Jeff, the old mentality of amount of oil changes is more important than the quality is a thing of the past. You brought up facts, science and proof, what qualifies you to give advice on oil and the effects of engine wear, do you build engines? I am very heavy into the race scene, from autocross to to world time attack and everything in between. I know for a fact what we run and why we run it.
I really do not feel like debating you because it's a waste of my time but I'll try to give an example that will make it more clear. Would you put just any oil in a BMW M5, Dodge Viper or any race motor for that matter? Of course not that would be crazy. But do you realize many cars today have as much or more hp/cylinder than race cars and very high performance cars. Just because we drive something daily does not mean it's just a car that can live off any oil. Look at all the turbo cars anymore, if anyone thinks a turbo charged car can live off of junk oil well then... It's no wonder why our industry is in such bad shape.
