Actuly buster many F1 teams are the exception rather then the rule with regurds to Vis and raceing. Alot of F1 teams are useing 0W oil to gain HP. If the engine makes it through the race then the oil has done it's job. F1 engines have ho low end torque or HP all of their power is between 9000RPM and 17,000 RPM so the dynamic's invloved with this are a bit different then a daily driver that can be expected to see large amounts of loading at the crank when the oil pressure and volume are at their lowest point. F1 also runs a dry sump and galoons of oil. The oil is drained and the engine sent back to the supplier after each race. You also do not see engines that are not function efficently in raceing. The daily driver has bad fuel, egr system poisioning the oil and combustion gas's, marginal EGR and PCV system from lack of maintence, dirty worn out air filter, cheap copper plugs that have been in the engine for 80,000 miles and a pluged up fuel filter causeing irradic lean condition............ I used to see people all the time that had no idea that the oil had to be changed. They thought that you just kept topping it off. One car had 50,000 on it and was only 2 years old. The valves were carboned in the open postion and could not close due to carbon build up. THe other had 80,000 on it and still had the factory installed oil filter. So no I doubt that raceing is a true test an oil's properties these days. I think that a better test would be to heat soak the engine buy doing hard track work followed by a city circuit and repeat until the oil failed.
