Does KIA's Souranto diesel engine have any requirements for the quality of domestic diesel?

No, the fuel consumption of gasoline version of Hita engine is 4.4L, and that of R2.2 diesel engine is 6L. According to the quality requirements of the two engines, the price difference is about 100 yuan.

According to the different oil products in different places, the replacement mileage of diesel separators may be quite different (between 10000-25000 km). Users in areas with poor oil quality will pay more for this project;

With the increase of vehicle mileage and the arrival of major maintenance (such as secondary maintenance), the advantages of diesel vehicles will appear to make up for the disadvantages in small maintenance costs.

Extended data:

1, sulfur content exceeds the standard, resulting in corrosion of lubrication system.

Excessive sulfur content will lead to poor acceleration of oxygen sensor poisoning failure. The sulfur poisoning of three-way catalytic converter failed and the emission exceeded the standard. The chemical compound of sulfur and phosphorus blocked the three-way catalytic converter, corroded the metal parts and damaged the aluminum alloy cylinder and exhaust pipe. When sulfide enters the engine oil, it will not only greatly shorten the normal mileage of the engine oil, but also cause corrosion of the lubrication system.

2, gasoline contains water, and the oil pump is prone to failure.

Gasoline contains water, which is easy to contain during production, storage and transportation, especially the gasoline at the bottom of large oil storage tanks contains a lot of water. In addition to poor combustion, it will also lead to rust inside the metal gasoline tank. When the rust is adsorbed on the filter screen of the gasoline pump, it will increase the oil absorption resistance of the gasoline pump and reduce the power. If this situation continues for a long time, the oil pump will fail.
