If you have accidentally put gasoline in your diesel engine, you may be wondering if it will cause any damage. This is a common mistake, and it can have serious consequences if not addressed properly. In this article, we will explore the question of whether a little gas will hurt a diesel engine and provide you with some helpful tips on what to do if you find yourself in this situation.
Will a little gas hurt a diesel engine?
The short answer is yes, gasoline can harm a diesel engine. The reason for this is that gasoline does not ignite in the same way that diesel fuel does. When gasoline is introduced to a diesel engine, it can cause a number of problems, including:
- Fuel system damage: Gasoline is a solvent that can damage the seals, gaskets, and other components of the fuel system.
- Engine damage: Gasoline does not lubricate the engine as well as diesel fuel, which can cause damage to the engine’s moving parts.
- Performance issues: Gasoline can cause the engine to run poorly, with reduced power and efficiency.
Understanding Diesel Engines and Gasoline:
Before we dive into the question of whether gasoline can harm a diesel engine, it’s important to understand the differences between the two fuels. Diesel fuel is a heavier, oilier fuel that is designed to power diesel engines. Gasoline, on the other hand, is a lighter, more volatile fuel that is designed to power gasoline engines.
Diesel engines work by compressing air in the combustion chamber until it reaches a high temperature. The heat causes the diesel fuel to vaporize and ignite, which generates the power that drives the engine. Gasoline engines, on the other hand, work by using a spark plug to ignite a mixture of gasoline and air in the combustion chamber.

What to Do if You’ve Put Gasoline in Your Diesel Engine?
If you have accidentally put gasoline in your diesel engine, there are a few things you should do immediately:
- Do not start the engine: Starting the engine can cause the gasoline to circulate through the fuel system, which can cause more damage.
- Drain the tank: If you haven’t started the engine, you can simply drain the tank and replace the fuel with diesel. If you have started the engine, you will need to have the fuel system flushed and cleaned by a professional mechanic.
- Replace the fuel filter: Gasoline can clog the fuel filter, so it’s important to replace it if you have accidentally put gasoline in your diesel engine.
- Have the engine inspected: Even if you have drained the tank and replaced the fuel, it’s a good idea to have the engine inspected by a professional mechanic to ensure that there is no lasting damage.
Preventing Accidental Gasoline Contamination
The best way to prevent accidental gasoline contamination is to be mindful when fueling your diesel engine. Make sure that you are using the correct fuel nozzle and pay attention to the color of the pump handle. Diesel fuel pump handles are usually green, while gasoline pump handles are usually black. It’s also a good idea to double-check the fuel grade and type before fueling.
