Think of crude oil as a thick, stinky black smoothie. Refineries are like magical blenders that split it into parts. Petrol comes out first. Diesel comes out later. Simple, right? Wrong.
The problem is demand. The world is addicted to diesel for trucks, trains, and ships. We use way more diesel than petrol for heavy lifting. But refineries are designed to make more petrol. It’s a classic supply-and-demand face-off.
Diesel demand skyrockets while supply limps behind. Basic economics kicks in: less supply + high demand = you pay more. It’s like trying to buy avocado toast during a brunch rush.
A Quirky Fact: The Ketchup Bottle Analogy
Ever fight with a ketchup bottle? You bang the bottom, and suddenly a huge blob explodes out. That’s diesel refining. The process is stickier and more energy-intensive. It costs more to make. Every. Single. Drop.
Diesel molecules are longer and heavier than petrol ones. They need more heat, more pressure, and more fancy chemistry to crack them open. Your wallet feels that extra energy burn.
