Green Earth Technologies have come up with an API approved biodegradable motor oil. What does the API (American Petroleum Institute) mean for us? It means that the product meets the correct specifications to use in our high performance gasoline engine. Even if you still have doubts, know that Green Earth Technologies is running their product with the Gunnar Racing team in ALMS. So chances are it can take the abuse of daily driving abuse.

So what is G-Oil? Manufactured from rendered beef tallow, it has the same molecular structure traditional petroleum-based products. The company states that “it takes three barrels of crude oil to make one barrel of motor oil, but it only takes only one barrel of animal fat to produce one barrel of G-Oil”, which is pretty amazing. Unfortunately there aren’t enough barrels of animal fat to solve the world’s oil problems, but when it comes to lubrication Green Earth Technologies may have the best Green solution out there.

Only question in my mind are the operating temperature ranges for the oil and how many miles do can you go before you need to change the oil.
