Green Earth Technologies have signed a two-year contract that will name their Ultimate Biodegradable "green" motor oil, G-OIL, the official motor oil of The American Le Mans Series and the International Motor Sports Association.

Under the agreement, G-OIL will be used in the Series' official safety trucks, which will also feature the G-OIL logo. The logo will also appear prominently at all Series races. Green Earth Technologies will utilize the American Le Mans Series and IMSA logos on their product packaging, promotions, publicity materials, advertising and on their web site.

This partnership is another significant step in the American Le Mans Series' efforts to be the global leader in green racing. In 2008 they created what has become the Michelin Green X Challenge, which awards teams that demonstrate the best overall performance, fuel efficiency and environmental impact during a race. It is also the only racing series in the world in which cars use one of four alternative fuels or energy sources that are virtually the same as the consumer can purchase at a service station.
