Opti-Lube XPD is the Best Diesel Fuel Additive for Everyday Use.

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.
