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.
