Will warranty be denied if fuel injector cleaner is not added?

Not adding fuel injector cleaner will not result in warranty denial. Vehicle owners can choose to add fuel injector cleaner based on their needs, as it is not mandatory. Introduction to fuel injectors: Modern automotive fuel injectors are essentially simple solenoid valves. When the electromagnetic coil is energized, it generates suction force that lifts the needle valve, opening the injection hole. Fuel is then sprayed at high speed through the annular gap between the needle valve head and the injection hole, forming a mist for better combustion. Classification of fuel injectors: Gasoline engine injectors are part of the electronic control system in gasoline engines, replacing the carburetor in carbureted gasoline engines. Automotive injectors mainly include: diesel injectors, gasoline injectors, and natural gas injectors. Some foreign manufacturers can now produce specialized hydrogen injectors.
I usually enjoy tinkering with cars. Fuel injector cleaner is mainly used to remove carbon deposits on the fuel injectors, making the fuel spray more uniform and improving combustion efficiency. If you don't use it for a long time, excessive carbon buildup can clog the fuel injectors, potentially causing engine shaking or lack of acceleration power.
Regarding warranty denial, car manufacturers typically check whether the owner has followed the maintenance recommendations in the manual. If the owner's manual explicitly states that cleaner must be added regularly and you didn't, resulting in related failures, the 4S shop might use this as grounds to deny warranty claims. However, most cars don't mandate adding cleaner, so skipping it occasionally usually won't directly lead to warranty denial.
The key is to maintain good routine maintenance records - don't neglect basic maintenance like oil changes. For safety, I recommend adding a bottle of cleaner every few maintenance cycles, especially for frequently driven cars. Preventing minor issues is much more convenient than fixing major problems and helps ensure you don't lose warranty coverage.
