Very impressed!
Last July I bought a 2025 ram 2500 to be set up for hot shot hauling. I quickly accumulated a lot of miles and at first the dealership didn’t even have oil or fuel filters in stock and of course none of the auto parts stores or oil change places like Valvoline carried them. Either the dealership eventually got some on stock but an oil just the oil filter cost me 89. 95, fuel filters was 250+ I could easily rack up 7K miles in three weeks so you could imagine the cost to service my pick up. Then I found docs diesel and they have my oil filter, my fuel filters, etc., for a fraction of the cost. I am very pleased and will maintain a customer for docs diesel. Not to mention the order and shipment are very easy and very prompt. I highly recommend docs diesel.
