It should read on the low side of the 8?
Odd, both my 986's run in between the 8 and 0 when fully warmed up and can venture to the high side of the 0 in outside temps above 90 degrees. I've been told by two shops, the dealership, and even a few folks on here that it was a 'normal' operating range.

Side note: awhile back, my daily driver started reading about what the image in the first post shows (even a little higher) and it turned out that there was tons of debris sandwiched between the condensers and radiators. A proper cleaning as described above (removing bumper cover and separating the condensers from the radiators) brought it right back down.
