Diesel Deep Clean Fuel Additive Case 6 x 64oz.

The Lucas Oil Diesel Deep Clean Fuel Additive Case—6 x 64oz bottles—is a professional-grade diesel fuel system cleaner designed to restore injector performance and reduce harmful deposits in modern diesel engines. This case quantity provides excellent value for fleet operators, heavy equipment owners, and diesel enthusiasts who prioritize consistent fuel system maintenance to avoid costly downtime and performance issues.

Each 64oz bottle treats up to 25 gallons of diesel fuel, making it suitable for multiple fill-ups or extended service intervals across various vehicles. The additive effectively dissolves carbon buildup, gum, and varnish that accumulate inside fuel injectors, intake valves, and combustion chambers, thereby enhancing fuel atomization and thermal efficiency. Additionally, it offers corrosion protection for fuel system components, which is particularly beneficial in environments prone to water contamination or during extended storage periods.

This diesel fuel additive is especially advantageous for operators managing high-mileage engines, turbocharged platforms, or extreme-duty applications. It addresses common maintenance challenges such as DPF regeneration cycles that extend under heavy deposit loads and injector wear that can lead to rough idling or white exhaust. By restoring injector cleanliness, the product helps recover lost horsepower and torque while improving cold-start behavior and reducing emissions.
