Stanadyne Performance Formula All Season Diesel Fuel Additive
Rick M. (Vancouver, British Columbia, Canada)
Great Product

Great price on a really good product. Delivered quickly and without issues. Stanadyne improves mileage and helps keep engine clean and running proper. I use way less DEF when I add recommended amount of this product.

So far so good

Seems to be working good so far. Only installed 2 weeks ago. Fitment was spot on. No issues with oem motorcraft fuel filter FD4596. Delivery time was reasonable considering it came across the country to Ontario. It's also a lot cheaper than Ford wanted.

Great Product

Highly recommended

It arrived faster than expected. I've been using it for years. Great stuff.

I have ordered from Diesel Parts Canada before and was impressed by their quick shipping. Same this time. The product was exactly as ordered. This is a company that responds quickly and accurately. Highly recommended.

2003-2007 6.0L Ford Glow Plug
George U. (Dartmouth, Nova Scotia, Canada)
Glow plugs

Not too happy..I could not get the glow plugs installed as I was not aware that I also needed to have harnesses as well


Great injectors for the money and the service at dieselpartscanada is second to none!


service was very prompt and professional every thing worked as it should

Satisfied Buyer

Shopped extensively for this product on-line. Wasn't going to buy a case but at way less than half the price of buying individual bottles it was a no-brainer. I live in Ontario and tried to find it on this side of the continent but prices here are just stupid. Best deals were all in western Canada (Alberta and BC). Diesel Parts Canada had the best price and a very reasonable shipping fee. Product arrived promptly in perfect condition. Well packaged and exactly as ordered. The website was easy to use and overall my buying experience was seamless and trouble free. I will certainly buy from Diesel Parts Canada again when I need something.

2014+ Cummins 6.7L Dodge Ram OE Fuel Filter
Bob P. (Kitchener, Ontario, Canada)

Very fast service! Ordered Tuesday,arrived in rural southern Ontario on Friday! Thanks.

Great product poor new bottling

The Performance Plus 1/2 gal now sells in a white opaque bottle not letting you measure the amount poured compared to the translucent bottle. The same goes for the Injector cleaner...the translucent bottles let you know an accurate amount, I wish Stanadyne can go back to the previous bottles. picture is the old bottle.


Good fast delivery, trucks is running well again.

Stanadyne Performance Formula All Season Diesel Fuel Additive
Ross C. (North Saanich, British Columbia, Canada)
Great product, shipping so so.

One of the jugs had the seal broken and some product leaked which didn’t make the courier very happy.

No T-shirt

We received this item very fast. But they didn't send the t-shirt they said they would. Very disappointed.8

Hi Dalvin,

I was reviewing your order and it doesn't look like you selected which free shirt you wanted so it was not added to the order. (It happens sometimes) Can you let me know what size of shirt you wear and I will be happy to send you one.

Great Service

Great Service fast delivery. Will order again

Great price and super fast shipping

Great service

The service with this company is excellent, I have no concern with highly recommending them.

Miss the Kitkat bar they used to insert, it was a small pleasent touch that brought a smile to my face when I open my package.

Hey Wayne,
Thanks as always for the support! We miss shipping the Kitkat bars too, but we just took a break due to the whole COVID thing.

Certified Refurbished Injector for GM Duramax 2006 6.6L LBZ
DYLAN S. (Upper Brookside, Nova Scotia, Canada)
Excellent injectors

Ordered 3 refurbished injectors and they showed up in a timely manner, came with a free t shirt!
With free shipping and price these are the best price for injectors in canada I could find.
A++ place to buy from.

Thank you Dylan for taking the time to leave a review! I'm glad we could help you out!

Alliant Power ULTRAGUARD™ Diesel Fuel Treatment
Dave C. (Guelph, Ontario, Canada)
Bye Bye Stanadyne

After testing the LubriGuard against Stanadyne the results with UltraGuard are similar. 2 to 4% better results with UltraGuard vs Stanadyne and at a lower cost per treatment. Will be full on with the Alliant products now.

GM 1994-2000 6.5L Pump Mounted Driver
Chris (Toronto, Ontario, Canada)
Great PMD, No Chocolate Bar

Lowest price around for a PMD. Didn't get a chocolate bar this time though. Kinda bummed out about that.

We are happy to offer the genuine OE PMD at a fair price. Sorry about the chocolate bar, but because of COVID we have stopped shipping them out for the time being.

They fit as promised.

The strips don't seem to be any thinner than OEM and they fit as promised. They will doo the job for several more years. I am happy with the part for the price.

Happy to have another satisfied customer. Thanks for the review Gordon!

GM 1994-2000 6.5L OEM Fuel Filter
Lorne H. (Atikokan, Ontario, Canada)
6.5 GM Diesel

This original style fuel filter is the only one that works properly. The screw on filter usually leaks out the top. Very fast delivery for this time of year.

I agree Lorne, the Stanadyne filter is the only one that gets it right on these 6.5 diesels.
