I actually agree with your statement that one dollar a quart oil might do just as well. I just don't know of one. An indicator that I am going by for wear, is not the uoa, but valve adjustments. I used to check the clearances every 15k miles, but for years its been 30k miles. I can't remember the last time a valve was off more than a thou or two, and I'm picky. I did a double Auto-RX cycle and the filter, on the rinse cycle picked up hardly any crud. This engine is extremely clean inside and I don't know if I'd get that with dyno oil. I know is popular to take shots at Red Line, especially the price, but for me, it is doing the job just fine. Maybe we can answer your questions about long term performance in another 10 years. Right now, it's too soon.
