The glass fibers used in the filter won't degrade over time for this old filter, so OK there. Anybody know whether the epoxy coating on the wire backing might have cracked up a bit over that much time sitting around (probably 20 years)? And the nitrile rubber ADBV might be suspect after that much time. Might cut one and see if the nitrile rubber is still flexible, and check that the epoxy coating on the metal backing looks good under a magnifying glass.

This filter was one of the first to use a fully-synthetic, depth-gradient filter element media. The idea is that the media's density increases as the oil passes through, trapping smaller and smaller particles deeper in the filter. Thus the media can hold far more particles per square inch than a conventional media (making a surface area comparison with other filters rather meaningless). The filters were manufactured by Donaldson Filtration Solutions for Old World Industries through the "Peak" brand name. Unfortunately, the filter is no longer being made. The Fram X2 filter cartridge looked similar in design to the Hard Driver, except for the cardboard end caps on the Fram. The X2 also seems to have been taken off the market. The AMSOIL EaO series of filters use this same type of media and are specifically designed for long-duration use. The only problem noted when using this filter was that the gasket had a tendency to fall out of its channel during filter installation. A little grease to hold it on solved that issue, though.
