Oil temp lags water temp by about 50 degrees. So when your oil gauge show 160, your water is already at 210 degrees F.
Coolant only cools the block and head of heat that has traveled THROUGH them. Oil cools the moving parts, pistons, crank, valvetrain, turbos .... where the heat is generated through combustion and friction. Oil temp is a much better indicator of engine condition them water temp. The owner's manual gives a pretty good explaination of this.
No matter how fast I go, there's always
someone slower in front of me.
You can lead a horse to water, but you can't make him jet ski.
