The regular Fram filters are very poorly made. I switched to them when walmart went 90% Fram. Engine produced a good bit of "lifter" noise, the engine was starving for oil when cold.
I used about 10 of them and noticed the engine noise and didn't put it together untill I read that "mini mopar" site. Switched to a Puralator, no noise on start up, cleaner oil too. I later found I only have the start up noise with the cheap Fram filters. No noise with AC/Delco, Puralator, Motorcraft and Fleet Guard. The Motorcraft is a great filter for the money, its like the $5 to $6 + Pure One, just like the mopar sight revealed. And I can still get Motorcraft filters at Walmart for a couple bucks less than the Pure One.
I was amazed at the differance in the oil condition after 3K with the Pure One filter. My oil is not as dark now. Its doing something more than those Fram filters /forums/images/graemlins/grin.gif
Watch out for Mopar oil filters with the Cummins, I stick with the Cummins filters, the Fleet Guard brand.
