One advantage that a 5W will have over a 0W within the same grade is that it is a more stable oil since it will contain less viscosity modifers (and more stable oil pressure as the oil is used). If you compare Red Line, their 0W oils contain some viscosity modifiers while their 5W oils contain none. |
I wouldn't say that's true for EVERY line of oils...
