This stuff came out in the early 2000's.
Green Earth two-cycle oil, also known as G-OIL, is
a biodegradable, bio-based engine lubricant made from sustainable animal fats (beef, pork, chicken), designed as an eco-friendly alternative to petroleum oils for 2-stroke engines, offering excellent lubricity, low smoke, and high performance at extreme temperatures, meeting API TC standards. It's recognized for being plant-based (in some formulations like NV EARTH) or animal-fat based, offering superior cold-flow and high-temp stability compared to conventional oils, and is easily identified by its green color for proper mixing.
