Everything fit perfect for my 2019 6.6 duramax. I’m an RV transporter so I go through a lot of filters and fluids and Doc’s seem to be very good quality at a fraction of the price of others. Overall I’m extremely satisfied with Doc’s Diesel I’ll be buying more shortly.
120 miles on the oil filter to come out to the parking lot after work to find a PUDDLE of oil under your truck! I've done 1000's of oil change in my life time and believe I was given a faulty oil filter. VERY UNHAPPY DOC! I have a pic of the MESS it left.....
Everything was as it said. It wouldn't hurt to have instruction on the fuel filter though.
So far love your filters oil jugs would be mine if they were mark with how quarts are left
Was not happy, oil filter would not stay tight/seal.
had to buy new ones. complete junk
Great product. Cheaper than parts stores. Came with all gaskets needed.
Great filters, fast shipping. No complaints here..
Everything worked perfect!!! Thanks Docs
I ordered the engine, fuel and transmission filter from here and they only deal with diesel engines. How do you send the wrong filter with the correct paperwork that has the correct filter number on it. They sent me a new filter last week but I still have not received it and had to spend more money on another engine oil filter, but they would not reimburse me for the other filter I bought but would only send me a new filter.
