If your car cranks but won’t start, it could mean that you have bad gas. Your car is difficult to start. As a result, all of the fuel will not burn, which causes black smoke and rotten egg smell.

If the symptoms of the bad gas started after you put less than half of a tank of gas in your car, you can try using a fuel additive or stabilizer that absorbs the water in your gas tank. Oxygen sensors in modern cars analyze exhaust gas levels to monitor the effectiveness of the component. When it comes to symptoms of bad gas, sputtering and even unintentional gear shifting could also mean that your gas quality has been compromised.

If the sensor detects that the gas has not been well converted, the check engine light will illuminate. Your car may run rough. Bad gasoline, which is a term normally used to refer to gasoline that has a high water content or insufficient octane, does not ignite and burn inside the engine cylinders as well as high quality gasoline.

You can also run into problems if you add the wrong gas (like diesel in an unleaded only vehicle). It is because the amount of fuel present in the combustion chamber is higher compared to the air. A major symptom of bad gas is engine pinging, or knocking, which typically occurs as the result of poor or incomplete engine combustion.

Maybe the engine won’t start or it sputters when it should be running like a charm. Top 5 water in gas tank symptoms. For smaller amounts of bad gas:

Your car won’t start or struggles to run. The situation will be very similar to running your car without gas at all. This is a sign that your gas isn’t burning properly or something is interrupting the fuel’s flow to the combustion chamber.

Ignoring bad gas can lead to clogging, stalling, weak engine power and irregular combustion. When gas is tampered with, watered down, or even added to your tank after sitting around for too long, it may be too inefficient to allow for quick changes in gears.

When you have strange discoloration or coloration around your gas tank door cover, you probably are dealing with a failing gas cap.

Since the gas cap cannot seal the tank adequately, fuel fumes escape and deposit on the gas tank opening. Fuel contains a small number of sulfur particles that convert to hydrogen sulfide during combustion. And this makes sense given that the symptoms of stale gas center on poor combustibility of the fuel.

Once the bad gasoline is in the tank, it either has to come back out, or it must be “fixed” in some way. Strange coloration at around your gas tank mouth.
