Should I Use 30 or 40 Oil for Engine Oil Consumption?

[DeGarrett]

Whether to use 30 or 40 oil for engine oil consumption depends on the following situations. If the car originally uses 30 viscosity oil, then 40 viscosity oil can be used. If the car originally uses 20 viscosity oil, then 30 viscosity oil can be used. Below are some preventive measures for engine oil consumption: Use high-quality oil: Oil is highly prone to corrosion and aging under prolonged high-temperature conditions, causing the oil film to thin and more likely to enter the combustion chamber and participate in combustion. Therefore, using high-quality oil can significantly delay this phenomenon. Pay attention to the cleanliness of the fuel system: Carbon deposits are inevitably produced during the combustion of fuel, and carbon deposits are the root cause of some car problems, such as aging of valve oil seals, increased piston cylinder wall clearance, etc. These are directly or indirectly related to the formation of carbon deposits. Therefore, keeping the fuel system clean is very helpful in preventing engine oil consumption.
