Cataclean Exhaust & Fuel System Cleaner (5 Liter)

Sized for trucks, fleet vehicles, and industrial equipment, this 5-liter Cataclean bottle handles the larger fuel tanks and heavier carbon loads that come with bigger engines and commercial use. It is the same patented, EPA-approved Cataclean formula scaled up for applications where the standard 16 oz bottle would not be enough.

Cataclean reduces carbon buildup across the entire fuel and exhaust system, cleaning catalytic converters, oxygen sensors, fuel injectors, cylinder heads, and diesel particulate filters. Independent emissions testing has shown the formula reduces total hydrocarbon emissions by up to 50 percent. Unlike the standard consumer bottles, this 5-liter size is compatible with gasoline, diesel, and hybrid engines, so it covers the full range of powertrains found in mixed fleets.

Application follows the same approach as the smaller bottles: add the appropriate amount to the fuel tank and drive. The product does not alter fuel composition and is safe for catalytic converters, oxygen sensors, and DPF systems. For fleet maintenance programs, regular quarterly treatments help keep emissions equipment functioning properly and can reduce the risk of costly catalytic converter or DPF replacements down the road.
