Consequences of Putting Diesel in a Gas Car

Using the wrong type of fuel in a car can cause serious damage. In this article, we will look at what happens when you accidentally put diesel in a gasoline-powered vehicle.

Damage to Your Car

The most significant consequence of putting diesel in a gas car is the damage that it can do to the vehicle. Diesel fuel is much thicker than gasoline, and too much of it can lead to a number of problems.

  • Clogged fuel filter: The diesel fuel can clog the fuel filter, which will make it difficult for the gasoline to reach the engine. This can lead to reduced engine performance, or even cause it to stall entirely.
  • Fuel pump damage: The diesel fuel can cause damage to the fuel pump, as it is designed for gasoline.
  • Engine damage: If the diesel fuel manages to reach the engine, it can cause serious damage. The diesel fuel is designed to ignite at a higher temperature than gasoline, so it may fail to ignite and cause a build-up of unburnt fuel.

Cost of Repair

Depending on the severity of the damage, repairing a car after putting diesel in it can be expensive. Replacing the fuel filter, fuel pump and other parts of the engine can easily add up to hundreds or even thousands of dollars.


The best way to avoid the expensive repairs and damage caused by putting diesel in a gas car is to be careful and double-check each time you fill up. Always make sure that you are putting the correct type of fuel in your vehicle.
