How to improve fuel economy on a Vauxhall Vivaro?

I recently bought a Vauxhall Vivaro for my small business and I've noticed that my fuel costs have increased. Is there any way to improve the fuel economy of this van?

Regular maintenance and vehicle checks, such as tire pressure, oil level, and air filter replacement, can greatly improve the fuel economy of your Vauxhall Vivaro.

Try using a fuel additive or upgrading to a higher quality fuel. This can reduce engine deposits and improve fuel efficiency.

Consider using a GPS or route planning app to avoid traffic congestion and take the most efficient route for your trips.
