Multiviscosity Oil Molecule

a: Multi viscosity oil ~
b: a coil

What: "The oil molecule in the multiviscosity oil is like a coil. When it is cold the coil shrinks and is short, and when the oil is hot the coil stretches out and is long. When the coils are long they tangle up with each other, that is what makes the film strength, they don't want to separate and so stays between the metal parts. When cold and short, they don't tangle up with each other as much, hence they are more "willing" to move along and flow, but they also don't have as much film strength." This is a very good and succinct explanation.
