What is the best way to maintain the fuel efficiency of my Vauxhall Zafira Life?

I have noticed that my Vauxhall Zafira Life's fuel efficiency has been decreasing over time. Is there any specific maintenance routine I should follow to ensure that I am getting the most out of my fuel? How can I improve my overall fuel efficiency in the long run?

The best way to maintain the fuel efficiency of your Vauxhall Zafira Life is to regularly check and replace your air filter. A dirty air filter can reduce your fuel efficiency by up to 10%. Additionally, make sure to keep your tires properly inflated and to perform regular oil changes for optimal performance.

I recommend using a fuel additive to clean your engine and fuel system. This can help improve fuel efficiency and also reduce emissions. Also, try to avoid rapid acceleration and excessive idling, as these can also decrease efficiency.

In addition to regular maintenance, another tip is to avoid carrying unnecessary weight in your vehicle. The more weight your car has to carry, the more fuel it will consume. So try to keep your car clutter-free and only carry essential items.
