I've noticed that there is little to no information on these oil filters.I hear the pros and cons of these filters.Many motorcycle owners use these filters.I have one but I'm not putting it back on my Jeep.One company PurePower states that many companies use these filters and that the military/Nascar and others also use them.These filters also past strict FAA tests.I read that Amsoil and Fram looked at these filters from PurePower.I would think that if these filters are being used in the military and by piston aircraft and Boeing they must be safe to use.I would like to hear from PurePower and where they stand on this issue.
