I have been using this product for a long time and I have to say that it is great. No complaints with it.

My problem lies with the delivery service dieselpartscanada.ca uses - namely UPS. When my wife got home she noticed that the box was leaking everywhere since it was LEFT ON ITS SIDE when the label on the box said THIS SIDE UP. So here we are with leaking bottles of additive inside and outside of the box. Also left a really strong smell that made me feel sick when unpacking the box. Not what I envisioned when ordering this product. Dieselpartscanada.ca please use a more professional delivery service. After ordering this product from you over the past three years I am considering switching to a different vendor.

This company is great! Cost effective, delivery is prompt and parts work perfectly. No complaints here

Ordered one day, received the next. Turbo arrived well packed and in new appearance, working great and solved my problem. Prepaid return label supplied, I wish all companies offered service as great as this.

Why wouldn't you buy your fuel additive from a company that actually produces fuel system components? Not only that, but if you do some research, this is the only company that's endorsed for use in GM Diesels. This stuff seems to be very very expensive where I live. So this is the best price/shipping for me. Can't go wrong. Where's my kitkat? lol

I purchased a 2011-2016 Duramax Disaster Kit with a CP3 pump the kit came with all the right items to replace the hole fuel system communication was great and very help full with any questions i had, the return core charge was applied in a timely matter
all I can say is thank you
