Need some clarification, if an oil has to met a spec whether synthetic or conventional, and a synthetic flows better when cold, wouldn't the synthetic be classified as a different spec? Example a 10W30 conventional has to met the spec of being a 10W30, but the synthetic version of the same viscosity having better flow properties still be a 10W?
Does this question even make sense, or am I thinking it all wrong?
