In cold climates, motor oil can become too thick to flow properly, which is why oils are rated with a "W" number like 5W-30. The "W" stands for winter, and the number indicates the coldest temperature at which the oil will still pour. Using the wrong oil in freezing weather can prevent your engine from starting because the oil becomes almost solid. This is why mechanics recommend switching to lower W-rated oils before winter arrives.
