The filter was dented when received. Seems to be working okay as I haven’t noticed any leaking but was a little worried about that when installing.
Great products and fantastic company
2013 ram 3500 477398 od
I decided to start servicing my 2018 Ram 2500 6.7 liter Cummins on my own. Saw a bunch of adds for Docs and decided to give them a shot. Just serviced my oil and filter, 2 fuel filters and breather filter. Parts fit perfectly and I did include in my purchase the tool for removing the oil filter without making a mess. I have to say it worked. I am happy with the products so far and the one gallon oil jugs were really easy to use with no funnel needed. I’ll be ordering and storing on the shelf the next couple of services materials to avoid the shipping time. Thanks Docs
All filters fit great and I’m excited how much better my 3rd gen runs after Docs oil
Love using Doc’s filters for maintenance on my 6.7 Cummins. Recently switched to their 15W40 oil as well and couldn’t be happier. Everything is high quality. They ship my orders quickly are great to deal with!
This is my first oil change with Doc's products. After a week of driving, my Ram sounds quieter and feels strong. I'll be back for more.
This was my second order from Doc’s. Been a great experience both times.
This was my second order from Doc’s. Been a great experience both times.
68rfe are problematic as it is so maintenance is key to keep them alive especially when towing and running the right oil and filters goes along way 2nd time using the filters and the oil still looks new for 50k service interval that I use 🔥👍
