what kind of oil do I put in a 1997 960 station wagon volvo??
I would stick with what Volvo recommends in the owners manual. Oil weight and type is a debatable topic, as others have switched to Full Synthetic. All up to you. I've read enthusiast of 960's run Mobil 1 5w-30 or 10W-30 depending on climate.
Look at your manual. There should be a chart in the Service or Maintenance section.
