Just to throw in some data here. I own a NASCAR Stock Car built by Bill Davis Racing that was campaigned by Ward Burton back in the early 2000's. It has a Pontiac 355 siamese block with a dry sump and external oil pump. It is a REQUIREMENT to heat the oil to 180 degrees (all 4 gallons of it) on start up, and even spin that external pump up to 20-30 psi oil pressure for a bit before the starter is engaged. Another racecar I have (2014 Radical) also has an oil heater on board for its Hayabusa four cylinder that has the same requirement before start up (heat to 180). Both cars are fitted with electric probes in the oil sumps. Yes they do it in F1, and any other close tolerance race series engine. Why? Well it does aid in flow, plus it gets the race engine to temperature and ready for RPM much quicker. I am not so sure it "activates" any molecules in the zinc or the like. But it is a real thing. Operating temperature (180) is ideal for a lot of things. They don't like being cold, or too hot. So getting it to 180 before even starting it would be beneficial.
