The thing about trying all of these different oils is, how are you going to know which one is better / worse, unless you run that oil, and ONLY that oil, for the entire life of that particular engine? Then completely disassemble it and gauge everything, and compare it to another engine you've run a different oil in for the life of it. With all other things equal. That could take years, and wind up costing tens of thousands of dollars. Let's face it. There is no way anyone can tell what oil is in the car by sitting in the drivers seat. My truck is a 1991, and is 26 years old. In that time I've probably run over 15 different brands and weight of oil in it. Some regular, some synthetic. With maybe a half dozen different brands of oil filters.
The truck runs like a top. It still has plenty of power. It doesn't use any oil, and passes emissions every year by a large, comfortable margin. So after 26 years of driving, there is no way I could begin to tell anyone, "what is the best oil they should use". There are probably over 100 different kinds that will all work equally as well.
Yeah, I get that this is a track car, and will be raced. Buy why wouldn't the same thing apply, and apply even more so? Being as everything is being pushed to the limit.
