How can I improve the mileage of my Vauxhall Corsa?

I have been noticing that my Vauxhall Corsa's fuel efficiency has been decreasing over time. Is there any maintenance or driving techniques that can help me improve the mileage?

First, make sure to regularly service your car as recommended by the manufacturer. This includes changing the oil, air filters, and spark plugs. These simple maintenance tasks can greatly improve your car's mileage.

Another thing you can do is practice fuel-efficient driving habits, such as avoiding aggressive acceleration and braking. This can help reduce fuel consumption and improve your car's mileage.

Consider using a fuel additive to help clean your engine and improve its efficiency. This can also help reduce emissions and prolong the life of your engine.
