How can I increase the fuel efficiency of my Vauxhall Insignia?

I have noticed that my Vauxhall Insignia is not as fuel efficient as it used to be. What can I do to improve its fuel economy?

First, make sure to keep your vehicle well-maintained. This includes regular oil changes, tire rotations, and checking for any leaks. Keep your tire pressure at the recommended level to reduce resistance and improve fuel efficiency.

Avoid unnecessary idling by turning off your engine when you're stuck in traffic or waiting for someone. This can save you a significant amount of fuel over time.

Drive at a steady pace and avoid aggressive acceleration and braking. This not only saves fuel, but also reduces wear and tear on your vehicle.

Consider upgrading to more fuel-efficient tires and using the recommended grade of motor oil for your vehicle. This can make a noticeable difference in your fuel economy.
