Opti-Lube XL Xtreme Lubricant Diesel Fuel Additive - 1 Gallon with Accessories (1 Hand Pump & 2 Empty 4oz Bottles) Treats up to 1,280 Gallons
Opti-Lube XL Extreme Lubricant is the Best Diesel Fuel Additive for Everyday Use.
Opti-Lube XL Xtreme Lubricant Formula Diesel Fuel Additive is a high-performance solution designed to protect, clean, and enhance modern diesel engines. Formulated specifically for ultra-low sulfur diesel (ULSD), it significantly improves fuel lubricity to reduce friction and wear on critical components like fuel pumps and injectors. By restoring lost lubrication, it supports smoother engine operation and long-term durability. Over time, deposits and residue can build up within the fuel system, reducing efficiency and performance. This advanced formula actively cleans injectors and fuel system components while preventing new deposits from forming, resulting in improved combustion, better throttle response, and reduced emissions.
In addition to its cleaning power, Opti-Lube XL provides strong protection against rust and corrosion caused by moisture and contaminants in fuel. It helps stabilize the fuel system and control water, ensuring consistent performance in all driving conditions. Users may also benefit from improved fuel economy, allowing for more efficient and cost-effective operation. Designed for year-round use and compatible with modern emission systems, this concentrated formula treats a large volume of fuel with a small dose. Regular use helps extend engine life, maintain peak performance, and keep your diesel vehicle running smoothly mile after mile.
