What you’ll need

  • Spanners
  • Metal ramps (optional)
  • Clean rags or paper towels
  • New engine oil
  • New oil filter
  • A drain pan or bucket

It’s important to keep on top of your vehicle maintenance and with our checklist, you’ll be able to do just that.

1. Get the right oil

Before you start, make sure you have the correct oil for your vehicle. Engine oil plays a vital role in keeping your engine protected and running efficiently.

If you’re unsure which oil your car requires, check your vehicle handbook or consult a qualified parts supplier before purchasing.

2. Warm the engine up

Just like warming up before exercise, it’s beneficial to warm your engine slightly before changing the oil.

Run the engine for around five minutes. Warm oil flows more easily, helping remove more contaminants and allowing the old oil to drain more effectively.

3. Drain the old oil

Once the engine is warm, switch it off and locate the sump plug underneath the engine.

Position your drain pan beneath the sump plug and carefully remove it. Be cautious as the oil may still be warm. Allow the oil to drain fully into the container.

Jamjar Top Tip: Remove the dipstick slightly and loosen the oil filler cap to improve airflow and help the oil drain more freely.

4. Replace the oil filter

Once the oil has completely drained, refit the sump plug securely.

Next, locate the oil filter and remove it. Fit the new filter according to the manufacturer’s instructions.

Many vehicles use a sealing washer on the sump plug, which may need replacing during each oil change. Always check your vehicle’s requirements beforehand.

Jamjar Top Tip: Apply a small amount of fresh oil to the new filter’s rubber seal before fitting it. This helps create a better seal and prevents damage during installation.

5. Refill with fresh oil

Check your owner’s manual for the correct oil capacity before refilling.

Using a funnel can make the process much easier and help avoid spills.

Add the recommended amount of oil gradually, checking the level regularly using the dipstick. Avoid overfilling.

Once filled:

  • Refit the oil filler cap.
  • Clean and reinsert the dipstick.
  • Check the oil level.
  • Start the engine and let it idle for a few minutes.
  • Switch off the engine and wait 5–10 minutes.
  • Recheck the oil level and top up if required.

6. Take it for a drive

Once everything is complete, take the car for a short drive.

Afterwards, recheck the oil level and inspect for any leaks around the sump plug and oil filter. If everything looks good, the job is done.

Regular oil checks between services can help identify leaks or engine issues before they become costly repairs.
