The 10W-30 viscosity has all but disappeared as a primary recommendation for vehicles except for certain diesel engines, and today serves as a viscosity alternate choice.

Many manufacturers have transitioned to 5W-30 motor oil viscosity, and 5W-30 or 0W-30 oil can be used in applications requiring a 10W-30 grade motor oil.

We offer a variety of Mobil™ 10W-30 viscosity motor oils, including products designed for high mileage vehicles, and for those of you looking for an extended drain motor oil.

What do the numbers in 10W-30 mean? The numbers refer to the weight and thickness, or viscosity, of the oil. Motor oil gets thicker when it’s cold and thinner when it heats up. The first number indicates the viscosity of the oil at a cold temperature, and the second number indicates the viscosity at operating temperatures.
