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.

Benefits include:

  • Enhanced Lubricity for Reduced Fuel System Wear
  • Improved Fuel Economy (See Diesel Power Magazine Study here)
  • Increased Power
  • Reduced Deposits
  • Reduced Emissions
  • Prevents Rust & Corrosion
  • Cleans Injectors, keeps them clean
  • Improved Storage Stability (More than doubles storage life of diesel fuel)
  • Improved Water Separation
  • Improved Cold Weather Performance
  • 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.

    Boost the XPD

    Currently mixing boost and xpd with great results. I feel i did not need as much lubrication as xpd brings alone and boost uses less additive per gallon for $$ savings. Kind of my idea of POWERSERVICE PLUS CETANE BOOSTER, but with higher quality XPD PLUS BOOST. I do average mpg slightly higher with just xpd but the mixture gives me quicker detonation during injection (performance) and more of a jerk during downshift acceleration (faster response) . Application is N57 BMW diesel.

    Awesome product

    Awesome product. Recently purchased a TDI Touareg and I must say this stuff made my engine quieter. It used to have this weird clicking noise but it doesn't have that anymore. I am quite impressed with this additive.
