Re: Oil Filter Number

I just bought a Fleetguard filter yesterday at Cummins SE and the Guy at the counter said the old number I had (LF 3894) was superseded by LF 3959. The latter number does not show up on the TSB for approved Lube Filters. What's going on? Should I take it back and search for the approved numbers?

I would take it back, the guy does not know what he is talking about. Anytime this happens to me I ask them to show me in writing. That usually straightens things out

Take that LF3959 filter back.....

. . and tell them to stick it where the sun don't shine. Altho that is a well-built filter, it was superseded by the LF3894, which has a thicker shell for the higher pressure on the 24V. He just has a bunch of LF3959's left over and is trying to pawn them off on an unsuspecting public. We know better than that!
