Niles: I run Mobil 1 15W-50 in my 408 stroked Winsor. It is slightly on the heavy side viscosity wise, but the engine generates a lot of heat and I want the viscosity at the higher engine temps.
The accusump is a good addition, especially on the start up side. Pre-lubing any engine will significantly reduce start up wear and add to the engine life, regardless of the
oil in use(ND excepted). There are other products that will pre-lube, but won't provide
oil pressure if the
oil pump were to loose suction from the oil sloshing in the pan. However, the pump products can be interconnected to your ignition so that you can't start the engine without a preset oil pressure being reached by the pump.
