What's the best way to take care of the Vauxhall Insignia engine?

I noticed that my Vauxhall Insignia engine is not performing as well as it used to. What are some maintenance tips that I should follow?

First of all, make sure to change your oil regularly. This is crucial for keeping the engine running smoothly.

Another important aspect is to regularly check your coolant levels. Low coolant can cause engine overheating which can damage it.

Don't forget to replace your air filter when it gets dirty. A dirty air filter can affect engine performance and fuel efficiency.

Regularly check your spark plugs and replace them if needed. Faulty spark plugs can cause misfires and affect engine performance.

Lastly, make sure to follow the manufacturer's recommended service schedule. This will ensure that your engine is well-maintained and prevent any major issues.
