About this washer thing. I have been using new ones every oil change but I have to say I feel a bit stupid for doing so. This has nothing to do with the cost but only the PIA of having to get them from my dealer each time when the old ones look absolutely PERFECT! I use a torque wrench each time so I'm not squashing the aluminum washers so why the need for constant replacement? The manual calls them "crush washers" but they are certainly NOT crushed at all.
Please enlighten this old codger.
