How can I improve the performance of my Vauxhall Astra's engine?

I have noticed that my Vauxhall Astra's engine seems to be struggling and I am wondering what steps I can take to improve its performance. It feels like it is not running as smoothly as before and I am concerned about potential damage or problems in the future.

One thing you can do is regularly check and change your engine oil. Old and dirty oil can cause issues with engine performance.

Another possible solution is to clean your air filter. A clogged air filter can restrict the air flow to your engine, causing it to struggle.

You may also want to consider getting a tune-up for your engine. This can help optimize its performance and identify any potential issues.

Investing in high-quality fuel can also make a significant difference in your engine's performance. It may be more expensive, but it can help with fuel efficiency and overall performance.
