I just purchased a low milage 960 that looks in pretty good shape. Car runs well, and shows no signs of abouse. I am using Mobile 1 synthetic oil which comes recomended by many owners on the Brickboard over the Castrol Synthec Volvo dealers recomend. ( Why is Volvo so in love with Castrol as it is one of the cheaper oils on the market?) After 2000km I notice a slight cloudyness on bottom the dipstick which concerns me even though the car is burning no oil or using any coolent. I have seen other cars with this cloudyness on the dipstick and it usually meant either the car is running too cold or there is a coolent leak into the oil ( usually head gasket ) In my case neighter is true as the coolent has not varied an inch and the car is running too well to have a bad head gasket. Should I try an oil flushing solution with my next change or try a different brand of oil. Thermostat is new and so is the Volvo brand anti freeze.

Likely it is condensation at this time of year. Take it out on the freeway, run it for a good half hour to heat up the engine and vaporize all water, and check again.
I like the Bilstein engine flush system, btw, for cleaning out oil passages and de-varnishing the engine internals. Use a search engine to find a shop with one of these systems.
