How to improve the gas mileage on my Vauxhall Insignia?

I love my Vauxhall Insignia but I've noticed that it's not as fuel efficient as I would like. How can I improve its gas mileage?

One thing you can do is regularly check your tire pressure. Under-inflated tires can decrease gas mileage.

Another tip is to remove any excess weight from your car, such as heavy bags or equipment, as this can decrease gas mileage.

Maintaining a steady speed and avoiding sudden stops and starts can also help improve gas mileage.

Consider getting a tune-up and regularly servicing your car to improve its overall efficiency.
