Yep once water begins to boil, it changes state to steam & can not get any hotter in liquid form. Pressure in the pan is not enough to raise the boiling temp more than just a few degrees so as Rusty states 110 Deg F is more than adequate to boil off the water. Also most modern oils / Synthetics are designed to flow/protect at very low temps

You're close. You should work in a power plant. Have water temps as high as 1,500F, steam temps of 2,000F. To get water temps that high. You have to have it under pressure. Pressures high as 3,000 psi. To get temps that high. Most use a 3 element boilers. For our discussion. Water starts to evaporate at around 100F. By 212F, it's boiling. And the little moisture that is trapped in the oil will be gone at around 150F to 170F. Unless you have popped a head gasket.

Yep the pressure makes all the difference, the same as you can boil water at 0 Deg in a vacuum

Yeah, I used to do that trick when teaching noobs on making steam for power generation. Teaching steam tables was a headache. And to get across the difference between wet steam and dry steam.
