0W-30 viscosity oils available from the Mobil 1™ brand

0W-30 motor oils

A 0W-30 low viscosity oil can be used where a 5W-30 or 10W-30 is recommended. Switching to a Mobil™ 0W-30 advanced full synthetic formulation motor oil can help to increase engine efficiency and improve fuel economy versus higher viscosity oils.

0W-30 is widely suggested by American, European and Asian automakers as a viscosity alternate to higher viscosity oils for driving in frigid weather.

One of our 0W-30 oils carries the dexos®1 approval* specified for General Motors vehicles.

*The dexos® specification and trademark are exclusive to General Motors, LLC.

What do the numbers in 0W-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.
