How can I improve the gas mileage on my Vauxhall Vivaro?

I recently bought a Vauxhall Vivaro and I've noticed that the gas mileage isn't as good as I expected. Is there anything I can do to improve it?

One way you can improve your gas mileage is to make sure your tires are properly inflated. Under-inflated tires can cause your vehicle to use more fuel.

Another tip to improve gas mileage is to avoid unnecessary idling. If you're waiting for more than a minute, it's better to turn off your engine.

Regular maintenance, such as changing your air filter, can also help improve gas mileage. Make sure to follow the recommended maintenance schedule for your Vauxhall Vivaro.
