1. First of all, why add fuel treasure? Tian Jianjun of Hebei Institute of Science and Technology's paper "Analysis on the Formation and Protection of Carbon Deposition in Automobile Engine" explains that there are minerals such as paraffin and colloid in gasoline, which will accumulate at the nozzle, affecting the atomization of gasoline, resulting in insufficient combustion of gasoline and carbon deposition, which will further increase the fuel consumption of the engine and wear the parts. Fuel treasure can not only remove carbon deposits, but also inhibit their production. Liu Zhifeng, China Petroleum Lanzhou Lubricating Oil R&D Center, et al. paper "Research Progress on the Structure Composition and Mechanism of a New Generation of Gasoline Detergent" The treasure of clean fuel can also be adsorbed on the metal surface to form a protective film to reduce the generation of carbon deposits.
2. Secondly, what kind of fuel treasure should we choose? It is best not to use fuel treasure composed of polyisobutylene amine (PIBA) for direct injection vehicles. Zhang Jinlong said in the magazine "Study on the Application of Polyether Amine Gasoline Detergent" published by Guangdong Chemical Industry: "Polyisobutylene groups have high thermal stability, are not easy to decompose at high temperature, and are more likely to produce carbon deposits in some cases. There may be side effects. Therefore, PEA is more recommended for direct injection vehicles and fuel treasure. Continuous use can inhibit the generation of carbon deposit, effectively remove the existing carbon deposit, make the oil system smoother and burn more fully, and prevent engine failure and maintenance caused by carbon deposit. 3. Finally, I learned how often fuel treasure should be added for different car conditions. Using 1 time per tank of oil will naturally have a good effect, but considering the balance between effect and economy, it is recommended to use 1 time every 4 tanks of oil or about 5000 kilometers, which can still provide good vehicle performance. It is recommended to use 1 time every 2 boxes of oil or about 2500 kilometers. In the short term, the power may increase, the apparent fuel consumption first increases and then decreases, and the engine jitter first increases and then decreases.
