How can I maximize the fuel efficiency of my Vauxhall Vivaro?

I've noticed that my Vauxhall Vivaro is consuming more fuel than it used to. Is there any maintenance or driving techniques that can help me maximize its fuel efficiency?

Firstly, make sure that your Vauxhall Vivaro is properly maintained according to the manufacturer's recommendations. This includes regular oil changes and tire pressure checks. Additionally, avoid aggressive driving and excessive idling, as these can greatly impact fuel efficiency.

Consider investing in a tuning box for your Vauxhall Vivaro. This can help optimize your engine's performance and improve fuel efficiency.

When possible, try to plan your routes and consolidate trips to minimize unnecessary driving and keep your engine running at optimal temperature.
