Does not matter what the fuel capacity is.
DO NOT buy a 1.8 sx, they r terrible gutless thirsty engines, one of the worst engines in the range.
Whenever someone puts a petrol Xsara/C4 Picasso or a petrol C5/C8 in to our garage for servicing we always have a good chuckle about it, as the difference between the petrol engines & HDi engines really is enormous. The HDi engines r more economical, more powerful, more reliable (usually) & r no louder than the petrols, they r just so much nicer to live with.
