This thread might start and response storm. LOL
I plan on doing interim oil changes on my new 2014 XC90 between the scheduled 10,000 mile intervals. Doing some research, I ran across a couple of statement or theories on copper vs aluminum crush washers. And some statements.
Copper:
+ Has heat properties more similar to steel for steel oil pans.
- Copper is denser than aluminum meaning there is a risk of stripping threads in an aluminum oil pan, because copper needs more torque to start the crush.
Aluminum:
+ Crushes easier than copper and seals better being less dense.-
- May react more strongly with other chemicals and materials than copper.
I'm curious as to what you all think is the better crush washer for the oil drain plug.
I haven't done my first oil change yet, so I don't know if the oil pan on the 2014 3.2L 6 cylinder engine is aluminum or steel. You might comment on that. I can figure it out real easy when I get around to doing my oil change when I drop the splash shroud off.
Thanks in advance for any input on this subject.
