a: multi viscosity oil ~
b: licorice stick or a DNA molecule
What:
"A chemical engineer I worked for explained it like this - the molecular structure is like a licorice stick or a DNA molecule - twisted. As the oil heats up, those additive molecules start to unwind & get longer - they'll twist back tighter & get shorter as the oil cools down. But if the oil gets too hot, the molecular structure just falls apart & you can't put it back together again. "
