Motor oil that flows smoothly through the engine helps a car in many ways. You don’t want thick oil that creates sludge, and thin oil isn’t reliable when it comes to protecting parts. So, drivers must look at the viscosity rating on motor oil when making a purchase. The rating helps them choose the right oil for the right season.

Cold weather thickens oil, and hot weather makes it thinner. Motor oil has additives to keep the oil from becoming too thick or too thin when the weather changes. Reading the viscosity rating tells you what oil to buy in particular temperatures.

On the packaging, you will see numbers followed by the letter W, followed by a dash, and ending with another number. The first numbers plus the W reflect the cold-weather viscosity rating. The second number represents the hot weather rating.
