0W-40 motor oil
0W-40 oils are recommended by automakers for many types of European vehicles, including Mercedes-Benz, Porsche and Volkswagen. The viscosity is gaining popularity with American automakers for high performance engines in both cars and pickup trucks.
In this viscosity, we offer Mobil 1™ FS 0W-40 or Mobil 1™ ESP Formula 0W-40. They can be used in either gasoline- or diesel-powered engines.
If your diesel-powered engine requires an oil meeting the CK-4 specification, then choose Mobil Delvac 1™ ESP 0W-40. Note: We don’t compare diesel engine oils with motor oils formulated for gasoline-powered vehicles.
Mobil 1 ESP Formula 0W-40 carries the dexos®2 approval specified for General Motors vehicles.
*The dexos® specification and trademark are exclusive to General Motors, LLC.
What do the numbers in 0W-40 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.
