How many bottles of fuel additive should be added each time?

Usually, the initial use requires 2 bottles, followed by 1 bottle for subsequent uses. Fuel additive usage: Fuel additives are unnecessary for new vehicles with less than 20,000 kilometers of mileage. For vehicles exceeding 20,000 kilometers, they should be added as needed, typically one small bottle per tank of fuel. Long-term use of fuel additives can be harmful to the engine. Excessive use can increase carbon deposits in the combustion chamber, and prolonged overuse may even lead to engine knocking, detonation, and worsened vehicle emissions. Precautions: New vehicles are not recommended for fuel additive use, as they have not been driven many kilometers and generally operate under good conditions, with minimal carbon deposits. Frequent use of fuel additives is not advisable, as it can lead to oil sludge, gum formation, and increased carbon deposits in the combustion chamber. Instead, additives should be used based on the vehicle's specific conditions. For severe carbon deposits, manual cleaning is still necessary. Fuel additives are not a miracle solution; vehicles with heavy carbon buildup require manual treatment, as additives cannot completely remove them. For older vehicles, the oil filter should be cleaned or replaced before adding fuel additives. Use fuel additives cautiously and rationally according to the vehicle's condition.
I've been driving for nearly 20 years and regularly use fuel additives to maintain engine health. Generally, I only add one bottle per fuel fill-up, which corresponds to a full tank size of about 40-50 liters. Never add more, as excessive use may lead to chemical buildup that could clog fuel injectors or sensors, negatively affecting performance. My own SUV gets a treatment every two months, and I've noticed smoother engine operation and about a 5% reduction in fuel consumption. For beginners, I recommend starting with half a bottle to observe your vehicle's reaction, as responses vary by car condition. Regular use helps clean carbon deposits and extends engine life, but don't expect it to fix major issues – if your car has problems, professional repair is still necessary.
