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...
Engine oil viscosity has long been recognized as a key driver for fuel economy. This has led all major European passenger car OEMs to introduce engine oil specifications which cover the SAE 0W-20 viscosity grade, which reduce friction compared to higher viscosity grades (like SAE 5W-30, for ...
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 d...
Lubricant oil is then divided into 5 base oil groups according to saturate and sulfur percentage, viscosity index, temperature rating, and other things that confuse me. At the end of the refinement process each of these groups are referred to something calledbase stock. ...

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 ...
