I have noticed that my Vauxhall Movano's fuel consumption has been higher than usual. What can I do to improve its fuel efficiency?

Regular maintenance is crucial for maintaining good fuel efficiency. Make sure to change your air filter and oil regularly.

Check your tire pressure regularly. Under-inflated tires can increase fuel consumption.

Avoid idling for long periods of time. It not only wastes fuel, but also increases emissions.

Consider investing in a fuel additive. They can help clean your engine and improve fuel efficiency.
