Common Mistakes to Avoid During an Oil Change

Jason's Car · 6 September 2026

Changing your car's oil is a crucial part of vehicle maintenance, yet many people make common mistakes that can lead to problems down the line. Understanding these pitfalls and how to avoid them can save you time, money, and extend the life of your vehicle.

What Are the Most Common Mistakes When Changing Oil?

One of the most frequent mistakes is neglecting to check the oil level before beginning the change. Many assume the oil is at an acceptable level without verifying it. Always check your oil level with the dipstick; this ensures you know how much oil needs to be replaced.

Another common error is failing to use the correct oil type. Each vehicle has specific oil requirements, whether it be synthetic, conventional, or a specific viscosity. Always consult your owner’s manual or a professional to ensure you’re using the right oil for your car.

Why Is It Important to Change the Oil Filter?

Skipping the oil filter change is another mistake that can be detrimental to your engine's health. The oil filter removes impurities from the oil, and if it’s not replaced, contaminants can circulate back into the engine. Always replace the filter when you change the oil to maintain optimal performance.

How Often Should You Change Your Oil?

Many vehicle owners are unsure about how frequently they should change their oil. While the traditional recommendation was every 5,000 kilometres, many modern vehicles can go up to 10,000 kilometres or more between changes, especially if using synthetic oil. It's essential to refer to your owner’s manual for the manufacturer's guidelines.

Are You Using the Right Tools for an Oil Change?

Using improper tools can lead to frustration and mistakes. Ensure you have the correct wrench size for your oil drain plug and a suitable oil filter wrench. Not having the right tools can make the process more complicated and lead to accidental damage to your vehicle.

What Are the Risks of Overfilling Oil?

Overfilling the oil can cause serious engine problems. It can lead to increased pressure, which may damage seals or cause leaks. If you accidentally overfill, it’s best to drain the excess oil to prevent potential damage.

Does Temperature Affect Oil Changes?

Yes, temperature can influence how oil behaves. In colder weather, oil can thicken, making it harder for it to circulate. Conversely, in hotter conditions, oil can thin out. Be mindful of the temperature when planning your oil change, and consider using oil suited for the climate you’re in.

How Can You Ensure Proper Disposal of Old Oil?

Improper disposal of old oil is not just a mistake; it's also harmful to the environment. Always take used oil to a recycling centre or a garage that offers oil disposal. Many local service centres, including Jason's Car, can help with this to ensure it is disposed of correctly.

What Should You Do If You Encounter Problems During an Oil Change?

If you run into difficulties, such as stripped bolts or leaks, don’t hesitate to seek professional assistance. Sometimes, what appears to be a minor issue can lead to significant problems if not handled correctly. It's always better to be safe than sorry.

How Can You Improve Your Oil Change Process?

To enhance your oil change experience, consider keeping a checklist of the steps involved. This can help you remember each part of the process and ensure nothing is overlooked. Regularly changing your oil and maintaining a log can also help track your car’s health over time.
