Diesel fuels have changed but the problems associated with diesel fuel have not. XDP Diesel Power Plus is a special formula that is compatible with all grades of diesel fuel and designed for year-round use. XDP Diesel Power Plus contains cetane and lubricity additives to protect and enhance your engine's performance. This concentrated formula treats up to 500 gallons per bottle and will not harm exhaust after-treatment systems or Diesel Particulate Filters (DPF). When looking to disperse water, improve fuel economy, lubricity, and cetane in your fuel, be sure to use Diesel Power Plus.  

The diesel fuel available at the pump is always changing in both additives and quality. One constant is the possibility for fuel to pick up water. Water in diesel fuel remains the number one fuel problem year-round. Water damages fuel 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. In addition to the removal of water, Diesel Power Plus features a corrosion inhibitor that helps protect the components in your fuel system from rust and corrosion.   

The unique formula found in Diesel Power Plus prevents damage, wear, and premature fuel pump failure. Diesel Power Plus also helps improve combustion and fuel efficiency, stabilize fuel, and prevent sludge. All of these benefits in a unique formulation which contains no harmful alcohols to attack your gaskets and seals. With your fuel system functioning at its best, you can see an improvement in fuel efficiency. Now that low sulfur and ultra-low sulfur fuels account for the vast majority of diesel fuels, lubricity has suffered.  

The national Cetane number average is 45, so the added cetane means your diesel operates more efficiently. Fuels with a higher cetane number have shorter ignition delays which provides more time for the fuel combustion process to be completed. Higher speed diesels operate more effectively with higher cetane number fuels.

Great stuff
I have used lucas, ford, standadyne, power service, hot shots diesel additive. And out of all of them the xdp works the best. They all seemed okay. But nothing ever changed as far as performance or mpg or anything i could notice. As soon as i started to use xdp, The truck ran very slightly quieter. The smoke output of the truck is cut by half i would say. The turbo seems to light quicker when 6th gear torque converter lockout is engage and i roll onto the throttle compared to before. Then after using it for multiple tanks. I got about .5 mpg more. Order #1785551

Questions and Answers

I live in tennessee - Will i need the XDP Polar D for winter or will the Diesel Power Plus Fue be fine?
View Staff Answer 

The XDP Diesel Power Plus Fuel Additive will certainly improve cold weather performance, but I’d recommend running the XDP Polar-D Winter Formula Diesel Fuel Additive once the extreme winter temperatures begin.

Diesel fuel can begin to cloud around 32ºFand gelling can begin as high as 10ºF - 15ºF (depending on fuel quality and location). Gelling of your fuel is often referred to as the CFPP (Cold Filter Plugging Point). With just 1oz of our Polar-D additive in 8 gallons of fuel you can lower the CFPP by at least 10ºF. (Add prior to filling the fuel tank to assure proper mixing)

*Keep in mind that our fuel additive is designed to help reduce the problems associated with diesel fuels in extreme temps and extend the temperature rang in which a vehicle can operate. (Fuel quality, location, and the temperature of the fuel prior to mixing can all make a difference on the additives reaction)

Is there any benefit or any harm done by exceeding the normal dose of 1oz/32 gal?
View Staff Answer 
Using more than the minimum treatment recommendation is not harmful. You can actually benefit by slightly over treating the fuel.
When it says a 5% cetane boost does that mean 5 points?
View Staff Answer 

The XDP Diesel Power Plus Fuel Additive XDDPP116 will increase cetane by 5 points.

Is it safe to use on diesel particulate filter? I have a 2015 duramax LML and don't want to void warranty
View Staff Answer 

Absolutely! – The XDP Diesel Power Plus Fuel Additive XDDPP116 is safe on all diesel engines including the newer diesel engines equipped with Diesel Particulate Filters.

Fuel additives will not and cannot void your manufactures warranty.

Do you pour both sides of the bottle into the tank or wait? Pour one side first then the other in any order?
View Staff Answer 

The XDP Diesel Power Plus Fuel Additive XDDPP116 comes in a squeeze measuring bottle. This allows you the measure just the right amount of additive without spillage or loss of product.

To use these dispensing bottles, simply loosen cap from dispensing chamber. Gently squeeze the bottle to fill measuring chamber with required amount of additive. Remove cap from dispensing chamber and easily pour the measured additive from the chamber.

(1 OZ Treats 32 Gallons of Diesel Fuel – Over treating your fuel is fine and will not harm anything)

2015 Volvo D13 Tractor - Is this product good for my application? Will it cause a warranty problem?

How long will a tank of diesel fuel stay fresh, when treated with XDP if the vehicle is not driven alot ?
View Staff Answer 

Under normal storage conditions diesel fuel can be expected to stay in a useable condition


• 12 months or longer at an ambient of 20°C/68°F.

• 6-12 months at an ambient temperature higher than 30°C/86°F.

As diesel gets older a fine sediment and gum forms in the diesel brought about by the

reaction of diesel components with oxygen from the air. The fine sediment and gum will

block fuel filters, leading to fuel starvation and the engine stopping. Frequent filter changes

are then required to keep the engine going. The gums and sediments do not burn in the

engine very well and can lead to carbon and soot deposits on injectors and other combustion


The expected life of a diesel fuel is indicated by the oxidation stability test ASTM D2274.

The test measures how much gum and sediment will be deposited after keeping the fuel at

95°C/203°F in the presence of oxygen for 16 hours. It roughly corresponds to 1 year storage at

25°C/77°F. A result of less than 20mg/L of sediment and gum after the test is considered

acceptable for normal diesel.

(XDP’s Diesel Power Plus additive provides excellent stability with a result of 1.5mg/L in the ASTM D2274 test. )

do you add the xd polar with the xdm plus or just one or other
View Staff Answer 
You do not need to add the Polar D to the Plus formula. Polar D has the same features as the Plus formula but includes added benefits for cold weather performance.
Is this additive compatible with other additives, such as Opti-Lube XL?
View Staff Answer 

Yes, our XDP DIESEL POWER PLUS FUEL ADDITIVE XDDPP116 is compatible with other fuel additives.

Is this safe to use if my Engine uses Diesel Exhaust Fluid? Is this safe to use if my Engine uses Diesel Exhaust Fluid?
View Staff Answer 
Yes! The XDP Diesel Power Plus Fuel Additive is safe to use on all diesel engines, including trucks with DEF systems. Diesel Power Plus is added to your diesel fuel and is completely unrelated to your DEF system.
