I have a 2009 XC70 with the T6. Now have 127,000 miles on it and it has been VERY reliable. It used a quart of oil between changes ONCE. Otherwise, no significant oil consumption. An inexperienced tech changed the oil when this happened, so there may have been a slight leak somewhere.Wondering if anyone with a 2011 S60 T6 AWD has surpassed the 100k mile mark and can report on reliability.
