Is there such a thing as too cool?
This is the one I have.

Mocal Sandwich Plate- 20mm thread
This compact, lightweight, high-flow sandwich plate incorporporates a 180o oil thermostat to regulate oil flow to the cooler until the engine is properly warmed up. The sandwich plate is 1-5/16" thick with 1/2" Parallel ports.
We strongly recommend the use of AN Male to BSP Male unions. These unions come by the pair and include the 1/2" Dowty seal. This is the proper fitting to use with any Mocal Sandwich plate.
Use of a NPT fitting is not recommended on Mocal plates. Damage to plate or leaks may occur.

Right. and you just disproved your own comment? The oil behaves as a 0w or 5w at cold temp and as a 30w or 40w at operating temp. So you still think the oil gets thinner as it gets warmer? did you read the links you posted?
You should have copy pasted this paragraph if you were going to try to prove anything:
An oil sold as 10w-40 is no thicker than 10 weight oil under Winter (10w) conditions, meaning below freezing. The 40 means it is no thinner than 40 weight oil at 212° Fahrenheit. So, the first number tells us the performance of the oil at or below the temperature of freezing water, and the second number tells us the performance at the temperature of boiling water. The chemicals added to the oil to accomplish this are called Viscosity Index Improvers (VIIs).
All this would have proved is that you're wrong.

Not all oils have a ##W## number.
Oils get thinner with a temperature inscrease.
Oils with special viscosity agents have the ##W## designations. All that means is a 5W30 runs like a 5W when cold and when hot, it runs like a hot 30W, not 30W when hot.
The reason why you buy oil with a low #W number vs the W## portion is because you want an oil that isnt as thin at higher temperatures and you also do not want to run a high weight oil when cold since that could hurt your motor since it would be so thick.
I guarantee you your motor oil thins out as you heat it up.
Run your oil up to 240 degrees f, check your pressure out. Pull your drain plug..........itll flow like water.

This is why I have the oiltemp gauge. I have very high pressure and need to know what the thinnest viscosity I can go is. Looks like it is running cool so I can use thin.
I am still waiting for summer.
I have 2 adapters one to accommodate the oil pressure and oil temp sensor and the other is the Mocal unit for the oil cooler
Plot thickens. I just changed the Castrol EDGE Ti 5-20 with Pennzoil Ultimate 5-20 and immediately temps are up to 140. Ambient is 72 water is at 200.
Can the Castrol be doing that much better at cooling?

Maybe because you NA and I'm boosted so my turbos heat up the oil for me
The worse thing about running too cool is fuel economy and emissions, I doubt it affects power, because when you beat on it it should be heated up properly. I dont think the numbers posted in your OP were cold enough to cause major mechanical problems.
