Change the oil in your ride regularly. You know that, but how much do you know about the oil you put into your steel steed?
IT'S NOT WEIGHT
Motor oil is commonly sold with a "w" and some numbers. A lot of people say the "w" stands for weight. It means "winter." The Society of Automotive Engineers (SAE) came up with the numbers and the "w" for motor oil. "The numbers 0, 5, 10, 15, (20) and 25 are (sometimes) suffixed with the letter W, designating they are "winter" (not "weight") or cold-start viscosity, at lower temperature," says the Lard Oil company.
