Lucas engine cleaner is a chemical solvent designed to clean and remove deposits and contaminants from engines. It is formulated with a blend of solvents and detergents that can be harsh and may damage or degrade engine components such as gaskets and seals in your vehicle.
Nissan recommends using only Nissan-approved cleaning products and procedures to maintain the optimal performance of the vehicle. Using harsh or incompatible cleaners can potentially void the vehicle's warranty and cause damage to the engine and its components.
Instead of using Lucas engine cleaner, consult your vehicle's owner manual or a certified Nissan dealer/technician for recommendations on recommended cleaning products and procedures.
