Viscosity of oil is more determined by ambient temps and internal tolerances at the bearings. Power levels have little to do with it. If you have the right oil in the right clearance, thickening it won't add protection, it will just make it harder for the oil to get there to protect.

Unless you went with really loose tolerances, 10w30.
