Green Earth Technologies’ products, including G-OIL, are made from American grown base oils, achieving an Ultimate Biodegradability ranking form the ASTM standard D5864 which defines 'Ultimate Biodegradable' as a product that is rapidly absorbed (eaten) by microorganisms by 60% in 28 days. G-Oil proudly exceeds those standards.
The biodegradability of motor oil depends on the feedstock. If the feedstock is crude oil, then the biodegradability that can be obtained is between 15% -35% and synthetics biodegradability value is between 5% - 30%. For G-OIL, where the feedstock is plant oil or animal fat, the biodegradability is significantly better with 65% to 95% achievable within 9 days and more over time.
