How to Choose the Right Engine Oil for Your Car

Engine oil is one of the most important fluids in your vehicle. It lubricates moving engine components, helps reduce friction and assists with controlling heat and deposits.

However, not every engine oil is suitable for every vehicle. Using the wrong oil can affect engine performance and, in some cases, contribute to premature wear.

Here are some important things to consider when choosing engine oil.

1. Check Your Owner's Manual

The first place to look is your vehicle's owner's manual.

Manufacturers specify the recommended oil viscosity and performance standards for each engine. Following these specifications is usually the safest way to choose the appropriate oil.

2. Understand Oil Grades

You may have seen labels such as 5W-30, 5W-40 or 10W-40 on engine oil bottles.

These numbers describe the oil's viscosity characteristics at different temperatures. The correct grade depends on the vehicle manufacturer's specifications and the conditions in which the vehicle operates.

Don't simply choose an oil because another car owner uses it.

3. Consider Your Vehicle's Age

Older vehicles may have different oil requirements from newer models.

A vehicle with a high-mileage engine may require an oil specifically formulated for higher-mileage vehicles, but the manufacturer's recommendations should still be considered.

4. Buy From a Reliable Source

Counterfeit automotive products are a concern in many markets, so motorists should be careful when purchasing engine oil.

Buy from reputable dealers, authorised distributors, established auto-parts stores or trusted service centres.

5. Don't Judge Oil Quality by Price Alone

The most expensive oil isn't automatically the best oil for your vehicle.

Instead of choosing based only on price, check whether the oil meets the specifications recommended for your engine.

6. Change Your Oil at the Recommended Interval

Even the correct engine oil eventually becomes contaminated and loses some of its effectiveness.

Follow the manufacturer's recommended oil-change interval. Your driving conditions may also affect how frequently servicing is required.

Frequent short trips, heavy traffic and demanding driving conditions can put additional stress on an engine.

7. Check Your Oil Level Regularly

Don't wait until your next service before checking the oil level.

Using the dipstick, you can monitor whether the oil level is within the recommended range. If the level keeps dropping, have the vehicle checked for leaks or other problems.

Common Mistakes to Avoid

Some motorists make simple mistakes when buying or changing engine oil.

Avoid:

  • Using an oil grade that isn't recommended for your vehicle.
  • Mixing different oils without checking compatibility.

  • Ignoring the manufacturer's specifications.

  • Buying suspiciously cheap oil from unreliable sources.

  • Continuing to drive when the oil warning light comes on.
  • Waiting too long between oil changes.


Conclusion

Choosing the right engine oil doesn't have to be complicated. Start with your owner's manual, use the recommended oil specification, purchase from a reliable source and maintain the correct service schedule.

The right oil and proper maintenance can help keep your engine running smoothly and protect it from unnecessary wear.
