we all think are 2.2's can be thirsty but after looking at reviews for other engined vauxhalls its not that bad, real drivers reviews are saying the 1.4s and 1.6s are doing 34-36 mpg combined some people even saying worse, 1 chap has a 150bhp cdti, doing 30mpg, and has takn it to vauxhall loads during warrenty and has even phoned luton, and they still say the cars fine, so my 2.2 doing 32-34 isnt bad
