About to do an oil change on a 2008 XC90 6.2 AWD and have read conflicting torque values for the oil drain plug. I'm hoping someone can share the definitive Volvo torque value. Using OEM oil filter, o-ring, and crush washer.
I just toque to yield and a tiny bit more, which I suspect is pretty close to torque wrench specs. One washer will last four or five oil changes that way. Why can't they make an oil plug with an O-ring set in a groove so it could be used over and over again?
Some years ago I got my new VW back from the dealer after first oil change and they had really crushed the aluminum washer to the point of pieces disintegrating out from it. I suppose it was lucky that they hadn't stripped out the oil pan drain plug threads.
