Dunno about the 10W-60.
But this is what Penrite says about their 15W60.
HPR 15 is a premium, full synthetic SAE 15W-60 engine oil. It features a DOUBLE LAYER of engine wear protection with FULL ZINC and Penrites advanced EXTRA TEN technology. It uses a combination of advanced additive technology and a low shear rate viscosity modifier, to ensure additional protection against wear, corrosion, oil oxidation, piston deposits and sludge under tough conditions.
