TRUSTED BY 500,000+ DIESEL OWNERS

The shop rags were an added bonus for clean up after a job well done , everything I have purchased so far has exceeded my expectations and my Chevy Silverado is one happy ride

After walking into my local auto arts store to purchase two fuel filters for my 2020 Ram 2500 just to pay just short of $240.00 I thought there must be a better way.

I had seen a few Doc’s videos and decided to give you a try. I must say my first impression was great. The selection process was easy. I found an excellent maintenance kit that had everything I needed and more, for just 30.00 more.

After researching the OEM micron requirements, I placed the order. My only wish is that it would have shipped a bit faster, but I know we are spoiled with the blue vans my wife always uses. Needless to say I am now a Docs customer for life!!

The O ring with part DF430 was too big, looked like the DF401 ring so I had to reuse the old one.

Filters fit perfectly an we’re a great price for a quality filter as long as I own a diesel ill run doc filters

truck has 190k on it. I’ve been using docs fuel filters for the past 3 years with zero issues. Love the fact that they come as a kit and make everything painless !!

Outstanding customer service, with a quality product that delivers!

The filter arrived with a tear in it and felt and looked cheaper than OEM.

Easy to use website, great products, arrived on time, everything fit. What more can you say?
Thanks, Docs.

I had to get a refund. I bought the filter/water separator combo. The water separator did not have any threads on it so you could screw it on. This is very bad quality control.

Great products oil and filter all in one order. Can’t get much easier than that.

Consistency and reliability are a big plus when it comes to ordering online, so finding a business that delivers a great experience is a win! I will be using them again.

When I went to check my Amazon filter for dirt content inside the pleat the filter came apart! Docs are 100% better when it comes to quality. I feel comfortable to run the filter longer than 50% on my filter monitor.

Packaged well and received everything I

After installing these in place of some very worn out OEM pads I'm able to say I'm quite happy with them. They installed perfectly, and I noticed an instant difference with them.
My only minor gripe is with the replacement retention clips that are provided. They felt noticeably less durable than the old OEM ones and bent out of shape very fast upon trying to install several of the pads. I ended up simply transferring the old clips over to the new pads, and everything fit flawlessly.

I appreciate the convenience of ordering everything that I need from one site and the shipping is fast.

Quality product for a decent price glad to see they have some aftermarket stuff that works well and fits like it’s supposed to definitely recommend

How outstanding parts delivery was fast? Good quality parts. Keep my old Ram running forever. Thank you

Engine running smoother, and better mpg, great product

This is the second time I’ve serviced my transmission first time with this set up from Dr. Diesel took my 45 foot horse trailer above 10,000 feet and Colorado last week transmission shifted great temperatures were down 10 to 12° and the cost of this kit as well below others

Full package as promised. Will reorder when needed

I have been using Docs filters for a while now. Came time to replace the CCV and it was a no brainer where to get it from. Check out my install video!

Works Great Fits Great Truck Breaths Great 👍

I bought the Ram 3500 after the first 10k mikes it was time for an oil change and i figured i do the filters as well, 750.00 , yeah no, i can do it myself for 250.00 and burn the old oil in my smudgepot, for heat in the back yard in the winter so, thats what we do. I can afford to pay the dealer but i cannot bring myself to pay 500 bux in labor for 45min of work.

These filters have never failed me. Been ordering them for years and always give the best protection for my 2019 2500.
