Help me... is it fuel or oil?

Hard to say, but I'm guessing fuel.

smell it, or use dye marker, or cinnamon oil in fuel tank if diesel.

picture different brands.

Thanks, I don't see a fuel leak from the top side. I'll have to ramp it and get under while it's running. How much cinammin oil do you put in tank?

Does it make the car smell like Cinnabon rolling down the road?? lol
