ooo SYNTEQ, like Qastrol oil!
I'm not finding that as funny as you obviously are

Donaldson Endurance® lube filters are made with high performance Synteq® media. The strictly controlled processing of Synteq® media results in fibers that have a controlled size and shape, and a significantly smaller fiber diameter. This controlled processing allows Donaldson Endurance® lube filters to deliver both higher dirt holding capacity at the same pressure differential and higher efficiency compared to conventional cellulose filters. Synteq media also has better durability with usage. Over the service life of a cellulose filter, hot oil will degrade the resins that bind the media. Our Synteq media technology uses a wire screen backing that is pleated with the media for superior
strength.

At Donaldson, we have a variety of lube filter medias available to meet the most stringent of engine lube system design requirements. Donaldson engineers have a history of developing media technology that exceeds application cleanliness and service life expectations. In fact, Donaldson was the first company to introduce fully synthetic media to the engine lube market in the early 1980s. This media is now commonly adopted for extended life or enhanced engine protection needs. New lube media types are constantly under evaluation in our internal laboratories and in controlled field testing. If you have a specific application requirement, please contact Donaldson to see if there are additional media option to better suit your application.

This engine lube filter media is constructed of layered, microfiberglass synthetic fibers and is trademarked Synteq™. It provides enhanced durability for extended drain intervals while maintaining or improving efficiency and capacity. Donaldson Synteq lube media also offers lower restriction. Low restriction allows better flow which ensures component protection over a larger range of engine conditions.
The table included in that last link is kind of neat, as some of the filters are insanely efficient (like 99% @ 5 microns).
Anyways, the relevant filter for the OP is the P169071, which is 99% @ 22 microns:

Comparable efficiency-wise to the FRAM Ultra. I bought a case of them a few years back, they are excellent filters and extremely well constructed.
