First... everyone is pretty much spot on. Running the engine will heat the oil (and any water in it). The water doesn’t have to hit the boiling point to be eliminated. Like a cup of coffee, or a puddle in your driveway, the water will evaporate/vaporize. The car just needs to be driven 15+ min's.... not a start up, bring to operating temp and shut off.
I do have a question though… where do you pick up the oil temp? Is it pre or post oil cooler? In any case, with a high HP engine in a light car the engine doesn’t work that hard to get that hot, but I’d think the “pre” oil cooler temp would be at least ~180 degs. Mark
