I'm sure it has been asked and answered many times, but I could not find anywhere when I searched for it.

What oil filters - Mobil 1, WIX, Pure One, etc. - fit the 6.2's? I have the Merc filter number... is there a cross reference anywhere?

I can find plenty of info for 496 and 525 but nothing on the 6.2. Maybe it's the same?

I use the Wix 51069

I don't think the Merc filters are any different from big block to smallblock.
I use the 51060 Wix on my bigblock

This might help:

Notes:
Mobil suggests this company if you need to order a hard to find oil filter.

Purolator Pure One PL36461 has a silicone anti-drain back to keep oil in the filter for those mounted upside down.

Wix 51086 (NAPA Gold 1086) will also work. I buy mine here --> www.fleetfilter.com

wow, that should about cover it! lol
