Hello,

Three weeks ago I bought my new Mazda 6 Sport 2.0 CD Top. Until now I drove about 3000 km. This model has a bord computer and always shows how many kilometers I can drive with the tanked petrol.
Now my question is, how many petrol is remaining in the tank when the tank lamp starts glowing.

I hope that anybody can help me concerning this.

 

It will vary from car to car due to production variation. The best way to measure it is to fill up right after the light turns on, but only fill up until the pump shuts off automatically the first time. Do this for a couple of tanks and it will give you a fairly good idea of how much gas you burn from full until the light comes on. Subtract that total from the total capacity of the gas tank in your car (capacity should be listed in the owner's manual) to figure out how much is left in the tank....
