A Ford Ka has a 40litre tank, Peugeot 106 45litres ... most of the cars I've driven have been between 40 and 60 litres.

But then I've mostly driven larger cars.

The car I have outside at the moment has something like a 90 litre petrol tank and a 100litre LPG tank :-) It's a LPG conversion Jaguar XJ6

I should have said "most petrol tanks (in cars hawkida is likely to drive) are 40-60 litres" probably.

Thanks.
