Why Does Engine Oil Turn White in Motorcycles and How to Fix It?

If you have ever noticed that the engine oil in your motorcycle has turned white, it is not an unusual occurrence. It is a common problem that can be encountered, especially during the rainy or flood seasons.

New engine oil is typically golden yellow in color, and sometimes black, depending on the type of oil. However, the original form of engine oil is not white.

Oil mixing with water

The reason why the engine oil in your motorcycle turns white is due to the mixing of water with the oil. This can happen when water enters the engine through the breathing cavity during heavy rain or flooding. It can also occur when washing the motorcycle with high-pressure water, such as in a car wash. In such a scenario, it is advisable to avoid spraying water directly onto the engine’s sensitive parts.

Leaking oil seal

In addition, a leak in the Oil Seal Pump of the Water Coolant system in some motorcycles, such as the Kawasaki Kips, Yamaha Tzm, or Honda Nsr, can also cause the engine oil to turn white. The solution in such a case is to replace the Oil Seal.

When the engine oil turns white, it indicates that the lubricating oil has been contaminated. The function of engine oil is to protect and lubricate the engine. When contaminated, the engine can fail, the viscosity of the oil changes, and the compound content is contaminated, leading to rapid engine damage.

How to clean the engine

It is important to take immediate action when you notice that the engine oil in your motorcycle has turned white due to water contamination. To fix this problem, you can clean the engine by using gasoline. First, pour the gasoline into the engine oil hole and start the engine, allowing it to run for a few minutes.

After that, turn off the engine and remove the drain plug to drain out the contaminated oil. Once the engine looks clean and there is no more white liquid coming out, you can add new lubricant to the engine.

It is important to note that this method should be used as a temporary solution if you don’t want to overhaul the engine. It is recommended to replace the contaminated oil with new, fresh oil as soon as possible to prevent any further damage to the engine.

In conclusion,

it is crucial to be vigilant and check for any signs of water contamination or leaks in the Water Coolant system. Avoid spraying water directly onto the engine’s sensitive parts when washing your motorcycle. Proper maintenance can go a long way in ensuring your motorcycle runs smoothly.
