How To Safely Get Rid Of Old Gasoline?

Gasoline is a transportation fuel that is responsible for internal engine combustion. Cars, light trucks, motorbikes, boats, small aircraft, and even construction equipment and electric generators require it to function. After refueling your gasoline, keep on inspecting it after a few months. Old gasoline can harm the internal parts of your engine.

Why Does Gasoline Go Bad?

Age is the main factor that affects gasoline. When gasoline gets exposed to air in your engine, oxidation will occur. With time, the gasoline will start degrading, and the color will change. It gets contaminants that block your fuel system and also the engine. If you don’t replace it on time, it damages your engine’s internal components and sometimes ruins them permanently.

So, how do contaminants enter? A cracked fuel line is one way your gas gets contaminated. Again, if you have a loose gas cap, water is likely to sneak to the gas pump. Since gasoline contains ethanol, when condensation occurs, gasoline will attract the water. That’s why it’s important to change the oil every six months.

Symptoms of Bad Gasoline

Since gasoline helps in combustion, when it goes bad, the combustion process will get affected. As a result, you will get these signs.

  1. Car won’t start – If you have been having challenges starting the car, bad gasoline could be the reason. Though other reasons make your engine fail to start, inspect the gasoline first before getting a solution.
  2. Engine sputtering – What sound does your car produces while idling and when in motion. If it sputters, then you could be having a bad oil filter.
  3. Car stalling – If excess water leaks into your gas pump, then it will interfere with the combustion. Your car will stall when in motion, and it will not accelerate well. Driving up the hill will also be a challenge.
  4. Poor gas efficiency – Your engine has to work harder to produce enough power. That means it will require more fuel than usual.
  5. Change of speed – Is the car maintaining the same speed that you want? If it’s slowing down or even surging of speed abruptly, chances are high the gasoline has a problem.
