Quick question. My 2012 Volvo XC70 has been dealer services since birth, with oil changes performed using partial synthetic oil. I am considering moving to using full synthetic oil. The car has 130K miles on it. Many years ago I changed to using full synthetic on 2 of my Volvo 740 turbo wagons at mileages in this range. There were many warnings against running the risk of seal leaks in doing so where the car had previously only used conventional oil. It sounded like a wives tale to me and I went ahead to using full synthetic. Very soon after, as I had been warned, both cards developed severe front and rear engine seal leaks. So I am checking in about whether this would be an issue in the case where partial synthetic motor oil had been used up to 130K miles in a newer Volvo XC70.

Looking to hear whether this is a risky idea or from folks who have made this switch and their experience in this regard,

Thank you.
