Normally, fuel meant for car engines is usually refined specifically for the operation of internal combustion engines. Any sort of contamination whatsoever will always make a vehicle’s engine suffer and result in lower overall vehicle performance. Contamination in this context is not so specific rather it could mean virtually any foreign substance that doesn’t belong in the fuel, e.g. water. Out of a vast majority of fuel contaminants, water has been known to be among the top ones.

There are numerous reasons as to why water gets into or mixed with the fuel in the gas tank but condensation is one of the top reasons so far. People that live in cold regions get to experience this condensation issue more than everyone else. Also, it is possible that there was water already in the gas pump as at the time that you were filling up the tank at the gas station.

In some cases, the gas stations themselves might even be the one with a damaged water filter that is doing a bad job of not efficiently filtering out water from the fuel. There is absolutely nothing you could do in such a scenario than to change your filling station but apart from water, leaving a car parked for years or even months, the fuel inside can go bad/contaminated.

These 5 signs of bad fuel below are clear indications for you to check your car gas tank at any point;

1. Acceleration issues
If you start to notice hesitation for your car’s engine in such a scenario whereby no matter how hard you pump the gas pedal, the car just won’t accelerate at all. You will also observe that no matter how you apply tricks to move such a car, the faster you try going, the more obvious this problem will become.

2. Speed changes being abnormal
Bad fuel can not only cause acceleration issues but also cause spontaneous speed changes when you are driving an affected car. You might realize that even when you barely have your foot on the vehicle’s gas pedal, the driving speed still changes drastically. This is one clear indication that you’ve got bad fuel sitting in your gas tank.

3. Fuel filter getting damaged
Normally, a fuel filter in a car is the one responsible for keeping away debris and dirt and making sure that they don’t find their way into the gas tank to contaminate the fuel. So, in a case whereby you realize that your fuel filter keeps getting damaged, you should know that you are keeping excessively bad/contaminated fuel in the gas tank which is hampering the health of the fuel filters.

4. Engine refuses to run
It might happen that, you were driving and then, suddenly the engine stops running. Before you start suspecting other unrelated components, it could be that the fuel in your car is bad or contaminated.

All internal combustion engines will only burn a good fuel in order to generate power for a vehicle. So, when the fuel is bad, the engine will not be able to burn it to generate power and as a result, the engine might just completely refuse to run even on a full tank.

5. Facing troubles when starting the engine
If the fuel in your car is excessively contaminated with water or other foreign substance, then, you might be facing lots of trouble when trying to start up the engine.
