Interesting thread, I have also been wondering about oil temps and what to run recently.
So I am currently running 15/50 in my newage wrx running around 330bhp, this is for weekend and track days, car wont get used much in the winter and is kept in a garage, should I run a thinner oil in the winter?
Also what is too hot for oil? I got up to around 120 (before I backed off) running 10/50 on track so fitted an oil cooler but havn't yet fully thrashed it on a comparable track day to do a comparison?

can of worms..............
but in simple terms for the weather conditions we have in the UK there is no reason to be swapping between winter & summer grades............
and for a fully forged motor used in arduous road use and expected to last for miles then a 10w60 will cause no detrimental effects
if we are talking race cars and extracting the last 'nth' of power then a very low viscosity 5w20, 0w20 race oil will be fine BUT not something i would recomend on the road and certainly isn't suitable for extended service intervals as it will be useable for 1 or 2 races MAX

Ah Dunx gave it away
Yes its a proper oil cooler, its the only model that has one fitted as standard due to the car being built for competition use (hence spec c means specification competition), also a transmission oil cooler so its built with temps in mind

I too backed off at 120 degrees, but on the "cooling down" lap it went up to 125 so I sourced a thermostatic cooler set-up.
