How to improve the fuel economy on my Vauxhall Grandland?

I've noticed that my Vauxhall Grandland's fuel economy is not as good as it used to be. What could be causing this and what can I do to improve it?

Hi Sarah, have you been keeping up with regular maintenance? This could greatly impact the fuel economy of your car. Also, check your tire pressure and try to avoid unnecessary idling.

Hey Sarah, have you tried using a fuel injector cleaner? It can help improve the efficiency of your engine and ultimately improve your fuel economy. Also, avoid overloading your car as it can put extra strain on the engine.

Hi Sarah, make sure to use the correct grade of motor oil for your car. Using the wrong oil can cause the engine to work harder and use more fuel. Also, try to avoid aggressive driving and maintain a steady speed on the highway for better fuel economy.
