Phillips 66 X/C Aviation Oil 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. It 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.
X/C Aviation Oil 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.
Excellent oil at a reasonable price.
Use it in my own planes and recommend it to all my customers. Exceptional customer service.
2 of 8 gallon containers were leaking causing a huge mess. I donâ€™t have an answer to this problem because cases were sealed from factory
I never have any trouble getting the product I want from Aircraft Spruce in a timely manner. Always arrives on time.
Meets all the requirements.
I have always used A/S in our aircrafts. Never had any issues.
This stuff is super oily.
Per the supplier: We have not heard of XTC. Phillips oil does not have an XTC version, only X/C.

For example, the code on the bottle will be formatted like this LL41A24017. To read the manufacture date, the first 5 characters are irrelevant. So, in this case, the date comes from 24017. To read it, it is the 240th day of the year 2017. If the code was LL41A00118, that would be manufactured January 1st, 2018. According to Phillips tech support, there is set shelf life for this oil as long as it is stored properly. After 5 years, they recommend the oil be retested prior to use.
It does not but it can be added to it.
