Mexican federal authorities have seized more than 1 million liters of fuel after dismantling four illegal processing centers across three states, the Federal Attorney General's Office (FGR) announced Tuesday.

The operation targets the entrenched 'huachicol' network, which siphons crude from state-owned Pemex pipelines for illicit refining and sale.

The crackdown represents a sustained effort by the government to curb fuel theft, which has historically drained billions of pesos from Pemex and distorted domestic energy markets.

By removing clandestine refineries, authorities aim to reduce the supply of cheap, untaxed fuel that undercuts legitimate distributors and erodes the state oil company's cash flow.

This development follows a similar operation earlier this week, in which officials dismantled four other clandestine refineries and seized approximately 6,300 barrels of petroleum derivatives. The frequency of these raids suggests a coordinated escalation in enforcement against the illegal fuel trade.

While the immediate volume seized is modest relative to national consumption, the persistent disruption of processing infrastructure poses a long-term risk to organized crime groups reliant on fuel theft.
