Multiweight oils (such as 5W 30) have polymers added to the oil. The polymers allow the oil to have different weights at different temperatures. Multiweight oils perform a great service of not being too thick at cold startup to provide engine wear protection by flowing more quickly to critical engine parts. The first number, the 5W of the 5W 30 viscosity, for example,
