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.

Nicely packaged got my order fast.

Just as ordered and quick/shared shipping?

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.

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!

Received quickly as ordered.

delivered on time

Standard piston aviation oil of nowadays.

Have always received excellent service from Aircraft Spruce. Enjoy seeing and talking with staff at AirVenture.

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

Wish these still came in 12-pack.

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.

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

Good job

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.

Ive been using this ever since I completed break in of my overhauled O-360-A4M. So far, so good.

Excellent

Great service. oil arrived in good time.

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.

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.

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.

Good Service

Got it really fast

Standard oil of nowadays.

Thanks

Very good shipping and very convenient

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.)

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 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!

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.

Product was as described and delivered quickly.
