How to improve fuel efficiency on my Vauxhall Corsa?

I've been noticing that my Vauxhall Corsa is not as fuel efficient as it used to be. What can I do to improve its fuel efficiency?

First, make sure your tires are properly inflated. Under-inflated tires can decrease fuel efficiency. Also, try to avoid sudden stops and starts while driving.

You can also switch to a higher quality fuel to see if that improves efficiency. And don't forget to regularly tune up your car, including changing the air filter and spark plugs.

Another tip is to avoid carrying excess weight in your car. This can decrease fuel efficiency. And try to drive at a consistent speed on the highway.
