Quick and easy order will be back to do it again
I’ve bought from them like 3-4 times every thing fits good. Had an issue w/something being damaged is shipping they sent brand new one. AA+ customer service
We’ve switched 90% of our oil filters to Docs Diesel filters and are very happy with both price and quality. Our customers love them too!
I’ve ordered several filters and have them on auto ship. It’s a great service.
I think i changed to docs not long after getting the super dog. I was using motorcraft, but decided to go with docs for the past few years.
Always get my orders fast and get what I order
I was completely satisfied with the product since the first time I tried them out, and I've always been a strict OEM customer. But when you get savings and actually a quality part to replace it at a high rate like I change my filters, it's a no brainer! Thanks guys for doing this for the little man!
Doesn't feel or look cheap, fits perfect, and came in quick!
Good value. Motor raft filter was double the price.
Working perfectly! Just like oem! Great customer service also
