31 litres petrol in M-800-possible?

AkMar · 7th May 2007, 00:18

Hello,

I have a question for the experts, although nominal, but it has been in my mind for quite some time.

A couple of times, the person at the petrol pump managed to fill 31 litres of petrol into our car. The owners manual as well as the website says that the capacity is 28 litres. At the time of
refuelling, the fuel indicator had just touched E on the guage.

Is this possible or we were fooled by the pump guys?

It's possible if you fill the petrol till the brim. But it's a not a good idea because petrol evaporates and you also have to lug around the excess weight of the fuel.

Go for more than 28 litres if you are going on long drive else fill upto brim is not a good idea.

edit : brim = 1-2 litres less then brim but more than auto cut.

whatever be the distance filling up to the brim is not recommended cos it goes against the principle on which the system was designed.

trust me mileage also will be better (marginally) if you stick to proper filling exercise, though am not sure if its coz of proper calculation or some other reason whereby the fuel might be wasted/un usable.

cheers

Filling to the brim is not a good idea at all. Petrol heats up quickly, and it need space to expand. Auto cut is designed to allow this space to petrol. You can go a little bit above auto-cut (to pay in round figure), but leave some space for petrol to expand, other wise it may create a very high pressure zone inside.

Petrol pump guys cheating you, sounds a more likely reason than anything else. Are you sure you checked for the '0' before they started filling? They sometimes also turn and twist the pipe to trap some petrol in it. Although, that would have made the difference of 750ml-1L at max; not 3 litres.
