How to increase the fuel efficiency on a Vauxhall Combo Life?

I have been having trouble with the fuel efficiency on my Vauxhall Combo Life. Is there any way to improve it?

One way to increase the fuel efficiency is by regularly checking and changing your air filter. A dirty air filter can decrease fuel economy by up to 10%.

Another important factor is tire pressure. Make sure your tires are properly inflated to the recommended PSI. Under-inflated tires can decrease fuel efficiency and also wear out your tires more quickly.

Avoid aggressive driving, such as speeding and sudden braking, as it can significantly decrease fuel efficiency. Try to maintain a steady speed and use cruise control on long trips.
