We have been using this oil for years, it is excellent. PSC delivered fast and for a fair price.

The guys at PSC are the best! Great price, great service and very FAST delivery!

Best price around! I put it un my planes and my harley

This vendor is the best price we could find.

Delivered on time great price great service

Shipment arrived quickly, no damage.

PSC is the best! Great products at good prices with fast delivery - thank you!

Fast shipping. Priced better than my FBO. Can’t go wrong with service and delivery from Service Petroleum. Best in class!!

good lubricant

Great price and fast shipping

Great oil. Excellent fast service!

Good service from PSC.

The oil, of course, was exactly as ordered. The delivery was quick and very fast. I am very pleased with the transaction.

PSC got this case of oil out to me right away. Great job!

This is my first time doing business with Petroleum Service Company. I ordered 2 cases of Phillips 20W-50. The oil was delivered to my house in a few days , The cost, including shipping costs, was significantly less than buying from a local supplier and was conveniently delivered to my house. Prompt service and cost savings. What more can you ask for?

Product delivered as advertised.

Quick shipping, arrived in good condition and very good pricing. Can’t ask for more than that.

I won’t review the product because it is well documented as a premiere aviation oil. I use about 2 cases a year and have found Petroleum Services easy to order online from with good pricing, fast service and realistic shipping cost. I like their follow up/shipping notifications. I am not much on giving reviews, but feel it is worth my time to support a good company like PSC.

Great service, great product and a fantastic price! What else can you say?

I’ve been complaining for years about not having a convenient and reasonably priced method of obtaining my aviation oil, now I can stop griping, thanks PSC

PSC always does a great job shipping my order out fast. Product arrived as expected.

I used to run Phillips a long time ago, but had switched to Exxon Elite for better than 10 years. Now that EE is no longer available, I'm back to Phillips X/C with Camguard. Will have to see how my Lycoming likes it. PSC has the best price and shipping was prompt.

Best price

Best Price I can find anywhere. Reliable and quick delivery.

Quick shipping and a great price makes buying a case of Phillips 66 X/C 20W-50 a no-brainer!

Always impressed with the quick response and delivery. Will buy again.

I'm no expert at engine oils. The flying magazines and pilot association rags say the Phillips 66 is best, so that's what I've used for the last 15 years. Seems to be doing well. The other thing I use is Camguard Oil Additive, to enhance oil performance and resist corrosion during periods when I can't fly. I WISH PETROLEUM SERVICE WOULD STOCK THAT AS WELL, SO I CAN ORDER ALL OIL CHANGE SUPPLIES FROM A SINGLE PLACE!

My engine seems to run the best on this oil, and I use it year round in Minnesota.

I have used this oil for years in my Cessna's and am very happy with it. I have had no issues with my engines.

PSC ships fast and the price is extremely competitive.

Easy to check out the purchase on the internet. Fast service and shipping.

Good prices and quick turn around!

PSC is hands down the winter of low prices and fast delivery.

Good oil and good price and delivery.

I love this oil, and this PSC is the best place to get it. Best price and super fast shipping. Can't beat it!

This is the only place I order aircraft oil from. They always have the lowest price when you include shipping costs, and they ship extremely fast.

I have purchased this product several times from PSC and service is excellent. I always have it in a couple of days....and the price is right.

Our airplane has always used this oil. We bought more from PSC because they had the best price. It arrived more quickly than I expected.

Fast shipping, fair price and great service!

Have used this product for many years with zero problems. I always order from PSC as their prices are good, and delivery is always fast

best price I found on the internet, and the best stuff for my Continental 0-300!

Totally pleased with this lubricant. Engine continues to run normally after putting it in.

Been using Philips 20-50XC for years in plane. Never a problem. I do my own oil changes so look for suppliers providing good services and pricing. PSC meets those requirements. Fast shipping, reasonable.

Shipping was faster than the speed of light! Thanks!

Great product, great price, fast delivery.

I put this oil in my engine and it runs so smooth. Almost time for another oil change so I needed to stock up. Shipment seemed to arrive really fast too. But this is my 3rd purchase in a year and a half and I have to say that your prices continue to creep up.

Product was promptly delivered great job!

Order was delivered very quickly. Great job

Easy to order. Arrived quickly. Best price. What's not to like?

Excellent oil for my aircraft. All my oil analysis results at oil changes have been much better than average. Petroleum Service Company has the best online price and fast efficient shipping. They are now my go to dealer.

By far, the best price for this aviation oil, even after adding in the shipping cost. Fast delivery, too.

Best price for Phillips X/C aviation oil shipping was fast and affordable.

I gave them 5 stars because their website was straight forward and easy to use. They communicated the status and let me know what was happening to my order. I’m a first time buyer here and appreciate the way they do business. I’ll be back!

Product arrived on time as stated. Cost was a significant savings over other sellers! We were very pleased!!

We have two rental/training airplanes at a small airport. Since we operate on a small budget, it is important to find a good product at a great price, and this it it.

Quick ship and exactly what was ordered/expected. Thanks!

I have been using Phillips XC 20-50 as a year round oil for years in my aircraft. I stumbled upon PSC a while back and they are a very good source for this product.

Good price, quick shipping.

Friend told me about PSC. Excellent service and great price.

Found PSC by accident. Great customer service with exceptional pricing. I will become long term user of the service they provide. When you dump your oil every 25 hours I can see saving money using them for my supplier.

I've used Exxon Elite in my Tiger since 2012 when I purchased it. Based on the Aviation Consumer comparison of airplane engine oils and additives, Exxon Elite's anti-corrosion performance is similar to Phillips XC 20w-50 plus Camguard additve, and the price was lower because of high shipping charges for the Phillips oil. With Petroleum Service Company's new, more competitive shipping charges the economics have changed in favor of the Phillips oil, so I made the change. Expecting continued good service from my new oil.

Great ol, great price, timely delivery. I'm Happy!

Good service from this company, browsed for best price/delivery and found PSC to be the best.

I'm very satisfied with PSC products and service.

PSC is awesome! Cheaper and quicker than everyone else for oil. I live in the NE so this is a satisfactory hybrid that I use all year (with pre-heat in the winter). Have been using it with great success on both airplanes I currently own (PA28 and PA34)

I have used this oil for 1100 hours since the 2014 major overhaul of my IO-550-N and the Blackstone oil reports have all been excellent. Furthermore, I have made numerous purchases from PSC and have always been delighted with the reasonable prices, easy check-out and great delivery.

I haave used this product over the last 8 years and my engine has gone to TBO with no issues.

Ordering was easy, the delivery was quick, and the price was the most reasonable I could find.

I ordered two cases (cheaper shipping that way) and got them in less than a week. Price was best I could find anywhere including shipping!

I ordered 2 cases of oil for my Cirrus SR22T for half the price my mechanic was charging for oil changes. PSC shipped timely and its a great deal!

I fly a lot and want a reasonable cost multi grade oil. XC does it, no rust or we wear issues like others

0% nonsense, 100% satisfaction, at a price that can't be beat. These guys know what they are doing.

PSC offers this cheaper than anyone else. Shipping is always fast. The package always arrives clean and intact.

Exactly what my plane needed for another 50 hours of use! Shipping was fast and reasonably priced. No fuss as I needed the oil, PSC had it and after a few clicks it was at my doorstep in a couple of days. Thank you for a great experience and I hope to be a long-term customer of yours.

Fast delivery,great price!

Always get deliver in a couple days. Great value on a great product.

Very satisfied with the quick service, price and product.

Fast service...very satisfied.

You guys make ordering easy and get the product shipped right away.

Good product and quick service. I'm a satisfied customer.

Always great service from you folks..

Oil is , well, oil but service is another thing completely and PSC has it in spades. I would highly recommend your company to anyone I know that's in the market for your products.

Great price great service and delivered on time. Perfect

I have been using this oil for over 15 years with great results and if your flying 2-4 times a month or 50 hours / year or more, you don't need a more expensive oil

PSC is the best price I have found for aviation oil.

The real deal, and best price I could find online. Arrived more quickly than advertised UPS ground.

I've used this oil for years in an O360A4K. I do run 50hr oil changes with filters. Oil performs very well Summer and Winter. Fall oil change includes CamGuard. Never any issues so far in oil analysis or findings in filters.

This oil gives great performance and wear in my Beechcraft Baron

I love this product. I use it for my 1947 Indian Chief. I have totally restored the bike and engine and want to keep it clean inside as I do outside.

With PSC's new lower shipping rates and competitive price, Phillips XC 20w/50 aviation oil (plus CamGard Aviation) is now price competitive with Exxon Elite 20w/50 oil online. I've used XC in the past and it seemed to keep its viscosity longer than Elite.
