Well the end result WOULD, be MY DECISION!!! As far as oil changes, thats done every 3000 miles and I use castrol GTX. I do quite a bit of hwy driving with the car and yea its paid( how could one sell something thats not theirs)....but thats besides the point. This is a discussion forum about the 7 series Volvo's. Because of that its often nice to get insight from other people about how well particular Volvo's hold up in the long run. Seeing that I don't currently have 200,000 plus on the car I was only wondering if there are any mishaps that this particular motor is prone to in its later age. The V-6 is a whole nother animal campared to the 4 cyl, and with all the years of experiance that brickboard has behind I assumed someone could advise on the road to take!!! Lets not forget though, IT IS MY DECISION!!
