Phillips 66 X/C Aviation Oil 20W-50 

Is an ashless dispersant, multigrade engine oil specially formulated for year-round use in aircraft piston engines. It provides distinct performance benefits compared with single-grade engine oils, including easier starting and faster oil circulation at low temperatures, reduced warm-up time, and reduced oil consumption in most engines.

Phillips 20w50 aviation oil maintains its film strength under high loads and at high temperatures to protect against wear and piston scuffing. The ashless dispersant formulation helps minimize the formation of engine sludge, varnish, piston deposits and combustion chamber deposits, resulting in a much cleaner engine compared with the use of straight (nondispersant) mineral oils.

Phillips XC 20w50 was the first FAA-approved mineral oil-based, ashless dispersant, multiviscosity aviation engine oil. It has more than 30 years of outstanding, proven performance in a wide variety of aviation uses, including flight schools, charter and cargo airlines, acrobatic aircraft, spray planes, race planes and virtually any other general aviation application. It is available throughout the United States and is exported to other countries around the world.

Benefits

  • Ashless dispersant helps minimize engine sludge and varnish deposits for a cleaner engine
  • Easier starting and faster oil circulation at low temperatures compared with single-grade oils
  • Reduced warm-up time and cooler operating temperatures compared with single-grade oils
  • High film strength for protection against wear and piston scuffing, even under high-load conditions, such as takeoff, and at elevated operating temperatures
  • Provides cleaner and quicker break-in than traditional all-mineral, non-additized, single-grade oils
  • Protects against rust and corrosion
  • Reduces oil consumption in most engines
  • Suitable for year-round use

Application

This product is recommended for use in opposed piston engines. It can replace Commercial Grade 65, 80 or 100 single-grade engine oils with no sacrifice in performance.

This oil is recommended for use during break-in and then as the operational oil until TBO.

    Perhaps best oil after Exxon Elite vanished

    Posted by Shalom Wertsberger on Nov 20 2020

    This is a good oil for a reasonable price (from PSC, not all others). I used to use the late Exxon Elite, which truly worked great, but this is second best.

    Posted by Chuck on Mar 26 2020

    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?

    Posted by Gary Soloway on Mar 15 2020

    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.

    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.

    Aircraft Oil

    Posted by CHARLIE LAMBERT on Aug 01 2019

    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!

    Just changed over from Exxon Elite

    Posted by Jim on Oct 12 2017

    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.

    Phillips XC and Camgard now cost competitive

    Posted by Barry on Jun 14 2016

    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.
