Opti-Lube XPD is the best diesel fuel additive for everyday use.

Opti-Lube XPD is a proven diesel fuel additive. This additive made its mark years ago by ranking the highest in a fuel additive study. Thousands of our happy customers have switched over from other additives because it makes a difference. We have tested our product and continue to lead the market in lubricity. But that is just the beginning. XPD cleans injectors, improves cetane and contains an anti-gel to keep your fuel flowing down to -10° F. If you want to keep your diesel happy, then look no further than Opti-Lube, the number one rated additives on the market.

Opti-Lube XPD is the ultimate in performance diesel fuel additives. The best diesel fuel additive on the market.

Opti-Lube XPD’s primary purpose is to increase the lubricity properties of ultra low sulfur diesels (ULSD). However, improving Lubricity is just the beginning. XPD Formula is a multi-functional additive for upgrading the quality and enhancing the performance of diesel fuels.

XPD simultaneously improves lubricity, efficiency, cleans injectors, improves Cetane by up to 3 points and contains an anti-gel to keep your fuel flowing down to -10° F.* XPD does not contain any harmful alcohols.

Opti-Lube products protect your equipment by providing exceptional lubrication in the fuel system.

  • Increased Power

  • Improved Storage Stability (More than doubles storage life of diesel fuel)
  • Improved Water Separation

  • Compatible with all vehicle emissions systems

Don't Forget XPD Formula is a Preventative Anti-gel.

Preventative anti-gels are used before gelling occurs. To ensure a Preventative anti-gel works properly there is an important rule to keep in mind. Diesel Fuel cannot be at or below the cloud point when Preventative anti-gel is added. There are two reasons for this: (1) If the fuel is cold and wax has begun to crystallize and link, the cold flow additive will not be able to modify the crystals as designed to minimize their growth or alter their morphology, (2) Cold fuel has poor solubility, meaning proper mixing can not occur. The easiest way to ensure your preventative additive is properly mixed and your diesel is not too cold during winter months is to add it at the pump while fueling. When mixed properly the preventive anti-gel will do its job while not ‘falling out’ of solution or separating. Opti-Lube XPD and Winter contain components that interact with the wax molecules in a way that prevents them from stacking and subsequently forming large, filter plugging crystals.

Let Opti-Lube Keep Your Investment Safe From Gelling This Season.


*Dependant on base fuel and the amount of wax in the fuel. Higher doses of anti-gel may be needed in some areas.

    We've never had a CP4 fail or a pickup gel while using XPD. We use it religiously! The gallon jugs are perfect for dumping into bulk tanks.

    I have used Opti-Lube XPD with every fill of the tank and have never been disappointed in the results. I have used XPD since about 2013, and have had no issues with diesel engines in my trucks or tractors. I consistently pull heavy, and work my equipment hard, and this product keeps me from having any issues with the injection and fuel system components, and also protects me in the harsh winter months when temperatures sometimes fall below zero. Thanks, Opti-Lube, for making a great product!

    Opti-Lube XPD

    I have been using this product for 15 years or more in my 2006 Chevy 2500HD and traveling all over North America, I know my truck runs better with it in the tank. A little more pulling power, a little more fuel mileage (about 1 to 1.75 mpg depending on load) and I have found that XPD will help very poor quality fuel burn and not adversely affect motor. Yes that poor fuel will rob power and give horrible mileage but without the XPD in the tank, the motor might not have run at all. Yes, I doubled up the XPD as soon as I realized how bad the fuel was. Two tanks later, everything was back to normal. I feel that XPD saved me the cost of 2 tows due to bad fuel over the years. Like a certain credit card, never leave home without it.
