âDoc's actually has some dang good filters, heck even their sticker pack actually comes with usable stickers that ainât 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.â

âI 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.â
Brandon H.âI 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.â
