No, multi-viscosity oil does not get thicker when it's hot; rather, it becomes thinner. Multi-viscosity oils are designed to maintain their effectiveness over a range of temperatures. For example, a 10W-30 oil has a lower viscosity when cold (10W) and a higher viscosity when warm (30), allowing it to perform well in both cold and hot conditions. Thus, while the oil's viscosity changes with temperature, it is formulated to ensure optimal lubrication in various environments.
