5 Misconceptions About Engine Oil

Engine oil is best known for its lubrication and cooling functions while the vehicle is in operation. As a result, the vehicle can operate at high efficiency in harsh environments while ensuring the engine is protected from friction and overheating.

Despite the important role that engine oil plays in motorcycles, many people still hold misconceptions about it. Here are five common misconceptions we often encounter!

Oil lubricates and cools the engine

1. The "W" designation in oil codes represents "weight"

The "W" designation in oil codes is often misunderstood.

When choosing engine oil, viscosity specifications are particularly important to consumers. However, most consumers believe that the "W" in the oil code indicates whether the oil is thin or thick. This information is not entirely accurate, as these numbers indicate the oil's thickness; the larger the number, the thicker the oil.

Specifically, the "W" stands for "Winter," indicating the oil's ability to start in cold weather. The number before the "W" corresponds to the viscosity rating for cold weather conditions.

The number following the "W" indicates the viscosity rating for hot weather conditions. As this number increases, the oil becomes thicker. Additionally, a larger number after the "W" means that the oil will flow more slowly through the engine gaps during operation.

2. Oil should be changed every 1500 - 2000 km

Regular oil changes help protect the engine.

Oil and engine technology have advanced significantly over recent years. Oil manufacturers have developed technologies that can extend engine oil lifespan. For motorcycles, manufacturers recommend changing the oil periodically, typically every 2000 km.

Synthetic oil technology brings significant improvements compared to the past. In addition to extending oil usage time, advanced oils provide optimal protection, reduce wear, and significantly improve fuel efficiency. Moreover, newer motorcycle models come equipped with oil change indicators like those found in cars, helping riders know when it's time for an oil change more accurately.

3. Engine oil can wear down the engine and cause fuel leaks

Synthetic oils can contribute to engine wear.

Synthetic oils, with their smaller molecular size, have been shown to wear down engines and cause fuel leaks. These small molecules can pass through cracks and tiny gaps that larger molecules from other oils cannot. Ultimately, synthetic oil can lead to larger issues from these small cracks and gaps.

However, in reality, if your vehicle's engine is in good condition and has no cracks, this is unlikely to happen. Regularly changing the oil and monitoring performance can help detect any changes
