A viral rumor claimed Donald Trump advised truckers to switch from diesel to gasoline as a way to cut fuel costs. Snopes investigated and confirmed the claim originated from a satirical post on Fazzler.com — a website known for publishing fictional, joke news stories — and was never a real statement made by Trump.
Multiple credible news outlets that covered Trump's actual fuel-cost responses in the same period, including Al Jazeera, Transport Topics, KIRO 7, and CBS Evening News, reported on measures like a temporary Jones Act waiver to lower oil and gas transport costs. None recorded any suggestion about truckers switching fuels. Trump did publicly address rising fuel prices, predicting they would come down, but the diesel-to-gasoline advice never happened.
Beyond the lack of evidence, the claim is also technically nonsensical: diesel engines cannot simply run on gasoline. The two fuels use fundamentally different combustion mechanisms, and running gasoline through a diesel engine would cause serious mechanical damage. This technical impossibility is a common red flag that helps identify the claim as satire rather than a real policy suggestion.
