How To Make Your Truck Roll Coal?

Do you want to make your truck roll coal? It’s not as difficult as you might think! This blog post will discuss the basics of making your truck roll coal and some tips to get the best results. We’ll also cover some of the people’s most common mistakes when trying to roll coal. So, if you’re ready to learn how to make your truck roll coal, keep reading!

Roll coal is a process of burning fuel in your truck’s engine to create a smoky exhaust. This is done by adding extra diesel fuel to the engine, which increases the amount of smoke that is produced.

To make your truck roll coal, you will need:

  • A truck with a diesel engine
  • Extra diesel fuel
  • A way to add extra diesel fuel to the engine (such as a funnel or syringe)
  • A method of igniting the fuel (such as a lighter or match)

Adding extra diesel fuel to the engine is the most important part of making your truck roll coal. You need to add enough fuel so that the engine will produce a lot of smoke, but not so much that the engine will stall or produce too much power.

One way to add extra diesel fuel to the engine is to use a funnel. Pour the extra diesel fuel into the funnel and then carefully pour it into the engine. Another way to add extra diesel fuel to the engine is using a syringe. Insert the syringe into the engine and slowly add the extra diesel fuel.

Once you have added the extra diesel fuel to the engine, it’s time to ignite it. You can use a lighter or a match to do this.

Hold the flame near the exhaust pipe and wait for the smoke to start coming out. If everything goes according to plan, your truck should now be rolling coal!


Can You Make a Gas Truck Roll Coal?

You might be wondering if you can make a gas truck roll coal. The answer is yes, but it’s not as common because diesel engines produce more smoke than gas engines. However, it is possible to make a gas truck roll coal by adding extra fuel to the engine and then igniting it.

Keep in mind that you should only attempt to make your truck roll coal if it is in good condition and you know what you’re doing. Otherwise, you could damage your engine or cause other problems. If you’re not sure how to make your truck roll coal, we recommend asking a professional for help.

Does Rolling Coal Hurt the Engine?

Rolling coal is the practice of modifying a diesel engine to make it spew black smoke. The Environmental Protection Agency says this wastes fuel and harms the environment. In fact, many people who opt to modify their engines in this way do so because they want to take an anti-environmentalism stance. Some drivers even use coal-rolling as a form of protest against environmental regulations. Regardless of the motivation, coal-rolling emissions can harm both human health and the environment. The soot released by coal-rolling can contain harmful pollutants like particulate matter and nitrogen oxides. These pollutants can aggravate respiratory problems and contribute to smog formation.

Coal-rolling also wastes fuel, which means that engines are less efficient and release more greenhouse gases into the atmosphere. Ultimately, rolling coal is a harmful practice that should be avoided for the sake of both human health and the environment.

Can You Roll Coal With Stock Exhaust?

As any coal roller knows, the exhaust is one of the most important aspects of the truck. After all, the whole point of rolling coal is to create a big, black cloud of smoke. That’s why most coal rollers use aftermarket exhaust systems with big, chimney-style stacks. While it’s possible to get away with using the stock exhaust, it doesn’t make much of a statement.

Plus, aftermarket exhausts tend to be louder, which is another important part of the coal rolling experience. So if you’re serious about coal rolling, you’ll need to invest in a good aftermarket exhaust system.

Is Rolling Coal Illegal in the US?

Rolling coal is the practice of purposely blowing thick black smoke from a truck’s tailpipe. Some people do it for fun, while others see it as a way to protest against environmental regulations. Either way, it’s become a controversial issue in recent years. So, is rolling coal actually illegal in the United States? The answer isn’t entirely clear. While a handful of states have passed laws specifically prohibiting the practice, it’s generally not against the law to roll coal. However, there are other laws that truck drivers could potentially be violating when they roll coal.

For example, many states have pollution control laws prohibiting vehicles from emitting excessive pollution. As a result, rolling coal could theoretically lead to a truck driver being cited for violating these laws. Additionally, some localities have their own ordinances that ban or restrict rolling coal. So, while it’s not necessarily illegal to roll coal across the country, there are definitely some places where it’s not allowed.

How Do You Modify a Diesel To Roll Coal?

In order to modify a diesel truck to roll coal, there are a few different things that can be done. One way is to install bigger injectors. Injectors pump large amounts of fuel into the engine during each injection cycle, and by installing bigger injectors, more fuel will be pumped into the engine which will cause the truck to roll coal.

Another way to modify a diesel truck to roll coal is by aggressively custom-tuning the truck. This involves fooling your engine into wanting more fuel than it actually needs. This can be done by changing the fuel map and increasing the fuel injected into the engine. By doing this, the truck will consume more fuel and will produce more emissions, causing it to roll coal.


Rolling coal is the process of intentionally releasing black smoke from a truck’s tailpipe. While some people do it for fun, it can be harmful to both human health and the environment. Additionally, rolling coal is often illegal in many states and localities. If you’re interested in modifying your diesel truck to roll coal, there are a few different ways that you can do it. Just make sure to check your local laws before you start blowing black smoke everywhere.
