Oil Viscosity Explained

Why do I see a “W” on my engine and gear oil? Simply explained, this means the oil being used is a multi-viscosity application. The ‘W” in motor and gear oil stands for winter. The first number you see is the classification of the cold weather viscosity. The smaller the number is on this first number means the oil being used will be less viscous at lower temps. The second number after the “W” is the high temp viscosity, or how the oil is at operating temps. Once again, the higher the number, the thicker the oil would be. Thicker oil is not always better, depending on the age and wear of the engine, thicker viscosity oil can benefit you. On a brand new engine, this could actually hurt you. Ford and other manufactures have specifications normally listed on the oil cap or in the factory owner’s manual.
