if you can think of a better title let me know, want to start a sticky about amounts of engine wear after te1ardowns of using brands/types of oil at a given ratios. basically evaluating oil quality, I know it isn't practical to do a good side by side test with all the possible combinations, and variables (riding conditions, ect) starting possibly with these brands at these ratios to start with, awith picts of wear patterns, deposits, carbon build up, ect. PLEASE NOTE THAT THE USE OF SOME OF THESE OILS / RATIOS ARE AT YOUR OWN RISK THESE ARE NOT MY RECOMMENDATIONS USING SOME OF THESE OILS / RATIOS MAY RESULT IN ENGINE DAMAGE, ECT.
