Diesel engines are in widespread use in many types of vehicles, including SUVs, trucks, buses, and boats. However, a common mistake that diesel vehicle owners make is to put diesel fuel in a gas-powered car. If you are one of these individuals, you should be aware of the consequences of putting diesel in a gas-powered car. In this blog post, we will discuss what happens when you put diesel in a gas-powered car, list the common signs of fuel contamination, and provide recommendations on how to avoid this mistake.

Effects of Diesel Fuel in Gas-Powered Cars

Diesel fuel is denser and has more lubricating properties than gasoline. When diesel fuel is mistakenly put into a gasoline engine, it causes several problems:

  • It does not burn as easily and can result in a slower, rough engine start or a stalled engine.
  • The fuel injectors get clogged, reducing engine power.
  • The fuel pump and fuel lines can become damaged, requiring extensive repairs.
  • The longer the diesel fuel sits in the gasoline engine, the more the damage becomes.

Common Signs of Fuel Contamination

The following are common warnings of fuel contamination after pouring diesel fuel into a gas engine:

  • The engine seems fine for the first few seconds or minutes, then loses momentum.
  • The engine does not start, and any mechanical noise is absent.
  • The Check Engine light comes on.
  • The car emits black smoke and gives a strong odor.

Steps to Avoid Fuel Contamination

To prevent the wrong fuel from entering the gas engine, here are some steps to take:

  • Double-check the pump handle before you begin fueling.
  • If you’re driving someone else’s car, inquire earlier or during the drive the kind of fuel it demands.
  • Do not, under any circumstances, try to change the fuel yourself.
  • Always use caution when you are pouring fuel into gas engines.

How to Fix a Fuel Contamination Problem

It is best to go one of these two routes if you add diesel to your gasoline engine:

  • Pump out the gas tank and clean the tank by filling it back up with gasoline.
  • Alternatively, you can have a mechanic flush out the fuel system by taking the vehicle to a repair shop. They will power flush the fuel system’s parts to clean it up, after which they will refill it with gas.

Consequences of Putting Diesel in a Gas-Powered Car

To conclude, putting diesel fuel in your gasoline-powered car is a significant mistake that can harm your vehicle’s engine and incur a significant repair cost. If you have made this mistake or suspect it, avoid driving the vehicle. Further damage, in addition to the fuel contamination, may result. Contact your mechanic or tow your vehicle to a nearby repair garage. In summary, always double-check the label on the gas pump handle and prioritize your car’s fuel type to keep it running without any damage done.
