★★★★★
“Doc's actually has some dang good filters, heck even their sticker pack actually comes with usable stickers that ain’t so small nobody notices them. Ordered fuel filters for my 2016 6.7 Cummins and Doc's sent updates for every step of the way, and they shipped to my house within 3 days. Cheaper than the parts store, noticeable quality, and shipped out the same day I ordered em. So overall nothing bad to say and will definitely be upgrading my fleet to all docs filters.”
TB Cattle Co
★★★★★
“I've heard good things from a lot of a different "truck-fluencers" as I like to call them, so since I own a diesel, I had to see what all the hype was about. The items I ordered shipped fast and seem to be great quality. Also love the fact that they sent 4 nice stickers along with it!”
John C.
★★★★★
“I use the filters and oil kits to service my fleet of trucks (4). I own a landscaping company and we are hard on our trucks, and it's nice to have a convenient way to buy the correct amount of oil and all filters in one place.”
Kameron C.
★★★★★
“I did my oil change with y'all's 10 W 30 full synthetic with the hot shot secret with fuel filters and immediately knew the difference and sounded better. Ran better. I was getting 20 miles to the gallon now I'm upwards of 24. Absolutely getting this for the rest of its life and my next truck's life.”
Brandon H.
★★★★★
“Easy to order, had a question got a call back very quickly and product was very nice stuff! Definitely will continue ordering my oil changes through docs 👍”
Dakota W.

“It was amazing. Everything was easy to use and very helpful having everything in one package.”
