All drivers out there, listen up! Are you sick of your blinkers behaving strangely? Do they stay on even after you change your lane? Do they function properly only when they feel like it? In that case, you may want to check the blinker fluid level. Yes, you didn’t read it wrong! Much like your engine requires oil and your brakes require brake fluid, your blinker also needs its own fluid to work smoothly. What, so you have never heard about this mysterious substance? Is the blinker fluid real,” you ask?

For those wondering, “What is blinker fluid used for?”, here is a basic knowledge: It’s a liquid that keeps your turn signal light working properly. While some people say blinker fluid can lubricate the car’s transmission or keep the brakes in good condition, these are actually not true. The blinker fluid’s only purpose is to assist the blinker’s function. 

While it might seem humble, the blinker fluid has a fascinating history. Sir Steven Stevenson invented it –  or you might say, one of the most incredible mechanics in England. Famous for his ground-breaking work in the vehicle repair industry, he is well-known by almost every car enthusiast. 

One day, Sir Steven was dealing with a car whose headlights had a stubborn blinking issue. No matter what he did, the headlight kept on blinking. “A pair of headlights can’t take me down,” the great Steven declared. 

And so, he set to work, combining and testing out all sorts of substances, from the most harmless to the most unusual. Many days passed, and finally, Sir Steven proudly held up a bottle of luminous fluid. “Lo and behold, my motorheads,” he yelled out. “I present to you… the blinker fluid!”

As with any invention, the auto world was skeptical at first. Since no one knows how to fix the blinkers, though, other mechanics agreed to give it a shot. To their bewilderment, once the blinker fluid was added, the lights stopped flashing. “By the powers of Merlin!” they shouted, “This thing is unbelievable!”

Nowadays, the blinker fluid is now the ultimate solution for blinking headlights throughout the kingdom. Being hailed as a hero, Sir Steven spends the rest of his life in glory and lives happily ever after.

A remarkable story, isn’t it? Except, well, that it’s all fictitious. Sir Steven is not real, and his blinker fluid never exists. 

When Did It All Start? 

But if “blinker fluid” is not real, where did this term come from? The word first appeared in the Urban Dictionary in 2004, so it has been around for much longer than we think. In 2016, searches for “blinker fluid” rose dramatically and peaked in 2017. Still, the term’s origin remains a mystery. 

What we know is that the hunt for blinker fluid belongs in a joke category called “fool’s errands.” These pranks are usually played by more seasoned members on a rookie, sending the person off on an impossible mission. This leads to a waste of time, as well as embarrassment and frustration.

What Are the Benefits of Using Blinker Fluid? 

Although blinker fluid isn’t an actual product, there are still some benefits to talking about it. The most obvious one is the lightheartedness of the joke. It brings a sense of humor to car maintenance, which can make it more enjoyable for everyone involved. 

The prank also removes some of the pressure that comes with owning and maintaining a vehicle, as it’s just something to laugh about and not take too seriously.

The Fluids Your Car Actually Need

Instead of blinker fluid, what are the “fluids” that really keep your car functioning? Well, take a look at DriveRevolve’s list below! If you keep them in mind, you can avoid being fooled by the prank next time:  

  • Brake fluid
  • Coolant
  • Motor oil
  • Transmission oil 

Brake Fluid

As its name indicates, the brake fluid ensures the brake system’s function. When you press down on the brake pedal, this fluid allows force to be applied, letting your vehicle slow down and ultimately stop. With enough brake fluid, you can recognize when there is uneven wear on brake pads

Since the system constantly generates heat, brake fluid can dry out over time. Not having enough brake fluid means you can lose control of your car’s speed, so it is best to check out the fluid level every 30,000 miles. 


To prevent the engine from being overheated, the coolant absorbs the heat from it, helping it to maintain the right temperature. Some refer to it as antifreeze since this fluid also keeps the engine from freezing in cold weather. That’s why coolant is irreplaceable, even with water

Since it is essential for the engine’s function, experts recommend you top up the coolant regularly. The ideal basis is once every 30,000 miles. 

Motor Oil 

While the coolant keeps the engine running at an appropriate temperature, the motor oil lubricates the parts inside the engine. That way, your car will always function smoothly.

If you drive your car frequently, you should get an oil change once every 3,000-5,000 miles. 

Transmission Oil

Transmission oil prevents wear and tear on moving parts and provides hydraulic pressure to your vehicle. With the help of this fluid, the car can change hears without damaging any component. Lack of transmission fluid will result in more frequent  (and more costly) repairs.  


How Is Blinker Fluid Used in Pop Culture?

Despite blinker fluid not being a real auto part, it has become an integral part of car culture and has been referenced in movies, TV shows, video games, and other popular media. From references in The Simpsons to jokes about topping off the blinker fluid in Family Guy, blinker fluid has become a classic part of pop culture. 

What Cars Use Blinker Fluid? 

No cars ever used blinker fluid. As mentioned earlier, the “mythical auto part” was initially created as a joke and has since become an integral part of car culture. So if you hear someone joking about topping off the blinker fluid, just offer them a friendly smile and enjoy the moment!

How Do You Know When to Top Up Blinker Fluid?

Since blinker fluid isn’t a real auto part, there is no need to top up the supply. Instead, you should focus on maintaining your car regarding actual car parts and maintenance needs. 

What Are Some Potential Problems With Not Having Enough Blinker Fluid?

Not having enough blinker fluid isn’t an actual problem, as it doesn’t exist. However, if you are not regularly maintaining your car with real auto parts, then you may find yourself dealing with various issues related to performance and safety.
