How to increase fuel efficiency of Vauxhall Vivaro?

I just bought a used Vauxhall Vivaro and noticed that it's using a lot of fuel. Is there any way to increase its fuel efficiency and save some money in the long run?

One way to increase fuel efficiency is to make sure your tires are properly inflated. Under-inflated tires can decrease your MPG by 0.2% for every 1 psi drop in pressure. Regularly check your tire pressure and inflate them to the recommended level.

Another tip is to avoid unnecessary acceleration and braking. This is especially important for stop-and-go city driving. Anticipating traffic and using cruise control can help reduce fuel consumption.

You can also consider using a fuel additive to clean your engine and improve its efficiency. Just make sure to choose a reputable brand and follow the instructions carefully.

Performing regular maintenance on your Vauxhall Vivaro can also help improve fuel efficiency. Make sure to change the engine oil, air filter, and spark plugs according to the manufacturer's recommendations.

Lastly, try to reduce the weight of your vehicle by removing any unnecessary items from the trunk or cargo area. The lighter your Vauxhall Vivaro is, the less fuel it will use.
