How do you know, can go both ways

 

Their filters are made in Taiwan and China. Nothing wrong with that if they have high quality control and meet specific standards, but with as little detail as they list on the website I have some doubt. Are most name brand filters imported now?
"Where are your filters made?
Doc’s Diesel Fuel Filters are made in Taiwan. Doc’s Air, Oil, and Cabin Air filters are made in China."

 

More and more automotive and industrial filters are coming from Mexico, still some USA production (Baldwin, a fair bit of motorcraft is USA made, some of Wix is USA made, etc)

Doc's is vague cause they are nothing but a well advertised middle man, none of the products are their design or specifications. Nothing wrong with being a pure distributor but that is all they are, a distributor with good advertising.

 

I wonder if some are still being made in Israel. Those were good filters, but thats 30 some years ago.

 

Thread Hijack!

What oil does everyone like? I have been getting mine changed at Ford, but I am all out of points and am going to go back to doing them myself like I did on my 7.3l. For a while I only used Rotella, but for a while it was almost impossible to get and then I got less picky. I got to where I was using the Tractor Supply brand. Travelers brand I think.

 

Rotella T6 for the Diesel, Valvoline or Mobil 1 for the gas. On older engines like the 4.6, I still use Castrol GTX. I stick to full synthetics for modern engines like the Ecoboost and 6.7.

 

Another vote for Rotella T6 5W-40 for the 2023 6.7L Diesel. Full synthetic in all of our vehicles, Honda/Nissan/Ford/Tracker

 

I am a heratic, running TSC travellers 15w40, cheap with a nice additive package (good slug of moly). When winter comes I will switch to Napa CK-4 10w30.

 

The only oil I've seen mixed feelings about is Rotella T6. Some have blamed it for the issues on these engines.

As far as Doc's filters is concerned, my only point is that we all know a large OE like Ford has labratories where they test Motorcraft filters for spec. Can somebody call Doc's up on the phone and ask how many of the filters in inventory he has tested with sophisticated lab equipment to ensure it meets Ford material specifications? I'm dying to hear his answer.

 

Hello? [question asked] *CLICK*

 

Basically.

He'd probably say, "Well, the Chinese vendor we source these from claims...."

So essentially no idea. This thread should have been over at post #4.

 

LOL... I blame Shell Rotella T6 for 288k miles. Where do you get this crazy stuff from.

 

I'm willing to bet he's going to claim that Shell Oil doesn't have a "testing laboratory" like Ford does, lol.

 

Yeah, Ford's customer service is sooooo much better.

 

From reading numerous threads here, on other forums, on oil websites, and on owners groups. So you got 288k miles and there are ten other guys with issues that had been running Rotella. I will believe you and ignore them.

Claim? Are you suggesting Ford Motor Company does not have labratories where they test filters, fluids, oils, etc? Get outta' here. Even you aren't that dumb.

Rotella is the cheapest oil on the shelf. I suppose that's just a coincidence, right?
