Good Lord
Oil weight cannot be mathmatically averaged like you just did. The viscosity(flow rate at a specific temperature) and additives generally determine the weight. You simply cannot mix a 30 weight and a 10 weight and call it a 20 weight. You can start blending your own oil if follow your suggestion
