I don't know but he routinely sprays that shitty generic Pam knockoff on his pans when he's "cooking."
Just to compare how shit he is at cooking to another LPer who is also better than him at fucking everything, there's one guy called lethalfrag who does a side cooking series.

Now, you might think it's unfair to compare this to Phil, as the guy actually has a culinary arts degree. However, he tailors it to his audience and generally does things simple enough he might inspire a fellow neckbeard to make some decent food for a change.
But seriously, DSP's cooking videos are so fucking bad I would be embarrassed to cook the garbage he does even drunk in my underwear at 3 in the morning.
