At present, developed countries have proposed that the latest specifications are GF-3 and PC-9, and their appearance will accelerate this change. In the future, the third base oil will dominate the engine oil and automatic transmission fluid. GF-3 requires a high viscosity index, a low volatility, and a low cold-starting viscosity with constant viscosity. Only high-quality Diers (commonly referred to as "half") and No. 3 base oils can meet the requirements of GF-3, but the cost of blending CF-3 with the No. 3 base oil is higher. At present, the lube oil market in Europe and the United States has become saturated. In recent years, the growth of lube oil production has been slow. It has basically hovered around 40 Mt per year, and some countries have declined. The quality of lubricating oil products has been greatly improved, and the service life is getting longer and longer. In particular, the replacement of internal combustion engine oils is fast, and it takes about four years to replace them. With regard to the proposal for the development of China's lubricant base oil, along with the development of China's economy, the demand for lubricants is increasing. It is expected that the base oil produced by the hydrogenation process will be the direction of development in the 21st century and can basically meet the market demand.
