I saw an ad in a magazine for G Oil a biodegradable motor oil. Green Earth Technologies (GET) makes and sells this biodegradable motor oil from American sourced beef tallow (or so they claim). GET claims that the API has certified this oil with an “SM” rating. They also sell a full line of other automotive and lawn and garden products that they say are earth friendly.
Do you have any info on this? Is this the real thing or just beef tallow bullshit?
Unlike some of our Best and Brightest, I am no expert on petroleum. But I’ll get the ball rolling, putting two and two together. First, GET’s oil meets or exceeds requirements of API SM, so it doesn’t completely suck. This sets the performance “floor” for an oil, a less than reassuring concept for any (non-leased) car powered by a remotely modern engine design.
More to the point, it’s a floor and not a ceiling: kinda like state-mandated standardized testing thresholds for high school students. So even if you make the grade, you’re probably not Ivy League material. For better or worse, of course.
And the OEM’s know it: Wikipedia notes that several automakers diverged from API’s low ball standards back in the early 1990s. Try VW’s high mileage service intervals on beef tallow-based oil: forget about sludging problems, the oil pan would be lined with metal shavings well before that!
Buyer beware: avoid a “green oil” until an OEM approves it for use in their cars. Not that I hate the environment, but protecting the “Federal Green” in your wallet is no laughing matter. Which is why I do what I do.
