Oil Consumption in Vehicles During Operation - A Common Concern for Drivers

After prolonged use, oil consumption in automobiles is a normal occurrence. However, if this phenomenon happens frequently with excessive oil leakage, it will gradually cause serious damage to the engine and compromise the safety of your journey.

In this article, Huynh Chau will introduce you to the reasons why vehicle oil leaks and share some practical solutions to address this issue.

Excessive Oil Consumption Will Gradually Cause Serious Damage to the Engine

1. Why Does Your Vehicle Consume Oil Excessively?

Spark plug gaskets and cylinder head cover gaskets are the components most affected after prolonged operation. When these parts deteriorate, they lead to oil leaks and rapid oil loss. Most standard vehicles today experience this issue after extended or severe driving conditions.

After reaching the 100,000 km mark, the engine compartment heats up, causing the crankshaft seals to harden. Since they are made of high-quality material, when they become rigid, they cannot completely seal the engine oil, resulting in oil leaks and rapid oil consumption.

Many vehicle owners do not pay attention to this condition during operation, causing the gasket gaps to widen gradually, leading to increased oil leakage. Eventually, the engine oil becomes depleted and insufficient to lubricate the engine properly. This causes internal friction between components, leading to accelerated vehicle deterioration and serious damage, or even piston seizure.

Oil leakage will result in depletion and insufficient volume to lubricate the engine.

2. Consequences of Excessive Oil Consumption in Automobiles

For a vehicle to operate smoothly and quietly, the engine will gradually consume significant amounts of oil. With vehicles that have been in use for an extended period, oil consumption will be higher compared to new vehicles. However, certain contributing factors may cause engine malfunction and excessive oil consumption beyond normal levels.

Excessive oil consumption will cause serious impacts on vehicle performance, such as increased surface friction between pistons, accelerated component wear, reduced engine output power, excessive engine temperature rise affecting vehicle lifespan, and so on.

If the driver continues to allow oil to leak into the combustion chamber or outside, or allows excessive
