Question: How does the average fuel gauge work on this car?

The reason for my question is;
- Prior to my first oil change I would achieve 5L/100kms on the highway and 7.5l in the city.

- Now after my first oil change it seems to be tougher to obtain the above range although my driving habit has not changed?

- Also i notice the gauge is more responsive on a full tank and less as the level of fuel drops?
