How do I increase efficiency in my Vauxhall Mokka's engine?

I've noticed that my Vauxhall Mokka's engine is not running as smoothly as it used to. What are some steps I can take to increase its efficiency and overall performance?

One simple way to increase engine efficiency is by regularly checking and changing your oil. This helps lubricate the moving parts and prevent excessive friction.

Another important factor is keeping up with regular maintenance and tune-ups. This can help catch any issues before they become bigger problems.

Also, make sure to properly inflate your tires and check for any leaks. Low tire pressure can negatively affect your engine's performance.

You might also consider using a fuel additive to improve the quality of your fuel and increase engine efficiency.

Finally, try to avoid unnecessary idling and aggressive driving, as these can also lower your engine's efficiency.
