Water Temp issue

[J's boxster]

Your oil level gauge is fine. It's in the manual about the gauge timer It should be one bar low. That's fine. As far as temp, was it hot outside and did it lower at higher speeds? But temp in my box is usually at the 0 on the 180 mark, but box temp gauges are not known to be very exact. Just monitor temp and coolant level, but you should be okay.
