At how many kilometers can fuel additive be added?
3 Answers
Fuel additive can be added after exceeding 20,000 kilometers, as needed. Generally, one small bottle per tank of fuel is recommended. Functions of fuel additive: The birth of fuel additive was to address the issue of poor fuel quality. It enables gasoline to burn more completely, thereby reducing carbon deposit formation. Actual effects of fuel additive: Engine bench test reports from the China Automotive Technology and Research Center indicate that after using fuel additive, the engine's maximum net power and maximum net torque both increased by 2%, harmful emissions of carbon monoxide decreased by 40%, hydrocarbons decreased by 30%, and the engine achieved a fuel-saving rate of 2%. Therefore, qualified fuel additives do have certain effects.
Hey, as a new car owner, I think adding fuel system cleaner depends on the vehicle condition and manual recommendations. Generally speaking, it's appropriate to add it every 5,000 to 10,000 kilometers. For new cars frequently stuck in urban traffic jams with more carbon deposits, it's better to replenish around 7,500 kilometers; if you rarely drive on highways, you can delay it to 10,000 kilometers. The benefits include cleaning fuel injectors and reducing engine carbon buildup, which can save fuel and improve acceleration over long-term use. However, don't overuse it—it's not only a waste of money but may also damage parts. Remember to check your vehicle's manual first, as requirements vary by brand—safety first! Also, don't neglect regular maintenance checks to avoid regrets when major repairs are needed.
As a seasoned driver with over a decade of experience, I've found that adding fuel system cleaner every 8,000 kilometers works well. It's particularly effective during summer heat or winter cold starts—the engine responds quicker and runs smoother without odd noises. For highway-heavy driving, you can stretch it to 10,000 km intervals; for city stop-and-go traffic, topping up at 7,500 km is fine. Ignore claims about adding it every tank—too frequent use wastes money without benefits. From new car to old, I've observed that regular use slows part wear, saving repair headaches. Also, pair quality fuel with reputable additive brands (gas station options are reliable)—cheap knockoffs cause issues.
