If you think you have bad gasoline, there are a few tests you can do to find out for sure. One way is to pour a small amount of gas into a clean glass jar and let it sit for awhile. If there are any impurities in the gas, they will settle at the bottom of the jar.

Another test is to mix the gas with some engine oil and see if it forms clumps. Clumping is an indication of water in the gas. Finally, you can try starting your engine after adding a small amount of fresh gas to see if it runs better.

If it does, then you know the old gas was bad.

  • Before testing for bad gasoline, it is important to ensure that the fuel tank is at least half full
  • This will help to avoid any potential issues with the fuel pump
  • Next, start the engine and let it idle for a few minutes
  • Pay attention to the engine sound and performance during this time
  • If you notice any unusual sounds or performance issues, turn off the engine and open the hood
  • Check to see if there are any signs of leaks or damage around the fuel system components
  • Once you have determined that there are no leaks or damage, restart the engine and let it idle again
  • This time, use a code reader to check for any diagnostic trouble codes (DTCs)
  • If there are any DTCs related to the fuel system, this could indicate a problem with the gas itself
  • Finally, if you suspect that there may be something wrong with the gas but cannot find anything definitive, you can always have it tested by a professional laboratory
