Concerning high mileage. This is probably cheating though. My 1986 Volvo has 218000 miles and the oil was a beautiful honey color after 7000 miles. Just switched to Mobil 1 as I had to have the front seals replaced. Warning though the PVC was plugged which caused that failure.

My Dad owned a few Volvos when I was very young, I remember only a bit about them, but my Dad still mentions the stories from time to time. Dad has always done his own mechanical work on cars, and now so do I.

Dad's first Volvo story goes like this: Once upon a winter, the PCV valve accumulated some water condensation which inevitably turned to ice and froze up the PCV valve. So then with the PCV plugged and no means of crankcase ventilation, the oil blew out the engine seals until the sump was nearly dry. Made one helluva mess, I don't know if Dad had to replace the engine seals or not. After Dad topped up the oil, he ripped out the PCV valve so it couldn't freeze shut anymore, and cut the PCV hose to vent into the atmosphere, no more problems after that.

The other story Dad mentions of the Volvo was that it never seemed to shift quite right since it was new. My Dad had the tranny out and noticed that one of the syncros were installed backwards, from the factory! Of course he fixed it right.

Another PCV story happened to the brother of my brother's fiancee, who neglected to change the PCV valve in his Ford Merkur. Similar story except he lost his oil at a traffic light and had his car towed to the dealer. After a bad experience with the dealer, the car never seemed to run properly so he sold the car.

Moral of the story: replace your PCV valve, there is a good reason it is deemed a regular maintenance item! It's a good thing that neither of my cars require a PCV valve, the PCV line vents straight into the intake.
