What's the best way to improve fuel efficiency in a Vauxhall Grandland?

I recently purchased a Vauxhall Grandland and have noticed that it's not as fuel efficient as advertised. What can I do to improve its fuel efficiency?

Regular maintenance is key to improving fuel efficiency in any vehicle. Make sure to change your air filter, oil, and spark plugs according to the manufacturer's recommendations.

I recommend keeping your tires properly inflated. Under-inflated tires can decrease fuel efficiency by up to 25%.

Avoid aggressive driving and excessive idling, as these can also decrease fuel efficiency. Try to maintain a steady speed and use cruise control when possible.

Consider investing in a fuel additive to improve engine performance and fuel economy.

When possible, try using the eco mode in your Vauxhall Grandland. This can help improve fuel efficiency by adjusting engine and transmission settings.
