I've a 2004 1.6 Zafira and am worried about fuel consupmtion ... at best I get roughly 300 miles to the tank. It doesn't seem to matter if I'm doing a long journey or the school runs I still get the same performance. This equates to 30mpg which would be in line with the urban figures but a long way short of the extra urban. Has anyone any experience of this car/engine? Should I be expecting a lot more from the engine? Regards Neil
