As you cruise Salem, OR streets, motor oil viscosity ratings are probably not on your mind at all. Our service team wants you to be an informed consumer. The following information will help you make sense of motor oil viscosity ratings.

Viscosity refers to how slowly or quickly motor oil can move through your engine. Oil with a higher viscosity will be thicker and move more slowly. A hot engine needs oil with a higher viscosity to run smoothly. A cold engine needs a lower viscosity motor oil before it becomes warm.

Motor oil viscosity ratings typically have two numbers separated by the letter “W,” such as 10W30. The first number refers to the viscosity when the engine is cold and the second when it is hot. Our Volkswagen of Salem service team can answer your questions and help you get the right oil for your vehicle.
