hi just a quick query might sound stupid but thought id ask so i checked my oil regularly and checked today on the digital gauge and its gone down one of the circles is this normal or would most people say i i have a leak somewhere ? my car is booked in next Monday for a full service so not worrying too much . only reason i am asking is because a previous garage when i had my vxr said some newer cars do tend to use a bit of oil ? would anyone agree ? thank you for any clarity on this
