Agree to a point. My takeaway from these various oil related articles I've read is that most (pretty well all?) of the name brand oils are pretty decent quality nowadays... and certainly much better than 20+ years ago. This business tho of mineral based oils (automotive or motorcycle) showing significant degradation in as little as 800 miles really surprised me. These scientific studies do seem to confirm that full synthetics degrade much slower, holding up much better under severe use. I would rather know than not know (about the truth in motor oil quality/performance), particularly given the claims of some manufacturers, and the huge price difference between some oils. Check out the price of a new KLR head - sure makes me very reluctant to attempt to save a few pennies extending an oil change interval! I don't think that anyone here is really suggesting deviating away from OEM viscosity recommendations or oil change intervals.
