Diesel Deep Clean Fuel Additive Case 6 x 64oz.

Lucas Oil Diesel Deep Clean Fuel Additive Case—6 x 64oz bottles—is a professional-grade diesel fuel system cleaner engineered to restore injector performance and reduce harmful deposits in modern diesel engines. This case quantity offers significant value for fleet operators, heavy equipment owners, and diesel enthusiasts who rely on consistent fuel system maintenance to prevent costly downtime and performance degradation.

Each 64oz bottle treats up to 25 gallons of diesel fuel, making the six-bottle case suitable for multiple fill-ups or extended service intervals across multiple vehicles. The additive works by dissolving carbon buildup, gum, and varnish that accumulate inside fuel injectors, intake valves, and combustion chambers—areas where deposit formation directly reduces fuel atomization and thermal efficiency. By restoring injector cleanliness, the product helps recover lost horsepower and torque while improving cold-start behavior and reducing white smoke emissions. The formulation also provides corrosion protection for fuel system components, which is particularly valuable in applications subject to water contamination or extended storage periods.

This diesel fuel additive addresses real-world maintenance challenges: DPF regeneration cycles that extend under heavy deposit loads, injector wear that manifests as rough idle or white exhaust, and fuel economy loss that compounds across a fleet. Operators running high-mileage engines, turbocharged platforms, or extreme-duty cycles benefit most from regular deep-clean intervals. The case format minimizes per-treatment cost and ensures consistent supply for preventive maintenance schedules, rather than reactive injector cleaning service calls.
