Meh….
I’ve been intrigued by Doc’s, but nothing I see on their website is compelling over the OEM filters.
1) they only list the engine mounted filter as a f/w sep; but both are f/w seps when OEM.
2) no mention of micron ratings.
3) recommended 5K-10K filter change intervals. That’s a big red flag since fuel filters are more efficient the longer they run, so either their filters don’t have the same dirt holding capacity of the OEM filters or they just want more of your money.
4) They list SAE J1985 specs as their testing specs, but that’s not the standard that is used for OEM filtration. I like J1985, but it’s not used anymore. Let’s compare apples to apples.
5) lots of fancy marketing words, but I don’t see anything along the lines of “meets or exceeds OEM spec”. They guarantee fitment, but don’t mention any guarantee of filtration.
