How to improve the fuel efficiency of a Vauxhall Vivaro?

I recently purchased a Vauxhall Vivaro and I'm looking for ways to improve its fuel efficiency. Any tips or advice?

One way to improve fuel efficiency is by regularly checking and replacing air filters. This helps the engine run more efficiently, reducing fuel consumption. Also, make sure to maintain proper tire pressure and avoid excessive idling.

Consider switching to a high-quality synthetic oil, which can improve fuel economy. Also, try to drive at a consistent speed and avoid sudden acceleration or braking. This can greatly impact fuel consumption.

Another tip is to unload any unnecessary weight from your Vauxhall Vivaro. The heavier the vehicle, the more fuel it needs to move. So, declutter and remove any heavy items from the back of your van.
