Actually, the water can evaporate at lower temperatures than 100°C, just as it could with no oil. However, the oil layer can slow the evaporation dramatically. If the water is heated to boiling, with big bubbles of vapor popping up from inside the liquid, the oil will be less effective in slowing the evaporation.
Can you put oil in boiling water?
Do not put oil in the pot: As Lidia Bastianich has said, “Do not — I repeat, do not — add oil to your pasta cooking water! … Olive oil is said to prevent the pot from boiling over and prevent the pasta from sticking together. But, the general consensus is that it does more harm than good.

What temp does oil boil?
The exact temperatures will also depend on how pure the oil is. The boiling point estimates that I’ve found are pretty sketchy, but a fair estimate for soybean oil (most cheap cooking oil is soybean oil) is about 300 C (or 572 F).
