How do I increase the fuel efficiency of my Vauxhall Zafira Life?

I've noticed that my Vauxhall Zafira Life doesn't have great fuel efficiency. Are there any tips or tricks on how to improve it? I don't want to spend too much time and money on it, but I want to make sure I'm being responsible with my fuel usage.

One simple way to increase fuel efficiency is to make sure your tires are properly inflated. Under-inflated tires can decrease efficiency by up to 3%. So, make sure to check your tire pressure regularly and inflate them to the recommended level.

Another tip is to avoid idling your car for long periods of time. This uses unnecessary fuel and contributes to pollution. If you're going to be parked for more than a minute, it's better to turn off your engine.

Plan your trips efficiently and combine errands whenever possible. This will reduce the amount of time you spend driving and ultimately save you money on fuel.
