Doc's Diesel Ford 6.7L Powerstroke 5W-40 Full Synthetic Oil + Filter Maintenance Kit 2011-2016

1st Oil Change

I usually have my 6.7 330K serviced. This time I did it myself. It was great to have all the supplies I needed. The service place usually uses T5 Rotella 15W40. I mistakenly chose 5W40 Full Sythetic. Engine is quiter and runs smoother.

Oil and filters a great

I think it's great I love being able to buy bundles the oil stayed cleaner for longer with hotshot the only problem was one bottle came delivered leaking a handful

Awesome products

I have used Docs Diesel for many years. Awesome products, great prices. The only time I’ve been disappointed with something from DD was the recent transmission filter kit, everything was great except for the transmission pan gasket, it failed to seal so I had to order a pan gasket from the local parts store and it sealed up like it should. Of course, I still highly recommend DD to everyone I talk to and will continue using you for all my diesel needs. Hoping to become a distributor to offer DD products to my customers soon.
