Stanadyne Performance Formula - it does make a difference!

I purchased the product for my 2016 Ram Ecodiesel. I've been running it for 2 years now and can report that the product is amazing. It provides consistent gas mileage despite the weather conditions.The engine runs smoother and is cleaner with the product. Last time I took the truck in for an oil change the mechanic came out to ask me if I had just cleaned the engine or if I had recently got an oil change as it looked so clean.
The number 1 reason I purchased this product was for a known flaw with the EGR in this Ecodiesel. Due to the recirculation, a build up of burnt oil substance can build up on the EGR. This requires a thorough cleaning every 20-30k or the risk of engine failure looms. I can report that while the problem is not eliminated completely, it's improved drastically. I've just passed the threshold of 30k since last looking at the EGR and it looks like it was just cleaned! I am thoroughly impressed by this product and the German reviews I read prior to using it are 100% accurate.
Highly recommend for your diesel engine for around $7/tank. Diesel Parts Canada the best place to buy. Quick shipping, well packaged, reasonable price.

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.

Can I use your injector cleaner in conjunction with the All season conditioner

Highly Recommended

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.

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.
