Car manufactures using a new engine oil for more fuel efficiency

Article by Christian A., on October 20, 2010

A new generation of engine oil from General Motors is expected to be used in all of its 2011 vehicles to get more miles per gallon from their vehicles.

The other automakers, including Ford Motor Co. and the Chrysler Group, have started to switch to new oil, which is known by its industry grading as GF-5 or SN, or GM’s Dexos1. GM warns though that using the wrong oil will result to engine damage that would invalidate the powertrain warranty.

The grade identifies oil that's made to help engines become more efficient and protects them further from wear. Various carmakers are doing this to get more horsepower out of smaller engines and have greater use of heat-producing turbochargers and superchargers.

The new oil has protection properties that also have the potential environmental benefit of raising the mileage interval between recommended oil changes.

On Oct 1, the Dexos1 and GF-5 oils arrived at the market. They replace the GF-4 standard from the International Lubricant Standardization and Approval Committee, which includes GM, Ford, Chrysler and the Japan Automobile Manufacturers Association as members.

The American Petroleum Institute uses the SN designation for the new oil. [via autonews - sub. required]
