a thin layer of metal across the whole magnet (must be the grinding into 2nd and 5th), the oil was flawlessly clear, no chunks of anything, really looked like it had just been put in. This oil has maybe 6000 miles on it, and has been in the car about 9 months. I will have to check with my mechanic (he loves Amsoil products), but the last oil I put in was redline mt90 (That was right before the engine rebuild). I will take pictures this time when I do the rear end. I did use the MaxGear 75w90.
