I have been bracket racing for the last few weeks and need to dump to old oil that I had in the bike; Redline 10w40. For the change, I have either Rotella T3 or T6. The bike has been seeing less and less road time and more and more strip time. This being said, which should I go with? The T6 has the title of a synthetic, but the T3 should be more shear stable...opinions?? The engine on my bike is the same as a 650 Ninja/er6n.
