So based on a random articles I found in internet, mass density of vegetable oil is around 900kg/m^3, and gasoline 800kg/m^3, and since we know that E (energy) equals to m (mass) times c^2 (speed of light squared), we can tell that veggie oil indeed is more energy dense than gasoline.
Since used vegetable oil can be used in place of diesel, I’d guess vegetable oil is more energy dense than gasoline…
