I got two cars, three bikes, a boat, a lawn tractor, a lawn mower, a generator, a pressure washer etc. to maintain. I use Mobil 1 in all of them and change at long intervals/high miles. So far so good, none of them have worn out yet. I'm told the buffering capacity of motor oil outlasts the viscosity and shear resistance by a large margin and I believe it.

You'll never go wrong changing oil too much so do what makes ya happy.
