Have you ever put diesel in your gas engine by mistake? If so, you’re not alone. It’s a common mistake that many people make, and it can cause serious damage to your engine if you don’t address it immediately. In this guide, we’ll show you how to fix diesel in a gas engine so you can get back on the road again.
What Happens When You Put Diesel in a Gas Engine?
Putting diesel fuel in a gas engine can cause a variety of problems. Diesel fuel is thicker and has a higher viscosity than gasoline, which means it doesn’t burn as easily. This can cause your engine to misfire or not start at all. It can also cause damage to your fuel system, including your fuel pump, injectors, and filters. Additionally, diesel fuel doesn’t have the same lubricating properties as gasoline, which can cause increased wear and tear on your engine.
Steps to Fix Diesel in a Gas Engine
Step 1: Don’t Start Your Engine
The first thing you should do if you’ve put diesel in your gas engine is to not start your engine. Starting your engine can cause the diesel fuel to circulate through your fuel system, which can cause even more damage. Instead, have your car towed to a mechanic or service center.
Step 2: Drain Your Fuel Tank
The next step is to drain your fuel tank. This can be a messy and time-consuming process, but it’s necessary to get all of the diesel fuel out of your tank. You’ll need to disconnect the fuel line and drain the fuel into a container. Once the tank is empty, you’ll need to flush it with gasoline to remove any remaining diesel fuel.
Step 3: Replace Your Fuel Filter
After you’ve drained your fuel tank, you’ll need to replace your fuel filter. Diesel fuel can clog your fuel filter, which can cause your engine to run poorly or not start at all. It’s best to replace your fuel filter to ensure that your engine is running smoothly.
Step 4: Flush Your Fuel System
Once you’ve replaced your fuel filter, you’ll need to flush your fuel system. This involves running gasoline through your fuel system to remove any remaining diesel fuel. You’ll also need to clean your fuel injectors to ensure that they’re working properly.
Step 5: Check Your Spark Plugs
After you’ve flushed your fuel system, you’ll need to check your spark plugs. Diesel fuel can cause your spark plugs to foul, which can cause your engine to run poorly or not start at all. You may need to replace your spark plugs if they’re damaged or fouled.
Step 6: Test Your Engine
Once you’ve completed all of the steps above, you’ll need to test your engine to ensure that it’s running properly. Start your engine and let it idle for a few minutes. If everything sounds and feels normal, take your car for a test drive to make sure everything is working as it should.
Preventing Diesel in a Gas Engine
The best way to prevent putting diesel in your gas engine is to be careful when refueling your car. Always double-check that you’re using the correct fuel before you start pumping. If you’re not sure, ask an attendant for help. Additionally, make sure you know what type of fuel your car requires and always stick to that type of fuel.
Putting diesel in a gas engine can be a costly mistake, but it’s not the end of the world. By following the steps outlined in this guide, you can fix diesel in a gas engine and get your car back on the road again. Remember to be careful when refueling your car to prevent this mistake from happening in the future.
