It says the soybean-based chainsaw oil offers high performance while being environmentally safe. Soy oil helps make EnviroLogic 440 biodegradable and nontoxic. Our product will not kill grass or leave a long-term sheen on the water if it seeps into the environment. The soybean-based oil's environmental benefits make it ideal for places where motor oil leakage poses a significant threat to an area's aesthetic appeal. Initially it will be marketed to forest products companies, public lands management agencies, and golf courses.
Soybean oil is naturally a better lubricant than petroleum.
It adheres to metal better, which reduces engine wear. Soy's natural lubricity also reduces the amount of friction in the engine. Less friction enables the engine to run cooler and makes it more efficient. Using soybean oil did pose a few challenges to researchers. When soybean oil is exposed to oxygen, it has a tendency to break down if proper additives and modifiers are not mixed with it.
