yes shanneba confirmed that the needle is calibrated to read dead center with something like a range of 85-115 range. (something like that)
OP, if your gauge is cocked to one side during normal driving (basically all day) then the needle was possible messed with (repositioned) at some point. It should read dead center under normal operating temps (assuming your cooling system is healthy and bled correctly)
No more pimpin' and posin'. Time to do full professional maintenance.
