I dont run an oil cooler either. Just remember that your coolant will warm up faster then your oil. Just because your coolant is up to temp doesnt mean that your oil is. Ill be switching to 0w40 this season. At a certain temp, there really isnt much difference in thickness of the different weights though. I dont have an oil temp gauge in my car, but thinner oil will cool easier. The only way to know for sure that your oil isnt getting too degraded is by having it tested. I havent tested any of mine in a while because i dont drive my car much anymore, so i usually just change my oil every few months or so which might only be 1000-2000 miles.
Yea but how does the thinner oil fair without a oil cooler on extended high way drives, or say a autocross were your up at rpm for a minute or a road race etc.
