XDP knows diesel and has wanted to offer a fuel additive for some time. Finally, after a lengthy R&D process, we are proud to present our specially formulated concentrate for the best year round use in your diesel truck. Running XDP Diesel Power Plus in our own trucks through development gives you the confidence in knowing it's now ready for the masses and is the only diesel fuel additive for your investment.

Diesel fuels have changed but the problems associated with diesel fuel equipment have not.

The diesel fuel we buy is always changing in both chemical content and quality. One constant is the propensity for diesel fuel to pick up water.  Water in diesel fuel remains the number one fuel problem year round. Now that low sulfur and ultra low sulfur fuels account for the vast majority of diesel fuels used today, water is now a bigger problem than ever before.  Water damages injectors, scores pintles, creates gum and varnish, interferes with fuel combustion and harbors microbes and fungi. Diesel Power Plus contains the most effective combination of ingredients to absorb water from fuel. The unique solution prevents damage, wear and premature fuel pump failure. Diesel Power Plus also helps improve combustion and mileage, stabilizes fuel, and prevents sludge. All of these benefits in a unique formulation which contains no harmful alcohols to attack your gaskets and seals. Our concentrated formula treats 500 gallons with only ounces.

The PLUS is a 5% Cetane Increase

What is Cetane?
Generally, diesel engines run well with a Cetane Number (CN) from 40 to 55. Fuels with a higher cetane number which have shorter ignition delays provide more time for the fuel combustion process to be completed. Hence, higher speed diesels operate more effectively with higher cetane number fuels. The national CN average is 45.

I have tried other fuel additives on my 2016 Duramax but all I can say is wow. I fueled up yesterday and used this product for the first time. After about 100 miles I could already tell this product has begun to work. Truck idles much smoother. MPG jumped significantly, I have been averaging 16.5mpg and over the past 100-150 miles up to 18mpg. Also, have noticed a little more pep when I mash the throttle. This product does exactly as it says it should which most others do not. I will never be without it. 1oz per tank where others are an entire bottle for more money than XDP's.

My 2000 F250 went from 17 mpg to 18 mpg when I started using XDDPP. I just ordered DPP for the third time. When furl was $4 per gallon, one bottle saved me $90 through improved fuel economy. Now that fuel is down to around $2 it only saves $40 per bottle. My order of 12 will save me about $500.
Very surprised

I'm not a believer in fuel additives. I've numerous different kinds and have always experienced the results, they don't work. I drive class 8 truck for a living and I own my own rig, so I've put the miles on testing different products, and haven't found one that was any good.... Until now! I bought this product with the same expectations as the rest, I thought I would give it a try due to xdp being a good company to work with. The first fill up I treated per instructions on the bottle (1oz to 30 gallons) and I was amazed to see resultson the first tank! I picked up .7 miles to gallon had a smoother idle and a lower fuel temp! The reason I say lower fuel temp is because the ecm has a cooling plate the back side of it which fuel runs through, when it would get hot outside the cruise control would stop working due to the ecm getting to hot, about half way into that first tank full I noticed the cruise working much better and setting when I wanted to set it! It was 93 degrees that day. I was amazed. I'm still using the product and will continue to use and have been ordering in bulk. I highly recommend this product to everyone. I've ran the other products and they don't work, but this simply does!! Truck has a n14 Cummins celect plus @ 525hp.
