Any oil that gets into the combustion chamber(CC) will burn along with the fuel no what the viscosity. Higher viscosity lubricating oil will resist getting into the CC better than a lower viscosity oil. But even if any lubricating oil that got into the CC didn't burn, it would just go out the tail pipe and the same amount would be consumed.
