The weather effects engine oil. In hot weather, expect the oil to become thinner. In cold weather, motor oil will thicken. Thanks to additives put into the motor oil, there’s a counterbalance to the thinning and thickening effect. The oil’s viscosity level tells buyers about its “temperature value.”

Low-viscosity motor oil is thin, and it’s appropriate for cold weather. The thin motor oil will slightly thin and perform better. High-viscosity motor oil is thicker, so it thins out in hot weather, but not to the extreme. If the oil is too thin, it might not lubricate effectively. Oil that’s too thick also creates problems. So, the cold-adjusting additives are helpful during winter in Belle Fourche, SD.

You can figure out the viscosity rating by reviewing the alphanumeric delineation on the container. The number before the letter W refers to the low-temperature rating. The one after the W refers to the high.
