I have a 13 multi and have done UOA's on Shell Rotella, the Shell Ultra, and Motul 300v with oil change intervals from 3,000-5,000. The Rotella shears down to a 30 grade in 3,000. The Motul 15-50 300v held up the best viscosity. There was not a lot of difference in wear metals between the 5 different oils I have tested. There was very little difference between the Rotella and the Shell Ultra in viscosity or wear metals.
