24/7 treatment
I am so thankful for DOCs Diesel. This product is the exact products I have used in all my diesels. But the prices thru docs is so incredibly less. The filter kits I get here for my 26 ram 3500 is unreal at the dealers and you can't even get at most stores yet still
Only issue I have is the HOT SHOT product are so bad at leaking during shipping. The last 1 I just got lost nearly half during shipping. Not DOCS fault. They do what they can by wrapping the products in plastic. But it always escapes .

Doc,s 24/7
I have to use this product a little longer to give a gain evaluation, but by some strange coincidence my 2022 jeep gladiator eco diesel is getting precisely 24.7 miles per gallon. I’ll update this in the future but also I would encourage doc to formulate a 30/0. I love this truck and hope to make it last so I’ll keep using doc’s secret sauce. I also got a full filter and oil kit. everything fit perfectly thanks.

Daughter put gas in my 7.:
My daughter used my 03 f250 7.3 diesel. She put gas in it by accident. She drove it home bout 3 miles. I dumped the rest of a small bottle of docs diesel treatment in it. And changed fuel filters. Not a problem.. going on 500 miles since the “gas issue” still have not a problem
