Reviews from Real Doc's Customers

Easy installation fits good on the truck

I was able to get everything I needed in this kit for a really good price. Saved a lot of money where normally I would have to source everything at O'Reilly's or Napa. I was very happy with this kit everything was as it should be and it made it a breeze being able to have it all shipped right to the house. I will definitely be using Doc's Diesel from now on.

I got this kit for my 2022 gladiator eco diesel. I found it to be convenient to have all the correct components delivered. All the parts were perfectly fitted to my truck and it’s no hassle to buy from doc’s. i have a subscription as a failsafe for my failing memory.

Great oil and filter combo second time running it absolutely no problems.

I have to use this product a little longer to give a gain evaluation, but by some strange coincidence my 2022 jeep gladiator eco diesel is getting precisely 24.7 miles per gallon. I’ll update this in the future but also I would encourage doc to formulate a 30/0. I love this truck and hope to make it last so I’ll keep using doc’s secret sauce. I also got a full filter and oil kit. everything fit perfectly thanks.

I have been using Doc since I first bought my truck and have never looked back!! The only thing missing is a Doc Diesel beanie!!! I don’t wear ball caps just Beanies!lol!

Worked great once again. Fast shipping. Exact sizes I needed

ordered oil, filters, and fuel filters. Called because I thought I had the wrong oil filters, and someone called me back. a real person. This was for an F-350, 2026

Great product that was as described. I will be purchasing from Doc's diesel again the shipping was fast and the website was easy to use.

Another home run from Doc’s. A quality, fair priced filter kit. Two fuel filters and one oil filter with o-rings for the Cummins 6.7 A convenient solution for today’s diesel trucks. Mine in particular. lol. Thanks y’all

Doc's is great to deal with even with their recent move to the new facility the order was fast and on time. Great service and products are priced comparable to others yet the quality is much better.

Fast, easy, and reliable service and parts make Doc's Diesel the best company around. Hands down.

Just got them on the truck everything bolted on like it should they look great. First day put on some heavy miles with heavy loads and truck feels awesome . Will be posting an install vid on my youtube! Subscribe and check it out thanks.

CCV filter doesn’t fit correctly into the cover and caused my cover to break tabs off and strip threaded inserts out because the cover wouldn’t sit flush. I’ve used Doc’s for lots of fuel filters for the last couple years but this is my first CCV filter from them and this has me questioning whether or not I’ll ever use them again.

First time I've used Docs Diesel oil, filter, cabin filter. So far so good. There is no tick that'd you commonly hear with other oils and the cabin filter thick heavy duty. I will buy again. Ive been using the def guard for couple months now and I think it helps

I can only speak to the Doc’s oil filter from a visual perspective because I haven’t installed any yet. The only difference is that the Doc’s filter is about a 1/4” shorter than the Motorcraft filter. I change my oil and filter before the recommended intervals so this does not concern me.

Perfect fit. Was worried about throwing a code not being OEM, but everything was fine. A little disappointed in how long it took to receive them, but it ended up working with my schedule.

First time ordering through Doc’s. Ordered two of the 6.7 Powerstroke filter kits, plus extra oil filters. Every filter fits like OEM filters. When you place Doc’s oil filter next to a Motorcraft oil filter the Doc’s filter is a bit smaller, maybe a 1/4” difference. But the price reflects it and I change my oil at shorter intervals than recommended so I'm not overly concerned out a little less filtration.
It's nice to find everything for servicing your truck in stock at one location.

This is my new favourite hoodie (I have a lot of hoodies) but the design is spot on, love the clean look. And it’s insanely comfy and fits perfect in a size large. Thanks Docs Diesel!

good quality, complete kit, good shipping. Good Price. awesome .

Fit and finish is great. No complaints from me.

This filter did not work on my truck and the hose was pre set in the wrong direction. Once I installed the hose it had a 90 degree bend restricting air flow. Prior to installing your filter be sure your hose is set to the right direction or it will have a sharp 90 degree bend. If the hose swiveled it wouldn't of done this but none of the hoses swivel on any of the CCV filters. It was probably just a bad one in many that are sent out but this is the reason for a one star rating. I just want people to be aware of this before install so you don't have to waist time installing it if your CCV has the hose set to the wrong direction. As you can see in the photos below the hose is not set to the correct direction and you have to bend the hose from the left side to the right. I had ordered fuel filters with this order and those fit great.

Great filters

Just installed my first order from Doc's. Fuel filters and CCV filter. Everything fit as they should and appear to be good quality.

Since i started using Docs filters, it's had become cheaper, easier and better for my ole truck. Order, wait, receive. install that easy l
