Unless I drive to a specific gas station to get 100% recycled fuel, the normal diesel only has 10-20% such products, and likely less in summer. It's not nothin

Unless I drive to a specific gas station to get 100% recycled fuel, the normal diesel only has 10-20% such products, and likely less in summer. It's not nothing and certainly better than just a few years ago, but it's still not exactly like a significant fraction of diesels use a significant fraction of vegetable oil.
