Optimal oil temperature anyone?

I have a 2008 c6 and a 2012 grand sport conv.
I live here in sunny myrtle beach south carolina.
Was thinking about a z06 oil cooler for each.
At ambient temp outside at 60f the oil temp is 216f.
Summer im not sure but know it is much higher.
Anyone know what is best ball park oil temp is for it to be best?
Was told oil can be to cool...Thanks for any input.

I like to see 190 - 200* for best oil pressure.

I agree that 212f is probably the optimal. Here's the best explanation that I've ever read. See post #6

My stock 08 m6 in SoCal runs 200f coolant, 230f oil, 40-45 pressure year round. There is a sleight variation in extreme temps.--105f at 90mph in Tx. raised both temps a little.

You want oil temp to exceed 100 deg c so that it can boil off any condensation / water that’s in the oil.

That is a wives tale. You want to be 200+ since bearing clearances are based off of that viscosity of oil.

180, I like to get it up to 200 and let it cool down to 180 and rip.

Supposed oil temps must be 220F to start burning off deposits and accumulated water vapor. Oils starts to break down at 275.

All oils are not created equal. Some are perfectly fine at 300+

oil is not only a lubricant, it is also a coolant, don't worry you probably cant get the oil too cold

it is impossible for oil to break down thermally.

A lot of people think that , but fact is oil will not really have much water in it to begin with and at 190-degree temp or greater water will EVAPORATE quickly from the oil . Ever watch water evaporate from a pot as it gets closer to boiling point . Boiling water is just a rapid state of evaporation . I personally like to see oil temps in the 180 range- 190 and no more than 200 on a street vehicle driven moderately . In race engines ( especially road race cars ) oil temps will get way higher .

Got a lot more then you, what temps do you think they use to refine oil? Heck of a lot higher then 275

You're comparing the crude oil refining process which develops multiple products with motor oil and you claim to be the expert? Okidoke.
