Hi there, first I'd just like to thank everyone here who have taught me a lot about the x5. i found this community not long ago and i must say i'm starting to like it very much.

anyways, i just completed the oil change, i followed every detail in the guide on this site. the author said he took 7.5 litres of oil. well i had to use up all the 8 litres i bought and it's still not full (not low either) according to the dipstick. i checked and i dont believe there's a leak. what gives? thanks

ps - oh yeah i bought 8 bottles of castrol synthec 0w30, 1L each.
