I've not yet calculated it, but a full tank used to get me through a month to work and back, now its empty in less than 3 weeks.

Finally had an engine check light come on, and had my mate connect his code reader on the obd2 port. It's reading as a fault on the o2 sensor on bank 1. Is it worth replacing this with one from a scrap yard or should I bite the bullet and just buy new?

New one for me, you go through the hassle of fitting a s/h one only for it to go down? Unless they're silly money then of course then if the replacement is cheap enough it would be worth taking a chance.
