cases and the redesigned pour spout.
September 27, 2019
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.
