1, Castrol magnetic protection This oil is distributed all over synthetic engine oil. In fact, if mineral oil is used, it should be replaced every 5,000 kilometers, if semi-synthetic engine oil is used, it should be replaced every 7,000 kilometers, and if synthetic engine oil is used, it should be replaced every 10000 kilometers. If you want to upgrade to a higher level, you can use Mobil Subba 2000, although its price is relatively high, but the effect of protecting the engine is very good.
2. If you want to upgrade to another level, you can use Mobil Subba 2000. Although its price is relatively high, it has a good protective effect on the engine. Fully synthetic oil can be used at a wider temperature and has a longer service life. For the same oil film requirement, synthetic oil can be achieved with lower viscosity, while semi-synthetic oil needs higher viscosity than synthetic oil to achieve this requirement.
3. synthetic engine oil is generally used for turbocharged engines and high-end luxury cars. Synthetic engine oil is the designated engine oil for Red Bull Racing F 1, and semi-synthetic engine oil uses economical small-displacement vehicles for smooth driving.
