How to maintain optimal fuel efficiency in Vauxhall Zafira Life?

I am having issues with my Vauxhall Zafira Life's fuel efficiency. There seems to be a decrease in its fuel efficiency and I am worried about the expenses this might bring. Can someone provide some tips on how to maintain optimal fuel efficiency in the Vauxhall Zafira Life?

One way to maintain optimal fuel efficiency in your Vauxhall Zafira Life is to make sure your tires are properly inflated. Under-inflated tires can increase fuel consumption.

Another important aspect for fuel efficiency is to keep your vehicle's weight in check. Make sure to remove any unnecessary items from your car as a lighter vehicle requires less fuel to operate.

Regular maintenance, such as oil changes and air filter replacements, also play a significant role in maintaining optimal fuel efficiency. Make sure to follow your car's recommended maintenance schedule.
