How Long Can a Car with Oil Burning Continue to Run?
1 Answers
When experiencing oil burning, the car can generally continue to run as long as there is sufficient oil in the engine. However, if the oil burning is severe, it is recommended to perform repairs as soon as possible, as this can both save on oil consumption and protect the components. The decision to repair an oil-burning car can be based on the severity of the issue. Normal oil consumption is typically around 0.5L per 1000 kilometers or less. If the consumption exceeds this value, repairs are necessary. Causes of oil burning in cars: 1. Valve seals: Valves are designed to prevent oil from leaking into the combustion chamber, but over time, they can wear out and age, leading to poor sealing and allowing oil to enter the combustion chamber. 2. Piston clearance: After prolonged operation, carbon deposits can form on the pistons, and wear can also occur. Over time, the piston clearance increases, making it easier for oil to enter the combustion chamber. This is why it is often recommended to switch to a higher viscosity oil as the vehicle ages. 3. Oil viscosity: If the oil viscosity is too low, oil burning can also occur. Low-viscosity oil has better fluidity, making it easier to seep into the cylinder and participate in combustion. 4. Oil quantity: If there is too much oil, the oil pressure can become excessive, forcing some oil into the cylinder and resulting in oil burning.
