i use only the mopar filter made for the cummins if i didnt use that one i would get a fleetguard. thats my .02

 

I have always run Wix filters and Shell Rotella oil. Never heard anything good about fram. The bypass valve they use allows the particles that are trapped in the oil to go back through the motor.

 

The guy that works of my truck, actually showed me the technical service bullitin or whatever it was that Cummins put out, specifically saying not to use Fram. Had one on my truck first time he opened the hood, and got yelled at! Only run those that specifically say they are approved for Cummins.

 

Thanks Dr. Evil... i just put a K&N on. Ref. the fleetguard part# u provided that is for 24V.. right? THANKS for the info.

 

I run Rotella T and Wix filters but I planning on changing to cummins filter.

 

I'm running John Deere oil filters. They seem to be doing a good job, and as I can see the "behind the scene" information, they are well made.

 

Yes, Fleetguagrd LF3894 works on both the second gen 12V and 24V engines.

 

I run baldwin or fleetguard on my cummins ,baldwin or IH on my dt's and nothing but detroit on my series 60's,you can buy all four (2oil&2fuel)for the same price as one of anybody elses, and baldwin on my gassers

 

so should i change my k&n out immediatly or just do it my next oil change? i just dont want to f anything up

 

well to me I would rather be safe and buy some oil and a filter and not a motor.
