Re: Oil Filters, Dissected
I ran an Amsoil EaO filter for two oil change intervals. I can't remember the precise mileage, but I'm sure it was over 16K. The second oil analysis was no worse than the first, and both were fine. Anymore, I'll just use whatever premium filter Autozone has packaged with their Castrol oil specials. It's always been either a Mobil 1 or a K&N, plus 5 quarts of oil for about 26 bucks. That's a pretty good price, and German Castrol is the oil that I now run in my 4.7L.
