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.
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
