How can I increase my Vauxhall Crossland's fuel efficiency?

I just bought a new Vauxhall Crossland and I've noticed that I am spending a lot on fuel. What can I do to improve its fuel efficiency?

First, make sure you are regularly maintaining your car according to the manufacturer's recommendations. This includes regular oil changes, tire rotations, and air filter replacements. These simple maintenance tasks can greatly improve your car's fuel efficiency.

Additionally, try to avoid aggressive driving and excessive idling. These driving habits can use up a lot of fuel and decrease your car's efficiency. Instead, try to accelerate and brake smoothly and turn off your engine when you are stopped for more than a minute.

Another tip is to make sure your tires are properly inflated. Under-inflated tires can decrease fuel efficiency, so check your tire pressure regularly. And lastly, consider using a fuel additive or switching to a higher octane fuel to see if that improves your car's efficiency.
