winter or “W” viscosity rating — the “5W” in 5W-30 motor oil. The lower the “W” rating, the faster the oil flows when cold and the easier it is for the engine to turn over when starting.
Another problem with this higher viscosity oil is its low-temperature pumpability. During cold starts, the oil may be very thick and difficult for the oil pump to deliver to vital engine components like the lifter valley. This lack of oil at startup will lead to premature wear, as the com...
The challenge for engine oil is to maintain the correct flow characteristics to protect the engine when it starts cold and then during running. Viscosity improvers help to ensure the engine oil is not too thick in cold weather, as too thick an oil may not circulate properly on starting ...

Since the temperature has a substantial effect on the oil viscosity, there is a need for oil of different grades for usage in different weather. For instance, it could be perfect to use oil with 40 W for a long road trip in summer when the engine is already hot. But it will be a ...

When a harmonic force acts on particles inside the solid media, there is a transition process of the particle's motion from a static state to a steady harmonic vibrational state induced by the inertia of the particle and the viscosity of the medium. Naturally, the particles in a solid ...
