Engine Operating Temperature

[PorscheFreak]

Morning chaps,

Just a quick one. I've done a few fairly long journeys in the car now and noticed that the temp rarely gets up to 80 or above.

Instead it tends to sit at around 70-75, and if cruising along a motor way at around 80mph it tends to sit just under 70.

Now only comparing this with the 911 that tends to sit anywhere between 80-90.

Temp just seemed low, surely better than being high, but thought I'd ask what optimum running temp should be.

Thanks
