In many cases, damage to the engine of a Petrol Car is caused by problems with the use of engine oil. The correct use of engine oil is one of the key issues in using a Petrol Car well.
2. When using substitute oil temporarily, you need to pay more attention to it. If the oil supply is not timely or there is no suitable oil, you can temporarily use substitute oil, but you must pay attention to the oil quality and whether the oil filter is clogged during use. If the problem is discovered, stop the vehicle and deal with it promptly.
3. To choose oil with appropriate viscosity, you should choose oil with appropriate viscosity according to the local temperature. It is wrong to think that the higher the viscosity, the better. Because the viscosity is too high, the oil will flow too slowly when it is first started, which will easily aggravate the wear of the machine parts. , and even cause tile burning accidents.
4. Drain the waste oil when changing the oil. In order to extend the service life of the Petrol Car engine, drain the old oil completely when changing the oil to avoid contaminating the newly added oil, causing the new oil to deteriorate rapidly and causing the Roewe Car engine Corrosive wear. Under normal circumstances, drain the waste engine oil when the temperature is high, then add washing oil (mixed with 85% ordinary engine oil and 15% Roewe Car), run at idle speed for 10 minutes after starting, drain it again, and finally add clean new oil. Just engine oil.
5. Keep the crankcase well ventilated. The gases that rush into the crankcase from the combustion chamber are corrosive and can oxidize and deteriorate the oil and pollute the Roewe Car engine. Therefore, the crankcase must be kept well ventilated.
6. Maintain the normal oil level. When the oil level is insufficient, it will not only accelerate the deterioration of the engine oil, but also cause the burning of parts due to lack of oil. On the contrary, if the oil level is too much, the oil will flow along the gap between the cylinder wall and the piston ring. The gap escapes into the combustion chamber, causing the Roewe Car engine to burn oil. In addition, the oil level is too high, which increases the agitation resistance of the engine oil, increases fuel consumption, and intensifies wear.
7. Regularly maintain the oil filter. Check and maintain the oil filters regularly, and replace the filter element in time. The driver should be aware of this.
8. Change the oil regularly or according to the quality. After using the oil of any quality for a certain mileage, some physical and chemical indicators will change, which will cause harm to the Roewe Car engine and cause malfunctions. Therefore, it must be changed regularly according to the quality of the oil. Oil.
9. When using thickened engine oil, its oil pressure is slightly lower than that of ordinary engine oil of the same brand. Because thickened engine oil has good viscosity-temperature properties, it has a larger viscosity at high temperatures and a smaller viscosity at low temperatures. The viscosity is slightly lower within the normal temperature range of a Roewe Car engine, so a slightly lower pressure is normal.
10. When using year-round general-purpose engine oil or using thickened engine oil in winter, ordinary engine oil cannot be added to avoid affecting low-temperature starting performance; ordinary engine oil can be gradually added in spring or when general engine oil is used.
