I noticed that also vs M1 10w-30, and when it's 'up to temp' the temp is a tad higher than the M1. But if I flog it thru the twisties it doesn't seem to end up at as high a reading as the 10-30 M1. If I flogged the car with the M1 for say 30 minutes the gauge would be 1/2 way, with the Amsoil it doesn't get quite to the 1/2 point. Seemed strange to me.
I did some reading over at the oil guy's site. Jim from FLA posted a link awhile back and I read the whole thing front to back. I think I'm going back to 10w-30 full synthetic.
