Hey just curious on some other peoples opinions on K&N oil filters vs fram, motorcraft, etc. I am running a K&N on my diesel right now, getting ready to do routine maintenance on all the vehicles and just wondering: does anyone know or whats your opinion: are the k&n oil filter really worth the money? I don't personally see how they are any better. Just curious as to what kind of responses I'll get

Wix (Napa Gold), or Motorcraft FTW!

I've ran K&N oil filters in the past, they worked fine for me. They are built good, and claim they filter down to 8 micron's.. Typically I run Motorcraft oil filters on the diesel's ( same goes for fuel filters ) though.. Thats all I run period in the 6.0's.

On the gassers, I run Mobil 1 filters.. No real reason why, I just figure that they make good oil, so I bet their filters are good too.. I either run Mobil 1 synthetic, or Royal Purple. The gas engine's look flawless when doing a tear down, so thats why I stick with them.

I dont run Fram even if thats all thats in stock, I'm not a fan. Most of the time when I've ran them in the past, the check valve doesnt work. Go to pull the filter off after a cool down cycle and the filter typically doesnt have much oil to speak of in it. Not to mention I've seen too many pictures of the aftermath after they came apart.

I run a motorcraft in the summer when running rotella, but when I find mobil 1 on sale I run a Mobil 1 filter. Usually its 5 quarts and filter for $30 so I get two oil filters and a motorcraft fuel filter. Truck seems to start better in the cold with the synthetic.

I think they are worth the money. Nevertheless, I am still amazed at super duty oil filter. I purchased a
2007 Ford E-450 Super Duty Oil Filter and I was satisfied. Check car-stuff because they have reliable oil filters there. Hope this helps.

I have talk to more than one engine builder who said not to run frams. They over filter and will starve an engine for oil. How this happens when there is a bypass I don,t know. The guy who built my last drag motor said to run only K&N or Wix Racing filters on it.
