Each bottle treats up to 16 gallons of diesel, improving lubricity to reduce engine wear and supporting consistent fuel system performance across all seasons and equipment types. ## Description Opti-Lube XPD Diesel Fuel Additive is a multi-functional formula designed to enhance the quality and performance of ultra-low sulfur diesel (ULSD). Its primary purpose is to improve lubricity, helping to reduce fuel system wear and protect critical engine components. In addition to lubricity improvement, XPD works to clean fuel injectors, support efficient combustion, and improve cetane levels by up to 3 points. It also contains a preventative anti-gel component to help maintain fuel flow in cold temperatures down to -10°F, depending on base fuel conditions. This formula does not contain harmful alcohols and is compatible with all vehicle emissions systems.Opti-Lube XPD helps maintain fuel system cleanliness while supporting engine efficiency and long-term performance. It enhances lubricity to reduce fuel system wear, supports improved fuel economy, helps increase engine power, reduces deposits and emissions, and helps prevent rust and corrosion. It cleans and maintains fuel injectors, improves fuel storage stability, supports water separation, and improves cold weather performance. XPD Formula includes a preventative anti-gel and should be added before fuel reaches its cloud point to ensure proper mixing during fueling. Performance may vary depending on fuel composition and environmental conditions. Review: The best for keeping ULSD fuel clean & it lubricates everything - 400k miles on a 2019 Powerstroke. I add a bottle with every fill up which might be overkill but the CP4 and injectors must be good bc it crancks right up daily. Be ready to change the lower fuel filter more often bc the OptiLube gets way more gunk out of your fuel making the filter more effective. I use it in my diesel SxS, John Deere tractor and Ford trucks. I’ve never had a problem with the engine on any of them after 7-8 years regardless of the temperature.
