Now, here’s a hilarious fact: gasoline is a dramatic, unstable diva that goes bad in three to six months. It evaporates, gums up carburetors, and generally throws a hissy fit if you look at it wrong. Diesel, on the other hand, is a grumpy, stoic workhorse. It’s oily and less volatile, so it takes longer to go bad.
But diesel’s longevity is a double-edged sword. While gas is a fast-melting ice cube, diesel is a slow-rotting potato. It lasts longer, but when it rots, it rots gross. You can pour old gas into a lawnmower and sometimes get away with it. Pour old, goopy diesel into your truck, and you might be calling a mechanic who will laugh at you (and charge you $500).
