They say Harry Firth, that great Australian race team manager would calibrate fuel gauges in the race cars he managed. I know he did this with the A9X race car. The reason is to allow pit stops to be planned accurately. Removes the uncertainly.
I don’t like uncertainly either, so I did a test on my 1990 Toyota Corolla.
I didn’t change my driving style, so the mileage I got was what I’d expect in normal city driving.
Results as follows:
Model |
AE92 1990 Toyota Corolla Automatic with 4A-F engine |
Fuel Tank Capacity | 50 litres |
Range until low fuel light | 307 kilometres |
Total range | 386 kilometres |
Low Fuel Light triggers when x litres left | 5 to 10 litres left. |
Don’t want to do this test yourself? You could try a site like Tank on empty for tests other people have done.
