How Often Should Synthetic Engine Oil Be Changed?

[DerekLynn]

Semi-synthetic engine oil is typically changed every 7,500 kilometers, while full-synthetic engine oil is usually changed every 10,000 kilometers. Here are some important considerations for engine oil changes: Oil filter must be replaced simultaneously with engine oil: When changing the engine oil, the oil filter should also be replaced. If the filter isn't changed, residual contaminants on the filter will quickly pollute the new oil, causing it to degrade faster and fail to achieve proper filtration. Oil change intervals are closely related to actual usage: The oil change interval isn't fixed and depends on factors such as oil quality, driving conditions, and driving habits. If operating in harsh environments or with aggressive driving habits, it's recommended to shorten the oil change interval.
