Can Bad Fuel in Your Car Illuminate Check Engine?

Introduction

When the check engine light illuminates on your dashboard, it’s a sign that something is wrong with your car’s engine. While there are many potential causes for this, one of the most common is bad fuel.

Bad fuel can damage your car’s engine in a number of ways. It can cause the engine to run rough, misfire, or even stall. It can also lead to decreased fuel economy and increased emissions.

In some cases, bad fuel can also illuminate the check engine light. This is because bad fuel can damage the oxygen sensors in your car’s exhaust system.

How Does Bad Fuel Damage Oxygen Sensors?

Oxygen sensors are responsible for measuring the amount of oxygen in your car’s exhaust. This information is used by the engine computer to adjust the air-fuel mixture.

Bad fuel can damage oxygen sensors in a number of ways. It can cause the sensors to become fouled with deposits, which can prevent them from accurately measuring the amount of oxygen in the exhaust.

Bad fuel can also cause the oxygen sensors to fail prematurely. This can lead to a number of problems, including:

* Rough idle
* Misfires
* Stalling
* Decreased fuel economy
* Increased emissions
