> 5mc, what does that mean? Rhetorical question, it means, not much. Afaik, there is no published efficiency for the DW, and the AAP spec/data sheet does nothing to change that. Also the correct abbreviation for micron is um if that's what the mc is supposed to stand for. From viewing several of the AAP oil filter spec sheets, when it comes to filter efficiency, I don't find them to be authoritative.
The DW does look to be a well made filter made for AAP by some unknown manufacturer.
To the topic, I say ~5k would be ok for the DW, 3k is the sell more filters statement. As shown above in the AAP spec sheet it's OE interval rated. That said, unless the DW was part of an AAP oil/filter promo, I'd likely choose a US made Puro Classic for $3.27 everyday at Wally, just me. That and my spec size 14610 is downsized to the smaller 14612 size in the DW and according to AAP site it's everyday price of is $4.49.
As I mentioned before, the DW filter for the Benz costs 8.99. Purolator does offer the Classic filter for the Benz for 10.99. I'd spring extra for the Pureone if they offered it, but they don't.
I also happened to pick up a DW filter for free when I bought a jug of Peak Synthetic for my 96' Prelude VTEC. I did notice that the DW is about half an inch shorter than the purolator filters. Probably shouldn't run too long of an OCI with that filter.
