What is the most efficient way to improve the fuel efficiency of a Vauxhall Movano?

I have recently purchased a Vauxhall Movano and I am looking for ways to improve its fuel efficiency. Is there any specific maintenance routine or driving technique that can help me achieve better fuel economy? Thank you.

Regular maintenance and tuning of the engine is essential to achieve optimal fuel efficiency. Make sure to follow the recommended maintenance schedule and use high-quality fuel and oils.

Driving at a constant speed and avoiding sudden accelerations and decelerations can significantly improve fuel economy. Also, try to avoid heavy loads and reduce air resistance by keeping your tires properly inflated.

Consider using a fuel additive to improve the combustion process and clean your engine. Just make sure to choose a product that is compatible with your Vauxhall Movano's engine.
