How can I make my Vauxhall Crossland's engine more fuel efficient?

I've noticed that my Vauxhall Crossland's fuel efficiency has been decreasing. What steps can I take to improve it?

First, make sure your tires are properly inflated. Under-inflated tires can decrease fuel efficiency. Additionally, try to avoid idling your car for long periods of time and try to maintain a consistent speed while driving.

Another thing to consider is your driving habits. Avoid aggressive driving, such as quick acceleration and braking, as this can use up more fuel. Also, consider carpooling or using public transportation to reduce your overall fuel consumption.

Regular maintenance can also improve your car's fuel efficiency. Make sure to keep up with oil changes, air filter replacements, and tune-ups. This will keep your engine running smoothly and help improve its fuel efficiency.
