Reviews from Real Doc's Customers

Good service and quality

I use my truck to pull 6k-12k lbs on a weekly basis putting in about 7,000 miles a month. I have been using Docs fuel, oil and air filters for a couple years now and have not had an issue. For as much as I need to do maintenance Docs is the best deal.

Love getting my filters from you guys and I checked at my local auto parts store and just the fuel filters was gonna be $100. I was able to get fuel filters the air filter and a cabin filter in the oil filter all for 109 including tax.

Perfect tool for my 2014 RAM 3500 / 6.7L Cummins. There is only a small opening in the wheel well to insert the filter sideways, and then rotate it upright to twist it into place. Not one drop of oil spilled during the removal and replacement process.
I’m glad I bought it as my sandwich baggie and rubber band innovation worked okay, but it was definitely messy. Now, no cleanup required. The photo makes the portal look ample in size, but the filter just fits, and there is no room for two hands and there is no other way to do the work.

Makes changing the oil filter a lot less messy

This is the 4th set of fuel filters I’ve put on this truck and I’ve never had any issues from them. The truck runs great, cheaper than oem filters, quick shipping and I never have to question if they fit. Docs Diesel’s will continue to have my service

I’ve been changing my own filters on the 6.7 for 13 years. Started using Docs after receiving counterfeit Motorcraft from Amazon. Nothing but good things to say about Docs. Great quality and they fit like OEM.

The filter would not fit in the housing. It was to big and in order to make it fit, it would have to be cut. Will not purchase again.

hub studs were not the right ones. They were different threads and not long enough ended up costing me more money than just buying the right hub.

This is the first time I buy Docs diesel motor oil for my truck and I’m more than happy with my purchase. Excellent quality, good delivery time and a platform easy to deal with.

Thank you dock diesel!

Tried a minimally cheaper option than ford and should have stuck with genuine parts. Canister fits as it should, the hose is short and missing the factory style angled adaptor. The canisters have a different size so you cannot swap the factory hose into this canister. Getting the hos on os a hassle and it is under tension as well as pulling at its connection point. If it fails I will be buying a genuine part. Im not a big fan of cheap Chinese parts although you do get good ones from time to time I wouldn't put this in that category. Honestly yhe few bucks more to buy genuine ford would have been well worth the time saved fighting the short hose.

I received my order reasonably quick after putting in my order. Everything was packaged nicely and it came with stickers! LOL but seriously who doesn't love stickers?! I have read plenty of good reviews about Doc's products and you can't complain about the price so I decided to give it a go. The build quality of the filter seems to be good. All the O-rings were included and in good shape. When it came time to install the filter I had a hard time getting the filter to sit in the cover... I was too far into the day and refused to put the truck back together with the old one to try another day (it's getting cold around here and the truck doesn't fit in the garage) so what I ended up doing seating the "u" part of the filter in the cover and using a clamp and some persuasive stretching of the cover on the other end to get it to seat in the cover before installing on the truck as it was impossible to get it to seat when you put the filter in first. It seem like everything is in place and seated. I haven't noticed any leaks or other issues and there is no check engine lights or service messages so I am going to take it as a win. I don't know if I'll have this truck still when the next CCV filter change is needed as I really have no practical use for a 2500 Diesel anymore but if so I'd probably give Doc's another shot.

I am on my 2nd set of oil and fuel filters from Doc’s for my 3.0 powerstroke. Prices are great and shipping is fast. I was little skeptical of the in-line filter being plastic vs the OEM one being a metal housing but I’ve had zero issues. Up until now I have always ran OEM filters on my truck and the one down on the frame rail is always hard to get off. I just did my filters over the weekend (same routine for install and removal as always) and the one from Doc’s came off with ease. Hopefully this trend continues for this process. Very pleased with their products so far, and they even sent some sweet Doc’s stickers with my order this time! 🤘🏼

Docs diesel is good shit!!!!

Dodge 2022

I’ve been ordering from Doc’s diesel since I got my first diesel truck back in 2020 and you guys have always come through. I truly appreciate it

Bolted on and hooked up perfectly
Fits my 2016

I purchased an oil filter, cabin filter and fuel filter for an '01 JLU Rubicon ecodiesel. The products arrived packaged very nice and were a perfect replacement for the OEM products. I will definitely choose Docs Diesel for my future needs.

Easy to order, quick to ship, and exactly what I was expecting. Doc’s is the BEST!!!

Honestly wasn’t expecting much but quite surprised with the quality of the filters. Will be buying from here from here on out every time I do my filters.

The issue I had wasn’t with doc it was with the shipping. When my shipment arrived it was on its side and some of the oil leaked out of one of the bottles. I did file a claim with the shipping company.

I hotshot for a living and enjoy Docs product but their shipping always takes well over a week. It’s hard to keep the kit on hand because I’m changing oil every two week. Just seems like for the premium I pay bs the $60 rotella T6 that they could do better on shipping.

Thank you doc's for always keeping my beast ready for battle.

Oh yeah this kit is perfect...just remember to position your catch can so that it actually catches your old fluid instead of just pouring it on the floor!

Top Notch products !! I’ve been using Doc’s oil and fuel filters for the past couple years, zero issues with them on my ecodiesel! I’ve used their air filters, continue to use their cabin filters, wiper blades, and diesel treatment. No reason to shop elsewhere. Get it done right the first time with Doc’s !!!
