How often should the spark plugs be changed in a Vauxhall Corsa?

I recently bought a used Vauxhall Corsa and I am wondering how often I should change the spark plugs for optimal performance and fuel efficiency. Any advice?

It is recommended to change the spark plugs every 30,000 miles or every 3 years, whichever comes first. This will ensure proper combustion and maintain the performance of your Vauxhall Corsa.

If you notice a decrease in fuel efficiency or your engine is running rough, it's a good idea to check and potentially replace the spark plugs. It's better to err on the side of caution and change them every 2 years or 25,000 miles.

In general, it's important to follow the recommended maintenance schedule for your specific Vauxhall Corsa model. Check your owner's manual for the exact mileage and time intervals for changing the spark plugs.
