How to improve the fuel efficiency in my Vauxhall Vivaro?

I have noticed that my Vauxhall Vivaro is not as fuel efficient as it used to be. Are there any ways that I can improve its fuel efficiency?

One way to improve the fuel efficiency of your Vauxhall Vivaro is to regularly check and replace your air filter. A dirty air filter can decrease fuel efficiency by up to 10%. Also, make sure to keep your tires properly inflated, as under-inflated tires can also decrease fuel efficiency.

Another tip is to avoid idling for long periods of time. If you are going to be stopped for more than 30 seconds, it is more fuel efficient to turn off your engine and then restart it when you are ready to move again.

Lastly, consider your driving habits. Avoid aggressive driving and try to maintain a consistent speed. Rapid acceleration and braking can decrease fuel efficiency.
