How to increase fuel efficiency in my Vauxhall Combo Life?

I have been noticing a decrease in fuel efficiency in my Vauxhall Combo Life lately. What are some tips and tricks to help improve it?

One simple tip is to make sure your tires are properly inflated. Under-inflated tires can decrease fuel efficiency.

Another way to improve fuel efficiency is to avoid driving at high speeds, as this can cause a significant decrease in fuel efficiency.

Regular maintenance and oil changes can also greatly improve fuel efficiency.

Incorporating more eco-friendly driving habits, such as avoiding sudden accelerations and decelerations, can also help improve fuel efficiency.
