351C lubrication system lubricants
Jul 11 2010A fully grooved main bearing has the same effect on ultra-low viscosity oil as the tire tread grooves in a rain puddle it will channel oil away from the clearance between the crankshaft main journal and the bearing Therefore if you're going to use 0W/5W oil in a 351C use 3/4 groove main bearings instead of fully grooved main bearings
