Rated 5 out of 5 by from Diesel Extreme in an OM 651 (Sprinter 2500) Extreme indeed! Increased mileage, better performance. Not sure how the science of it all is working internally but it is working! Took our 2016 Mercedes Sprinter 2500 OM 651 diesel from average 28/29 on the highway to 30/31 on a trip from WA state to AZ after a recent purchase of the Diesel Extreme. Noticeable within the first 75-100 miles. The engine just "felt" smoother and power was available sooner than before we had added the Diesel Extreme. We will follow up in about roughly four thousand miles again. Great product. **Note if bottle tips over clean up quickly as the smell of Diesel Extreme is not pleasant**

Rated 5 out of 5 by from It actually works Used this on my 2014 Audi Q7 TDI and my wife's 2013 Porsche Cayenne Diesel. Neither vehicle had any problems. I use this as preventative maintenance. It does make idles smoother, starts faster and improves MPG's like it advertises. I use this every 6 months. I also use the EDT treatment with every fill-up. With the EPA choking diesel engines so much with the DEF systems and low sulfur diesel these products really help to keep the fuel system clean, reduce deposits in the DEF system and restore the gas mileage we WOULD get without all the emissions parts.

EDT and Diesel Extreme can they be mixed into diesel fuel together?

Asked by: RAL1
EDT and Diesel Extreme can be mixed together with no adverse effects whatsoever. For best results, use separately, and follow instructions on the label.
