If you accidentally overdose, you don't have to worry as long as the amount added to a tank of oil does not exceed 300ml, and continue to use it at the normal amount. On the contrary, if the dosage is too low, for example, less than 50% of the recommended amount, it can still work, but the effect is limited. 3. If you are used to adding half a tank of oil, or do not fill the tank every time, it is recommended to add a bottle. 4. 6 times is a cycle, and 12 times is a good use cycle. Due to the poor quality of some fuels, it is recommended to add a bottle before each refueling to keep the vehicle in good condition. 5. After the first addition, carbon deposits will fall off. The first 3-5 tanks of oil are the process of removing carbon deposits and decomposing colloids. After completing this process, the fuel saving effect will be more obvious. Long-term use can protect the engine. Due to the serious carbon deposits and colloid shedding of old cars, the first use may cause blocked oil circuits and abnormal engine shaking. This is a normal phenomenon. After 1-2 cycles of use, the oil circuit is cleaned and the effect is more obvious. 6. Reasons for the fault light to light up during use: ① During the cleaning process, the fuel saver will dissolve the carbon deposits in the pipe, so it may cause the fault light to light up; ② If the fault light lights up, it means that the internal carbon deposits are serious, and the fuel saver needs to be added in time for 3-5 cycles; ③ If the fault light does not light up, it means that the internal carbon deposits are not very serious, and the internal carbon deposits can be eliminated by adding fuel saver for 1-2 cycles.
