Has anybody tried these yet? They have a change interval listed at 25k (or one year.) The price seems reasonable...
If this has been posted before, my apoligies (searches for amsoil oil filter, return a ton of results.)
AMSOIL Ea Oil Filter
Extended Service Intervals
AMSOIL EaO Filters are guaranteed for 25,000 miles or one year, whichever comes first, when used in conjunction with AMSOIL Synthetic Motor Oil in gasoline and diesel vehicles in normal service, 15,000 miles for severe service. This coincides
with the AMSOIL 25,000-mile/one year motor oil drain interval, adding even more convenience for motorists by consolidating routine maintenance.
EaO Filters are recommended for use up to two times longer than OEM recommendations for commercial units, fleets and RVs using diesel fueled engines, not to exceed 60,000 miles for heavy-duty on-highway diesel applications.
