My daughter has a 2010 Mini non turbo with the 1.6l engine. We run synthetic oil in it. She bought the car 1 year ago had 88,000 miles on it and it has used oil from that time. She parks in the same spot on concrete daily and there is no dripping at all, no oil leaks that can be seen from underneath the car either. The car does not smoke when you crank it nor does it smoke going down the road because I followed her the other day to see. She will use 1 to 1 1\2 quart of oil in 1000 miles. Any thoughts?
