How to improve the efficiency of my Vauxhall Corsa engine?

I have noticed that my Vauxhall Corsa engine consumes more fuel than usual and is not running as smoothly as before. Are there any tips or tricks that can help improve its efficiency and performance?

Regularly changing the engine oil and air filter can greatly improve the efficiency of your Vauxhall Corsa engine.

Make sure to check and inflate your tires to the recommended pressure. Under-inflated tires can cause the engine to work harder and consume more fuel.

Avoid heavy acceleration and braking as it can put a strain on the engine and decrease its efficiency.

Keeping your car well-maintained and having regular tune-ups can help improve the overall performance of your Vauxhall Corsa engine.
