How to optimize fuel consumption on Vauxhall Vivaro?

I recently purchased a Vauxhall Vivaro and I am concerned about fuel consumption. How can I optimize the fuel efficiency of my vehicle?

Make sure to properly maintain your Vauxhall Vivaro by regularly changing the oil and air filters. This will improve the engine's performance and ultimately lead to better fuel efficiency.

Avoid heavy acceleration and braking, as these actions can significantly increase fuel consumption. It's best to drive smoothly and maintain a constant speed.

Regularly check your tire pressure and make sure they are properly inflated. Under-inflated tires can decrease fuel efficiency and also wear out quicker.

Consider using a fuel additive or switching to a higher grade fuel, as these can help improve fuel efficiency. However, be sure to consult your vehicle's manual and manufacturer before making any changes.
