Doc's Diesel Filters are spec'd and designed to meet or exceed the quality/performance of the original filters (OEM's) that come in your vehicle. Doc's premium grade media filter paper used on all Doc's Filters is what sets Doc's above the rest.
We wanted to go one step further in customer trust by providing,SAE J1985 3rd Party Testing of our parts.We did a full upstream and downstream efficiency testing along with a single pass efficiency test method. Our main fuel filters have been 3rd party tested, and as we get more testing we will be reporting the results.
Second time using this company and same excellent results. Plus is they offer discount to US Military.
5 stars per usual
Been using Docs exclusively. If you’re buying your filters retail your throwing cash out the window. Just as good if not better than OEM. Docs is the best. Next order I’m getting the t shirt. Keep up the good work Docs. I’m a customer for life
Good,, happy with product
So far, very good!
Haven’t used it yet. I messed up the order because I thought the oil filter was in the big box and l thought I only got one fuel filter.I should have looked in the boxes or read the labels.l am sorry I caused you trouble.I will try to get it right next time
