Maintenance items are definitely not a place that I'd try to save some money. There are reputable online sites where you can get OEM filters for nearly the same price as docs. Just do some searching on this forum and you'll find them.

Agree 100%. Everything on a diesel engine is $$$$. Buy OE filters.

I get mine from dieselfiltersonline.com and they have great prices.

Its a personal thing,... I get it. But its no different than someone using Fram, NAPA, WIX, etc. Normally in the aftermarket, replacement parts are to "meet or exceed" oem specs. My question was if any one has dealt with this place.....not the OEM vs aftermarket argument.

Jim - I'll catch flak for this, but my Dad uses them still, and he has since he bought his 2018 new. They're retired and travel/camp on a regular basis. He's never had a filter failure and the quality is like you mentioned, as good or better. I'm in the private label business and I can attest, our national brand is the same as our private brand. We just charge more for the national brand and throw some marketing behind it. We make more $$ on the private brand because customers use their own $$ to market or promote it. You're right, if they make claims that meet the minimum filtration needs, they are probably good to go, Motorcraft, Fram Ultra, K&N, Wix...all do the job they're intended to do. I think Doc's is factory spec or better.

I am, I avoid non prime ones, and check the pictures carefully, there are tell tales on non OEM filters. So far all filters have been true OEM.

Doc's is all rebranded PTC products....

https://ptcauto.com/products/filters/

The website and story is adorable (eyeroll) and all however they are just reselling someone else's product at high volume to get to the low price. Nothing special but I have heard good things about their shipping. I emailed them about the water separator specs on their 6.7 fuel filter kit, the customer service rep could not answer the question so they lost me there.

Looks like Doc's fuel filter set is $44 and Ford OE is $72 (dieselfiltersonline.com) so the difference is like $28 bucks. I'm doing fuel filters every 20,000 miles which is 18 months or a little more for me, so I can handle $28 bucks in almost two years. Plus if I ever have a warranty issue I can show that Motorcraft filters have been going into my truck.

It almost sounds as if the price were better than a $28 difference you wouldn't choose Motorcraft then lol. And if its a "warranty issue" most filters that meet or exceed factory requirements will not be held responsible.

How many microns is a motorcraft fuel filter?
This element collects particles larger than 10 microns. The smaller, secondary fuel filter is located on the engine next to the oil filter housing and is designed to capture particles larger than 4 microns.

Doc's Diesel fuel filters have a micron rating of 3 and a 99.7% efficiency rating. The micron rating refers to the size of the filter's pores, and filters with a lower rating remove more contaminants than those with a higher rating.

From Doc's web page:DOCS' DIESEL FUEL FILTER / WATER SEPARATOR:

Doc’s Diesel Fuel Filters are designed with high performance cellulose glass media that traps contaminants such as rust, dirt, debris, and harmful contaminants. New vehicle warranties stay in effect when Doc's Diesel filters are installed correctly and according to engine manufacturer's recommendations.

I'm not representing Doc's at all, but the numbers say it all.........The Motorcraft brand is fine and so are the stock cheap shock absorbers that come on these trucks when new, but the aftermarket can offer an improvement. There are tons of enhancements out there for these trucks and most of it is better than OEM.

That is lovely verbal popcorn but doesn't state at what efficiency under SAE J1488 (or any under applicable standard) that water is being stripped from the fuel system, much less specify whether that efficiency is for free or emulsified water. To be fair to Doc's, motorcraft, purolator, STP, champion, etc etc don't provide that information readily to the consumer either. Sometimes you get it in snippets here and there. Other brands, such as Baldwin, Donaldson and Wix do or if you inquire they will provide that information.

Truth be told, I doubt PTC products would cause any issue and there are 6.7's out there running PTC products in one flavor or another. Not really worth it to me but that is a personal choice of course.

I get all that. My question I guess would be, how do you know? Who tests those? Has a third party tested them and confirmed Doc's claims? Who makes those filters? Is the media the same quality as OE?

I mean, I could open an online store tonight and start selling second hand filters just like Doc does and I could put any claim I want to on there. I could rate my filters to 2 micron. How are you going to know one way or the other?

With huge OE names, you can bet they test these filters themselves in lab settings. They have a lot on the line so they have incentive to do it, and they have the money and resources to do it. So a genuine OE filter is sure to be trusted.

That's not to say Doc's filters aren't what he claims. All I'm saying is, how do you know?
