The engine does not have to get above the boiling point to expel condensation. It does need to run long enough to allow moisture and fuel residue to be expelled. That's usually half an hour at the least, and an hour or more under adverse conditions, such as cold wet weather. More is better. You may find that your engine operates at well above the thermostat's nominal temperature under most conditions. Oil typically runs hotter than the coolant in normal driving. When the engine is running, oil is pumped and sprayed throughout the engine interior, and sheets of oil flow over moving parts, the interior of the engine, and back down into the pan. This action, combined with heat and the draft through the crankcase, is very effective at expelling moisture from the oil.
