How do I maintain my Vauxhall Vivaro's fuel efficiency?

I have noticed a decrease in my Vauxhall Vivaro's fuel efficiency lately. What can I do to maintain its fuel efficiency and save on fuel costs in the long run?

Maria, it is important to regularly check and replace your vehicle's air filter. A dirty air filter can significantly decrease fuel efficiency. Additionally, make sure to keep your tires properly inflated, as under-inflated tires can also lead to poor fuel efficiency.

Hey Maria, try to avoid unnecessary idling and aggressive driving. Both of these can greatly impact your Vauxhall Vivaro's fuel efficiency. In addition, keep up with regular maintenance and oil changes to ensure your vehicle is running at its best.

Maria, have you considered using a fuel additive? These can help improve fuel efficiency and clean out any buildup or deposits in your engine. Just make sure to choose one specifically designed for diesel engines.
