This was a replacement item for two gallon jugs of oil that were received earlier and had leaked significant amount of oil into the shipping boxes and packing material. These two jugs were also placed in individual plastic bags as secondary containment

PHILLIPS 66 XC AVIATION OIL 20W50 12QT CASE

In the case of 4 gal containers of Phillips 66XC 20W50 aviation oil, two containers were received with loose screw tops which resulted in significant oil leakage into the shipping container and the enclosed packing materials. Oil jugs of this size should be shipped in plastic bags to provide added protection.

I use Phillips 20W50 (opposed engines) or 25W60 (radial/antique) in my aircraft exclusively. I have had no difficulty making it to TBO using this oil. I use it year-round. That it costs less than other oils is just a plus.

PHILLIPS 66 XC AVIATION OIL 20W50 12QT CASE

Its oil, its priced right, and I can use it all year.

Ive used this oil exclusively for many years in many engines and feel its as good as oil can be. Recently tore down an engine that went 3000 SMOH (except cyls) and the crank polished out to standard as well as the cam, lifters, gears etc. I also change oil in many other conts and lycomings and it always seems the filters from engines using Phillips are usually cleaner inside.

Easy to order, arrived on time and undamaged - no problems at all

Fast and accurate delivery, well-secured with careful packaging.

Very prompt service and the response on shipping details was quick and accurate.

From ordering to receiving - great! Including all recent purchases! 5 Thanks

I like to use this oil because my Cessna 150 sits sometimes for 3 months or more. The oil guards against corrosion and my engine runs great all the time. Oil burn is very low also.

Bottles of oil in a box delivered to doorstep, quick comparable in price to driving across town.

exactly what I ordered. shipped immediately. great service.

Great price for oil and reasonable shipping costs. I recommend slipping over to Aircraft Spruce & Specialty Co. for most of your lubricating needs.

Well packed and quickly shipped.

Great product delivered in a timely period.

Shipping was on time and the product we have used for years. (We have had no problems with this product)

Excellent oil, Excellent service by Aircraft Spruce!!!

Arrived in two days - great service

Just the oil needed for frigid northern winters. Been using for 30 years. Engines consistently go beyond TBO.

The oil arrived quickly and at a great price since I purchased in bulk and got free shipping. However, one of the gallon jugs did leak out into the box but when I called the company they were more than happy to replace it.

good product

It’s Oil! Fast shipping. Thanks

Phillips X/C 20w50 is a great all-around oil for nearly any aircraft, any season. Aircraft Spruce always has a competitive price, and usually with the shipping is a better deal than others. Their service has always been fast - usually I get any item within 2 days with no extra shipping charge. Great company, great oil - cant go wrong.

I settled in this oil after some issues with other brands. It seems to do a great job of suspending the lead sludge we all get from 100LL.

I like the gallon bottles for oil change time. You get a 4 for 1 in uncapping. Its not really cheaper per ounce, but its convenient.

Perfect customer service at Corona airport

Service and delivery were great. Enjoyed doing business with you.

Product was nicely packed with no damage and came on time. As for the oil performance, that will have to be determined.

This is a good all season semi-synthetic. It was recommended by my mechanic and seems to work as advertised.

The oil is fine, but probably wont know until after a few 100 hours or so. The outstanding part was that I could just drive over to the Chandler Airport to pick it up at your warehouse there. Thanks, Mike

Switched to Phillips XC 20W50 four years ago and have never looked back on this decision.

Quick shipping. Great product.

good oil

Great service cant believe how fast it got delivered to me with standard shipping. Great product.

This was a great price, with prompt free shipment based on the amount ordered. I was surprised that rather than stick a label on each case, two cases were packed per shipping box. No problem, but be prepared to get rid of a lot of (recyclable) shipping materials.

Fast and efficient

I always get reasonable prices(usually the best price) from Aircraft Spruce and quick shipping. Great place to do business with.

Great oil, deliveried quickly.

Great price, especially if you buy enough to get the free shipping. Easy to order online and it arrived quickly.

Good Engine oil, Fair Price.

Aircraft is happy

Prompt service

Been in Aircraft Maintenance full time for 50 years. Have seen different oils come and go. This is the best oil ever for Airplane Piston Engines.

Have been running oil in my Lycoming since I’ve owned it and couldn’t be happier. The occasional leak and messy belly are the trade-offs but would definitely recommend over running no oil at all. Two thumbs up.

Good oil, good price, fast shipping

Switched to Phillips since Aeroshell stopped selling oil in 12 count cases and changed their bottles. The Phillips bottles are a much better design not to mention the oil is a lot cheaper.

Delivered on time and in good condition

Its oil. It is viscous when it is supposed to be, and less viscous when its not.

Even with shipping cost price is much better than our local distributor!

every thing was on time, and it perfect condition. thanks

I believe I ordered a single case of oil. However, two cases were shipped. Im not sure whether the extra case was a mistake taking my order, or a mistake when it was packaged. If the second case was paid for, then that is fine. Ill put it to good use. If it was shipped by mistake, please make arrangements for me to pay for it. Ive been doing business with Spruce for 20 years and this is the first time theres been an error. Stuff happens! Kim Hunter

Its sticky and makes a mess on the bottom of my airplane. They need a smart oil that turns to polished wax when it contacts painted surfaces.

Excellent oil at a reasonable price.

Use it in my own planes and recommend it to all my customers. Exceptional customer service.

I never have any trouble getting the product I want from Aircraft Spruce in a timely manner. Always arrives on time.

Highly recommended...

Meets all the requirements.

I have always used A/S in our aircrafts. Never had any issues.

This stuff is super oily.

Works great. Arrived the next day

good oil, buy the gal. size and save

I love being able to use this as break in oil instead of mineral oil and then keep clients on it.

Been using Phillips oil in my Cherokee 140 since I bought in in 1984. Been very satisfied with it.

Ran A/S 15W-50 for years. After reading and talking to various pilots and owners, I am going to make the switch in our aircraft, and if goes well, I will be stocking this for my customers.

Aircraft Spruce is always so quick to ship!! As always best prices and fast shipping!

The former owner of this aircraft used this oil and the engine runs very well. My order was filled amazingly fast, I received it the next day.

Have been using this oil for a long time and Ive always had great results with it. The cost per quart is affordable and most of the Aircraft Ive flown have used this oil with no complaints.

Like the oil... oil is oil, so cheaper is best. Aviation engines cant really take advantage of the benefits of synthetic oil unless you have a turbo-charger. The temps are low and the use period is short. Those gallon jugs wont rest upside down in my funnel though. I like to let the bottle drain for a while just to minimize the amount of oil that goes into the landfill. Its hard with the gallons.

I have used this oil for years. It is great for breaking in and for any type of operation. I dont have to switch during the winter and summer and it meets OEM specs. But its a little lower-cost doesnt hurt either.

I purchased a case of Phillips 66 x/c 20w 50 from AC Spruce and it was ground shipped. On opening the box and removing the case of oil I found that the box was saturated with oil. The case was undamaged and had never been opened. I found one Qt. container had a cross threaded cap and three others were loose. It was a real mess. You absolutely have to put labels on the outside of the shipping box saying THIS SIDE UP. Needless to say, Im going to go back to buying oil locally. The few dollars I saved didnt come close to worth it. As for the oil itself. Its Oil. It does what its supposed to.

In the case of oil, one of the lids was not completely capped and about 1/4 of the quart leaked into the box. Case was smoked and packing paper within.

On my first order of a case with Spruce it arrived having leaked in the box and on other things I had ordered. On this past order of 2 cases, all arrived clean and secure. Will continue to order. Thanks!

Went with the gallons to put fewer bottles into the trash.

Not good on salads.

Mike R Verified Purchase

PHILLIPS 66 XC AVIATION OIL 20W50 12QT CASE

Ordered 5 cases. Shipping time good. One of the cases had a quart with a loose cap, oil leaked out and made a mess.

Shipping cost would prevent me from buying again. Cheaper at the FBO.

I was a little disappointed in this purchase. The oil had been re boxed and oil was leaking from one or more of the 1 quart containers into the plastic bag used as internal packaging.

2 of 8 gallon containers were leaking causing a huge mess. I don’t have an answer to this problem because cases were sealed from factory

When I purchased my plane it had 580 hours on the engine. During an inspection, a fair amount of corrosion was found, requiring an overhaul. This is why I stick to straight weight oils and wont ever use Phillips.

There’s no foil seal or ‘lock’ ring on the cap. So two of the caps backed off and leaked oil all over the inside of the box and all over products. There needs to be SOME kind of seal on the containers.
