I never thought I’d see this one (BrE for AmE “gasoline” or “gas”) in these parts. Even the OED flatly states, “This sense is not in use in the U.S. and Canada,” which doesn’t leave much room for discussion. Google’s Ngram Viewer bears this out, showing use in American books of “gas,” “gasoline,” and “petrol.” I’d wager that the lion’s share of the “petrol” uses are in American editions of British books, or in dialogue spoken by a British person. (Bear in mind that “gas” includes references not only to the fuel but to substances that aren’t solid or liquid.)
But look what just showed up in an e-mail from the very American Sierra Club.
I checked the New York Times and found that the newspaper used “petrol” 32 times in 2018-19. But in all but one or two case it’s said or written by a Brit, Australian, etc. The One exception is a reference to Texas-brewed beer: “a musty, petrol-y offering aged with Texan white-wine grapes.” I imagine it was used here because “gassy” means something very different indeed.
