It could be due to a clogged air filter or a problem with the fuel injectors. I suggest getting these components checked and replaced if necessary.

Another possible cause could be a faulty oxygen sensor. This can lead to incorrect readings and impact fuel efficiency. Consider getting a diagnostic test to check for any error codes related to the oxygen sensor.

You may also want to check your tire pressure. Under-inflated tires can cause your car to use more fuel. Make sure to regularly check and maintain the correct tire pressure.
