Always fast delivery, Always great products! Fuel filters, oil filters, oil, air cleaners, all of it works great!!
Great experience purchasing these products, I never got my free shirt.
Purchased the kit and first thing was it was not obvious how to take advantage of my govx discount so I didn’t get that. Then it took forever to get the kit. Like 10 days or more. I’m glad I ordered it before I had reached my mileage limit.
The kit was fine everything was there and fit okay. My other thing that I wasn’t thrilled with is seeing the made in China markings. I rather support a made in USA supplier.
It's great to order everything in a bundle
This kit had everything I needed to do my own maintenance on my truck. Saved me a good amount of money over taking it to the shop. Would definitely recommend to anyone looking to save money and get it all in one stop.
Love the products but the packaging could be better. When I received the box all of the filters were out there boxes and the gallon jubs of oil had flattened the air cab air filter. Better package would be great! Thanks guys
I order from Docs because I believe their products are superior to most and at a great price point, shipping is fast too. I might add that my local mechanic installs all my orders from Docs and he is very impressed with the quality of the filters and fluids.
All the filters were great quality. Perfect package.
Customer service is impeccable! My order packaging arrived damaged and missing 75% of the items. Docs had the problem resolved and replacement items ready to ship within 2 hrs.
This is the second time I have ordered from Doc's Diesel. I like the product but I think there's an opportunity for them to process the orders a little quicker. I wanted to change my oil and fuel filters before I left on a 4,400 mile round trip. I should have ordered sooner but I didn't think it would take 3 or 4 days before it actually shipped.
