I think this rumor is about as useful as people who were predicting that bitcoin was going to be $100,000 by the end of 2021.
Yep, or about as useful as most rumors, i.e., pretty much useless to anyone but oil traders who would probably act on it. For the rest of us, there's not much we can do. It's not as though we can stockpile gasoline or heating oil in case the price of both skyrocket. If the rumor was about rice or toilet paper, it might be a different story--but even then, what we're talking about here is just something some internet nobody wrote on a discussion forum with no evidence.
And I'd also point out that you only hear predictions like this when there's already a trend (or what
looks like one) in the price of something. Those predictions about bitcoin going to $100k were usually when it was rising anyway. And then it turned out to be incorrect, so there you go.
