You may have heard the old legend that if you put sugar in someone’s gas tank, you can ruin their car’s engine. But is there any truth to this claim, or is it just a myth that has been perpetuated for decades? The answer is: it’s a myth. Sugar does not destroy a car’s engine, and here’s why.
Sugar is an organic compound, and organic compounds don’t dissolve in petroleum products. This means that sugar will not mix with gasoline, and it will not enter the fuel system. Instead, it will sink to the bottom of the gas tank, where it will stay until it is removed.
The only way sugar could cause any damage to a car is by clogging the filters that are designed to prevent any debris from reaching the engine. However, this is not a serious problem, and it can be easily fixed by cleaning or replacing the filters. As Mike Allen, senior editor at Popular Mechanics, explains: “Sugar is one of those things that sounds like it should work, but it doesn’t. It’s a myth that has been around for decades, but it has no basis in reality.”
The idea that sugar could disable a car comes from the notion that sugar will melt in the gasoline and then caramelize on the cylinder walls. But that’s not what happens. As Jason Torchinsky, senior editor at Jalopnik, says: “The only way sugar could really hurt an engine is if you opened up the air intake and poured sugar directly into the cylinders. And that would be a very bad idea.”
There is also no scientific evidence that sugar can cause corrosion, rust, or any other chemical reaction in a car’s engine. Sugar is simply inert in gasoline, and it does not affect the performance or efficiency of the car.
So what could actually harm a car’s engine? Well, there are some substances that could interfere with the combustion process and damage the engine components. For example, water or gasoline in a diesel engine could cause more harm than sugar, as they could cause knocking, misfiring, or even engine failure. As Ben Stewart, automotive expert at Car and Driver, warns: “Water or gasoline in a diesel engine could cause more harm than sugar, as they could interfere with the combustion process and damage the engine components.”
So next time you hear someone say that sugar can ruin a car’s engine, you can tell them that it’s a myth that has been busted by science. Sugar in the gas tank is not a menace, but a harmless prank. However, it’s still not a nice thing to do to someone’s car, so don’t try it at home.
