That's Waste Vegetable Oil.

I have a 1985 Mercedes 190D that runs pure WVO. It has over 800K miles on it. The lubricity of the vegetable oil seems to keep it happy.

I have a 2005 Dodge Cummins 3500 that runs between 5-45% WVO and it seems happy at 250K miles.

Yes, both vehicles have fuel systems I have engineered for their particular designs but both seem to run better with the higher lubricity WVO as fuel or fuel additive.
