Trans filters

Custom ordered transmition filters for my F250(there are 2 of them). Very expedient service. Been ordering from DPC for many years. Don't even compare prices with dillership's anymore as DPC is way chiper. Having their warehouse 10 minutes away helps too.

Your support over the years has been greatly appreciated!
worse crap ever

Causes water to gel and clogs filters, pumps and the whole system, burns dirty and has caused my DEF consumption to increase by 3 fold had to replace my DPF
, My truck was sootier than ever after using this crap ! Strongly suggest staying away from it!!

Hi Wayne, I am sorry to hear about your concerns with the Alliant Power ULTRAGUARD. I can tell you a few things that might explain some of the issues you are having. First most good additives are designed with a a water demulsifier. This helps bind together the water droplets in the fuel so that they get trapped in the fuel filter and do not get into the pump and injectors and damage them. By the sounds of it you must have a significant amount of water in your fuel. As far as the increase in black smoke this tends to happen on the first use of the ULTRAGUARD as the detergent cleans out your fuel system and burns off the soot that has built up. I hope this helps with your concerns and I would suspect by the next use of the ULTRAGUARD that you will find that you have a better running fuel system. If you have any other questions please let me know.

Fast shipping
And great products

Thanks your kind words and for your support Chris!
common rail pump measuring unit

part is installed and works as it should, however the company who delivered it should be replaced. This company is bad for your business and even canadapost would be better.

Hi Sanford, I am sorry to hear that you had issues with the courier. Can I ask what kind of problems occurred. With a little more information we can try and figure out a better alternative. I hope to hear back from you soon.
Works great

Fast shipping and the socket works great.

Thanks for your continued support Neil.

Diesel Additive Order

Thanks, great product, very fast shipping! Great vendor!!

Thanks for your support Michael!
Best price I found

I acquired a 2002 cube van with the 6.5 which turned out to have (surprise) a bad pmd. It already had the relocate kit with heat sink mounted unde the wiper cowel but it was getting heat soaked there in the day and I could hardly make it home. Having owned a 6.5 before I knew it was time to spend some money. I got a price of $510 at the dealer so I did some searching on the net. I didn’t want to go with an overseas brand, but I was sure I could save a bit. I found Diesel Parts Canada and was happy to see they were here in Alberta. After reading reviews about the speed of shipping I was happy to spend some money and get a new pmd from them. I ordered it at 3:21 on a Friday, got a shipping notification at 4:00 and it was delivered before noon Monday. Talk about service! I ended up moving the pmd to the fender so it wasn’t in the engine bay and would get some more air flow over it. The van already had an extension cable so I had lots of length. The pmd was the newer style so I shaved the curved tabs off the plug and away I went.

Hi Joe, Thanks for the update on your 6.5L! I am really glad that we were able to provide you with the OEM PMD at a competitive price, with a good turn around time to get you back on the road quickly. Thanks for your support and if there is anything else you need let us know.

Running it for 11 years

I run jet fuel in my diesel and that is a very dry fuel. I religiously put stanadyne lubricant in every tank and haven’t had a single problem with my injectors or pump. (Knock on wood)Thanks again

It's good to know that you are having such excellent success with the Stanadyne additive.


Thanks for your review Michael! Let us know if you need help with anything else.

Best Diesel additive I ever had.The difference in performance was instantly noticeable. I am still in shock over the prompt delivery of the product......doesn't happen very often these days.

Thanks for the kind words Alex! It was a pleasure doing business with you.
