The density is much lower. I expect you'd sink.

The density of the body with breath exhaled is about 0.99 to 1.07. The lowest
density with breath deeply inhaled drops to as low as 0.90. Oils are less
dense than 0.90 - yes, you'd sink. Wear your PFD.

What's the density of your PFD? ;)

Mine, I don't know. However the density of polyethylene foam, used for
PFDs, is about 0.03. My density is about .99 (I float with just my face
above water). To float in a fluid of density 0.84 (about that of diesel
oil), I would require a polyethylene PFD that was about 20% of the volume
of my body. That's larger than most PFDs, so I guess I would sink. Wear
*two* PFDs.

I'm kind of curious why this question came up, to begin with.

Oh yeah, and you'd better make sure the PFD is oil-resistant. Petroleum
products dissolve some types of foam, as anyone who has put gasoline in
a styrofoam cup can attest.

That's why I chose polyethylene. Polystyrene would collapse in gasoline,
and besides it is rather brittle.

Re#5 ...well this is how the Q came up.
one of my friend's nightmare is to drown in a large vat of oil....

Do you mean he/she has that as an actual dream/nightmare?
