Bad idea. Mobil1 15w-50 would be a much wiser choice. Redline also makes a higher viscosity multi-weight. Both products have the higher ZDDP levels most of us desire.
Flow rate should also count for something. Getting cold 50W through a filter, tons of plumbing and an
oil cooler puts quite a strain on one's
oil pump gearing.
My $0.02.
