Not been out for a run in a while so this morning was fine and dry, two minor problem.
First was the frost alarm going off all the time, is there a way to accept it and stop it, (2006 model).
Second was the oil temperature never got above 52C, so what is the opinion of you guys, poodle around all day or after a good distance start to use the car.

I have the same problem with the oil temp.just got to take it easy I guess you'd think thermostats could sort this problem.
the frost alarm drives me mad too!!!! Turn down the buzzer volume is all I can think of.

If you've been driving for 15-20 mins I would have thought all surfaces that need coating in oil would have been and wouldn't have a problem extending the revs to say 6k.
However after a little episode last weekend I would also take this as a warning NOT to push it this far. It may be dry but unless you've got cold weather tyres fitted these spiky engines can have you sideways in the blink of an eye on standard rubber, even on the straights.

I think the oil temperature concern is a design issue. It's the reason I'm thinking of installing a heater under the oil tank so I can pre-heat the oil before taking the car out and hence reducing the time required to get everything up to temperature. The only issue would then be that unless you're then really using the performance the oil temperature will drop down again. This whole issue is based on the assumption of what oil temperature is actually needed to ensure there is the least wear and damage potential to the engine. Does anyone know where exactly the recommendations on revs versus oil temperature came from? In cold weather you can only really use up to 4000rpm if you stick to the guidelines in 'mytuscan'.

I follow the guidance giving from John Ravenscroft:-

From Cold:
When starting, please be careful not to let it rev straight up so please make sure that you do not give it anything more than a tiny bit of throttle while cold cranking it over and then lift off as soon as it catches.

Then try to avoid more than 3000 rpm until the oil temperature has exceeded 40C, 4000 rpm until 60C and 7000 rpm until 80C. If it climbs above 110C, please keep the revs below 5000 rpm until the oil temperature returns to normal.
