I was curious if my bike would benefit in any way if the viscocity of the oil stayed a 40 weight during it's use. So I mixed one quart of Mobil 1 EP 15W-50 with 2.5 quarts of Rotella T Synthetic 5W-40 for this run. Yeah, it had a higher viscocity than if it was just a 40, but wear didn't seem to improve.
