Automotive and Four-cycle Off-road engine oil surpasses ASTM standard for Ultimate Biodegradability by more than 150%

STAMFORD, Conn.--(BUSINESS WIRE)--Green Earth Technologies [Pink Sheets:GETG] is pleased to announce that results of recent tests conducted by a nationally recognized, independent research and development firm show that Green Earths newest G-OILTM product, the 10W-30 in automotive and off-road 4 cycle engine oil, biodegraded over 90 percent in just nine days, easily surpassing standards for an Ultimate Biodegradable rating. The standard defined by the American Society of Testing Materials (ASTM) states that the oil under scrutiny must achieve degradation greater than or equal to 60 percent in 28 days. G-OIL achieved a landmark 150 percent of the required degradation in less than a third of the time.

ASTM Method D5864-05, (Test Method for Determining The Aerobic Aquatic Biodegradation of Lubricants), was used as the basis for the biodegradability analysis. Biodegradation is measured by collecting the carbon dioxide (CO2) produced when each sample is exposed to microorganisms. Comparing the measured amounts of CO2 production to the total amount of CO2 that could be produced from the amount of carbon present in the sample allows calculation of the percent biodegradability. Relative to the rape seed reference oil used, test results reported biodegradation of G-OIL to over 95 percent, essentially complete biodegradation when margin of error is factored in. This level of biodegradation was reached in only nine of the 28 days allowed.

These results confirm our belief that Green Earths motor oils are truly worth a place in the history books, says Jeff Marshall, President and CEO of Green Earth Technologies. Green Earth Technologies promised a biodegradable product and has more than delivered.

We are excited about getting the latest G-OIL into production and onto store shelves nationwide.

Unlike traditional, petrochemical-based engine oils from leading manufacturers, Green Earths G-OIL is made with American grown base oils called beef tallow, a by-product of the meat production industry. In addition to environmental benefits, G-OIL reduces dependence on foreign oil.

Mat Zuckerman, Ph.D., Chief Technical Officer of Green Earth commented, G-OIL is made from saturated fats, which are avoided in most foods, but are the perfect choice for consumer products that need stability on the shelf and high performance in engines. The biodegradability report for G-OIL provides consumers with confidence that they are getting the best of both worlds: delivering performance and a new higher standard for green.

G-OILTM 10W-30 Engine Oil is available now for off-road and recreational use in 4 cycle engines that require 10W-30 and SAE 30 and is scheduled to be available in the fall of 2008 for automotive applications in 10W-30, 5W-30 and 10W-40 grades.
