Still have Royal Purple & Amsoil; also, Fleetguard Stratapore & Donaldson Blue (if they make them in a size you can use). More $, unfortunately...I was under the impression the Boss series would do pretty well - I’ve always thought of it has as a Mann fleece filter, as found on many Mercedes in a can rated for 15K.
Now that Fram cheapened the Ultra series - is there no “real” depth media on the automotive side of things?
