You’re out on a long road trip and your car starts to run low on fuel. You pull into the nearest gas station, but all they have is diesel. Do you put it in your car and risk ruining your engine, or do you go without filling up? This article will explore what happens when you put diesel fuel in a car that takes gasoline. It also will discuss the potential consequences of doing so and how to avoid them.
Gasoline Vs. Diesel: What’s The Difference?
Before we get into what happens when you put diesel in a car that takes gasoline, let’s first discuss the difference between these two types of fuel. Gasoline is a petroleum product that is refined from crude oil. Diesel fuel is a heavier petroleum product that is also refined from crude oil.
Diesel engines are designed to run on diesel fuel, while gasoline engines are designed to run on gasoline. Diesel fuel is denser than gasoline, and it has a higher energy content. That’s why diesel engines are more efficient than gasoline engines.
What Happens When You Put Diesel In A Car That Takes Gasoline?
If you accidentally put diesel in a car that takes gasoline, the first thing you’ll notice is that the engine will run roughly. The engine may also produce a knocking sound. These are both signs that the engine is not running as efficiently as it should be. So, while it may be tempting to just top off your tank with diesel in a pinch, it’s not worth the risk.
Another immediate consequence of putting diesel in a car that takes gasoline is that the engine likely will stall. This is because diesel is much thicker than gasoline, and the smaller fuel injectors in a gasoline engine can’t handle the increased volume. As a result, the engine will receive too much fuel and will stall.
In addition, running a gasoline engine on diesel can damage engine components. The high-pressure fuel injectors in a diesel engine are designed to withstand the higher pressures associated with diesel fuel. However, gasoline injectors are not built to withstand these same high pressures, and as a result, they can be damaged when used with diesel fuel.
How to Avoid Putting Diesel in a Car That Takes Gasoline
Now that we’ve seen what can happen if you put diesel in a car that takes gasoline, let’s discuss how to avoid this mistake.
The best way to avoid putting diesel in a car that takes gasoline is to familiarize yourself with the different types of fuel pumps at the gas station. Gasoline pumps are typically yellow, while diesel pumps are usually green or black. Also, most gas stations have three options for gasoline and just one for diesel, so when in doubt, don’t pick up the fuel pump that’s separate from the other three. If you’re unsure which type of fuel pump you should use, ask a gas station attendant for help.
What Should You Do After Putting Diesel in a Gasoline Engine?
If you do accidentally put diesel in your car, the best thing to do is to have it towed to a nearby service station or mechanic. They’ll be able to drain the fuel tank and flush the system with gasoline, saving your engine from further damage.
