My newly acquired CGTS takes an age for the oil temp to reach 80c.
Please can anyone advise what the maximum recommended revs are until the oil reaches correct temperature.
I’ve been keeping below 3k. Is this being over cautious?

In mine, a PDK, I switch to Sport during warm up as it keeps the revs a bit higher than standard and then drive 2-3 k revs until warmed up properly.

This is from the manual from a 987.2S



I wonder how many people leave their car to idle to warm up?

Oddly enough that is exactly what was done at my day at the PEC.

+1.

First 1min is sat still in the garage just to idle out.
Then use PDK auto to get out the street in normal mode.
Then over the PDK manual mode in Sports + or Sport and ensure revs are always kept below (4k myself).
Still takes a good 8-10min to hit 90c.
Persoanlly I would not stretch her legs until the car is at 90c

I use pretty much the same process to be honest, as I make sure both oil and coolant are up to 90c.

I only pretty much use the car in Sports+ mode all the time anyway unless i'm on a long run, its not great for fuel economy but I didnt buy the car for that.

We have just been on a weeks euro trip, mainly Germany, and a few laps of the Ring and the computer average was 32mpg for the 1600 miles. Great car

Has anyone else noticed that if you turn sport / sport plus off, the oil temp sits quite a lot higher? Mine is at 90 ish in sports plus and 110+ with all the fun stuff switched off...

110 isn't normal. I would get that checked out.

Remember that the oil will take longer to warm up than the coolant.

Ive seen mine working around that at times, most notiably on a long run but its normally around the 90's. Its also had a health check at my local OPC and everything is reported as fine.

Fair enough. In my experience, oil and coolant temp gauges vary in sensitivity from one car to another. My 997, for example, will show a notable drop in oil temperature if the car runs at low revs and high speed for a while after hard driving (effectively over-cooling for a minute or two, I suppose). By contrast, other 997s I have driven showed almost no needle movement, as did my 987.2. I prefer to know the gauge works, to be honest!

Why can't you warm the engine up just idling? I'm well aware you shouldn't but why not.

I know that is the received wisdom - but if it is the case why do they do exactly that at the PEC?

Coz it's a lot easier than driving the cars around sedately for 15 minutes!

Not the case when I was there - there was plenty of spare bits of track, link roads etc which would have speeded the process (at Silverstone). May be the case I suppose if it's a very busy day.

You don't think leaving a car to idle is a lot easier than driving it around for 15 minutes? If he leaves the car idling, the person who would otherwise be driving it around can do other work, scratch his bum, etc.

YOu are missing the point. I was in the car at the time with the instructor with both of us twiddling our thumbs. I would have much preferred to drive gently and familiarise myself with the car and both of us would have been less bored. If it was a case of switching the car on and leaving it, I would agree, but it wasn't.

Unlike most of our cars they are probably used all day long and never get cold. That probably offsets any damage warming them at idle. I think damage warming an engine at idle relates back to earlier times when cars had manual chokes and the bores were awash with fuel..
