I’m confused here. My 21 fwd 2.5 came with a 15208-650e installed at the factory. I have a case of these so that’s what I used when I changed the oil early to get the break in material out. I stopped at a Nissan dealer in Chicago and they informed me that Nissan now says to use a 15208-65f1b. I’m getting conflicting info while searching the web as to whether this is actually the right filter. While the new filter is a made in Japan mahle, I noticed it seems a little lighter and doesn’t have a silicone adbv. I like oem filters, especially while under warranty and just wanna make sure this is actually correct for my application?

Hmmm. There's no supersession on the -65F0E, and the -65F1B shows up as a no-fit for gen2's. I'll check tomorrow whether DPC shows a cross ref and if there's a bulletin for it. I might need to ask upstairs to clarify. It's possible the -65F1B is about to be the new "standard filter", because it does show it as the right number for '19+ Altimas and '18+ Maximas. I know those came with -65F0E's and as far as I know, that's what Express still uses for them. So my guess is your stock filters are fine and the new p/n just means a manufacturer change.

Thanks vstar. I checked several dealer parts stores online and it shows the same thing. While I like the Mahle (made in Japan) idea over the made in Mexico (gohner) filter, the 65f0e looks to be a better filter. Silicone versus nitrile adbv is reason enough. Especially considering the 21 Altima is now saying to run the oil to 10k….which I would never do. I assume there’s a reason why Nissan up and decided to move to the mahle filter but I can’t wrap my head around why.

Like I said, probably a supplier change, but if they also changed the part specification then it will show up as a whole different part and not a supersession.

I just changed oil yesterday @5k and used this filter. Very uneventful. I still don’t like nitrile adbv but I don’t plan on running the 10k that Nissan recommends so it should be fine. The new filter is a few grams less according to my wife’s food scale. Unless I can find good reason to stick with the new filter I’m probably going back to the 65-0e for the silicone adbv on the next service. Sadly I ordered a case of the new mahle filters but it looks like I can use them on my 09 which gets oil changes based on time rather than mileage.

That sounds like a plan. I never got an answer about it, I also had the Parts guys ask DPC and they didn't know either. That makes me think the change originated in Procurement and not Engineering. If so, I doubt there will be much real difference in performance for any application that "fits in the hole".
