My truck has more pep. I finally got around to servicing her and noticed immediately it. Not sure if it's the oil or filters or a combination of all.
I use the filter and oil kits to service my fleet of truck (4). I own a landscaping company and we are hard on our trucks, and it’s nice to have a convenient way to buy the correct amount of oil and all filters in one place.
I really like how Easy it is to order and receive my product within a week. I have ordered from Doc's twice now and will continue to do business with them. Great products and very nice prices.
Suck a great value from docs! Blows away my local retail auto parts store. Everything was great quality and the prices are amazing!
I’ve been ordering 5w 40. Found out it’s the wrong weight of oil for my truck. I live in Texas. Dodge mechanic said for our area i need to run 10w 30. My truck is a 2024 6.7 Cummins. Probably have to return my last order and reorder the right oil. I run about 10,000 miles per month. That means I need to do at least 2 changes a month. Sometimes I forget to order in time and it takes 7-10 days . Love your products just wish the transit time could be cut down. Thanks have a good day!
