My car is 15 years old and is in pretty good order. It takes 40 litres and when the gauge says half, I fill up to 20 litres exactly.
A month ago when the tank was half full, I had to put in 27 litres (I fill up fortnightly). Yesterday, when it was half empty, I had to put in 24 litres. This time I alerted the station, who said it could be a problem with my car. I said that next time, I will check with another petrol station. I went to Toyota Fyshwick immediately who said the problem could be with either the car or the petrol station and suggested I ask the petrol station when their tanks were last calibrated. I do hope this is a minor problem with my car as this station is quite convenient for me.
Has anyone else experienced something similar?
