DEF is the acronym for Diesel Exhaust Fluid. Every diesel truck that has been made since 2010 is required to use it. It's a product made of 32.5% urea (made from natural gas) and 37.5% de-ionized water. DEF is kept in a separate tank in the truck and the trucks using it will not start unless the DEF system is working properly. There are regulators inside the engine that mix DEF with the diesel exhaust to reduce diesel emissions. That's the purpose of DEF....
And here's the bottom line:
"Unless the nation's truckers can refill with Diesel Exhaust Fluid, the trucks will stop. Literally. DEF production is about to crater and the country's largest truck-fueling company, Flying J, has been directed by Union Pacific railroad to decrease its DEF-receiving shipments by 50 percent or be 100 percent embargoed. Unless resolved, this demand may cause countless thousands of 18-wheelers to be force-parked very soon, perhaps starting this month....
Union Pacific's largest two shareholders are Vanguard and BlackRock. Vanguard's largest shareholder is BlackRock. BlackRock's key figure for strategy and policy is Tom Donilon, President Obama’s former National Security Advisor. Donilon's wife, daughter, and brother work at the Biden White House.
There is no wand to be waved to make the DEF shortage simply disappear. But doing nothing is both reprehensible and indefensible. There is no one better positioned to bring this looming catastrophe to the front burner than two men and two women named Donilon. Yet nothing is exactly what is being done. Why? Well, draw your own conclusions:"
