Its not uncommon for vauxhalls to use upto 1.2lt per 1000 mile. This is exactly what my Zafira uses and exactly what the book says is AVERAGE usage. Have a look through the vehicle handbook and find the oil usage figures and then work it out. Its will be something like 0.075m/100km which is 1.2lt/1000 mile. If its within the acceptable level then dont worry about it - just keep it topped up.

I nearly had heart failure when we first bought ours at the amount of oil it was using. Our old renault clio had 160k on the clock and never used a drop between oil changes. The zafira is different. Theres no leaks and no smoke but it was drinking it like a alki drinks alcohol. I asked the same question your asking now and I got the same answer ive just given you. You engine might be different figures but mine states this is normal and its continuted to burn through over 30lt of oil in the last 3 years/30k. Its shocking. I check our oil every week and usually top it up every 2 weeks+.

 

Hi. I bought a zafira 1.8 and noticed the same. It was using about 1 litre every 100 miles and only blowing smoke when revved hard from idle. Couldn't notice any smoke while driving at any speed. I have now replaced valve seals, piston rings and big end shells. I found that the oil guides behind the oil control rings were blocked solid and also the breather from cam cover to the throttle body was blocked so cleaned them out. Its running sweet so far but seeing as I only carried out the work yesterday only time will tell. But if the oil guide ports in the pistons were not cleaned out when the new rings were fitted then the oil control ring is still unable to guide the oil anywhere resulting in continued oil usage. Hope this helps. Sounds like poor workmanship to me.
