Are you having car troubles? While there are a ton of issues that can negatively impact a car’s performance, there’s a common, yet often overlooked issue: the quality of the gas. Bad gas in your car can cause a number of problems. Below, we highlight some of the telltale warning signs that you should be on the lookout for that indicate your car has bad gasoline.

How Does Your Car Act When You Get Bad Gas?

Discovering that you’ve filled your car with bad gas can be a frustrating experience, as it can have negative effects on your vehicle’s fuel system.

When you pump contaminated gasoline into your fuel tank, it introduces impurities and unwanted substances into the fuel system. These impurities can clog the fuel filter, impact your fuel injectors and potentially reach the combustion chamber, where they disrupt the proper fuel-air mixture necessary for efficient engine performance.

The consequences of bad gas may range from a decrease in fuel efficiency to more severe issues that can result in a hefty repair bill. If you suspect bad fuel is causing trouble, addressing it promptly can help prevent further damage to your vehicle.

Illuminated Check Engine Light

The check engine light lets you know that there is something wrong with the engine. Gas makes its way into the engine, so when it’s bad, the check engine light will inevitably go on. It’s important to note, however, that there are many reasons why a check engine light might go on, so make sure you have your vehicle inspected by a professional to determine if it is a symptom of bad gas or if there is another cause.

Stalling

If you’re driving along just fine and then suddenly, your car stalls out, the gas in your tank could be to blame. Bad fuel hinders complete combustion, , causing the engine to struggle or shut off unexpectedly. When fuel quality is compromised, your vehicle may not receive the consistent power it needs, leading to vehicle stalling and potential safety concerns.

Acceleration Problems

When you push the gas pedal, the engine should immediately respond. If it seems like your vehicle is hesitating to accelerate, you might have a bad tank of gasoline. When the gas is bad, you’ll likely notice more trouble the higher the speed you attempt to travel. If the gas is really bad, there’s a chance that your car won’t accelerate at all.

Using More Gas

One of the common signs of bad gas in a car is a sudden drop in fuel efficiency. Contaminated fuel can lead to poor combustion within the engine, affecting its ability to convert fuel into energy efficiently. As a result, your car may burn more gas than usual, leading to increased fuel consumption and higher costs at the pump.

Engine Sputtering

Your car’s engine may start sputtering or misfiring because of the irregular fuel supply caused by impurities in the gas. If you suspect bad gas, addressing the issue promptly is crucial. Start by checking the gas cap for proper sealing to prevent further exposure to fuel vapors and contamination. However, if you’re experiencing persistent problems, it’s advisable to consult an auto mechanic near you to diagnose and fix the problem. Possible solutions may include a fuel system flush, replacing the fuel filter, or repairs to the fuel filter.
