Maintenance/Repairs. , oil, leaks, xc70. Anouchka April 11, 2011, 2:44pm #1. The old grey mare (2002 V-70 XC AWD with 195,000 miles) has been leaking oil. After multiple trips to 2 separate mechanics and no resolution whatsoever, I'm seriously considering a repair attempt using chewing gum and duct tape.
