The consensus agrees that a driver should get an oil change every 3,000km to 7,000km or every three months. However, you can always refer to your owner’s manual which covers the recommended oil change interval for your specific make and model. Many of today’s newer vehicles will actually tell you when they are due for service. Remember: an oil change is essential because it acts as a lubricant for the internal cogs and gears under the hood. Without it, oil can turn into sludge and prohibit your vehicle from operating correctly.
