Gast Tank Size - In Litres

[capster59]

So I just get my new car and it is great...S with lots of stuff. I was told it was a 50 litre tank, when I read the manual it says 50 litre including a reserve of 8 litres... I went my first full tank and got 675 km(419 miles) andthen filled up with 52 litres of gas.
So I dont know if I was right empty and filled the neck up with 2 litres of gas or the tank actually holds 58 litres....

Anybody know for sure? I can convert from gallons if need be.Thanks
