Standard oil coolers - Thermostatic?

[SiH]

Does anyone know if the stock oil coolers (I have an R2 so twin coolers, but i guess it may also apply to the single cooler models) are thermostatically controlled at all? I ask as when cruising on the motorway, my oil temps are consistently in the low 60\'s - not good, far from optimum.
So I was wondering if the system had a thermostatic valve anywhere in it? As i suspect if it does, mine is malfunctioning.


Cheers all

each cooler has a stat where the oil goes in and bypasses it back if the oil is cold.  Where are you measuring the oil temp from?

That\'s great, cheers. The temp is being taken from by the filter housing I think - i\'ll double check when i get home.

I was seeing 80\'s on track yesterday (pretty constantly) which is fine, but my owrry is that one or more of the thermostats are playing up and not allowing the car to get up to temp a lot of the time.

60\'s is not uncommon.

Hmm, but is that not way below optimum temperature? surely i should be looking at around 80\'s/high 70\'s for optimum performance and protection?

you will probably find that it is at the important points.  

Thicker oil will run a little hotter, what oil are you using?

the temp you are reading is at the point where it will be lowest.
Once the oil goes back into the engine it will soon be higher.
That oil temp is fine where it is being read by the guage.
