How to Get Rid of Bad Gas in a Car: A Comprehensive Guide

As a car owner, there’s nothing more frustrating than experiencing bad gas. It not only affects the performance of your car but can also cause damage to its engine. Bad gas can be caused by several factors, such as old fuel, clogged air filter, and dirty fuel injectors. Thankfully, getting rid of this problem is not difficult, and in this article, we’ll take you through everything you need to know about bad gas and how to avoid it.

What Causes Bad Gas in a Car?

Bad gas is caused by impurities or contaminants in the gasoline that you put into your car’s fuel tank. These impurities can come from various sources, including:

1. Old Fuel

If you don’t drive your car often and leave gasoline sitting in the tank for an extended period, it can become stale and lose its potency. Old fuel can cause poor engine performance, hesitation and stalling.

2. Dirty Fuel Injectors

Fuel injectors are responsible for delivering the right amount of fuel into the combustion chamber; any amount of debris or dirt inside it can block the flow of gasoline. Dirty fuel injectors are a common cause of bad gas.

3. Clogged Air Filter

Your car’s air filter removes dirt and debris so that cleaner air flows into your car’s engine; when it gets clogged up, airflow into your car’s engine gets restricted. This reduces acceleration abilities and causes weak engine performance.

4. Faulty Oxygen Sensor

The oxygen sensor measures the amount of oxygen being burned in your exhaust; if it malfunctions or becomes faulty, it leads to a lean or rich mixture that can affect engine performance.

Symptoms of Bad Gas in a Car

Recognizing symptoms of bad gas is easy; four significant signs are:

1. Poor Fuel Economy

When you realize that you are covering fewer miles than you usually do, it’s usually a sign of bad gas in your car. Poor fuel economy is a sign that your engine is not functioning optimally due to impurities in your gasoline.

2. Engine Misfires

An engine misfire is when the engine doesn’t run smoothly or runs erratically. Misfires occur when fuel fails to ignite in the combustion chamber. This occurs when there’s an insufficient amount of fuel being delivered to the cylinder or when contaminated gasoline causes an improper mixture ratio.

3. Rough Idling

If your car shakes prominently while idle after running, it could indicate bad gas and poor performance of your engine. Rough idling can cause immense damage to your engine’s components, leading to permanent failure.

4. Difficulty Starting the Engine

When your engine struggles to turn over or doesn’t start, it typically indicates a weakened combustion process brought about by bad gas.

How to Prevent Bad Gas in a Car
