[EvanAnn]

The necessary maintenance items for a Regal at 20,000 kilometers are: oil filter, fuel filter, air filter, and cabin air filter. Regular addition: Regularly add a high-quality fuel system cleaner, used once every 20,000 kilometers. It can effectively remove gum, carbon deposits, and deposits from the combustion chamber, intake and exhaust valves, fuel injectors, and fuel lines during vehicle operation, keeping all parts of the fuel system clean. It can also break down moisture in the fuel, improve fuel octane rating, and reduce harmful emissions. Regular use: Regularly use a high-quality fuel injector system cleaner and specialized equipment to clean the fuel injectors, performed once every 20,000 kilometers. This can remove carbon deposits from the injectors, eliminate engine shaking, hesitation, poor atomization, and acceleration issues. It ensures a more precise air-fuel mixture ratio, restores power, saves fuel, reduces exhaust emissions, and causes no harm to the injectors, oxygen sensors, or catalytic converters.
