WARNING: This page is about a different car, the 2003 Pontiac Grand Am, 2003 Oldsmobile Alero, 2003 Chevrolet Monte Carlo, and 2003 Chevrolet Impala. However, it is still accessible from the selected car via links, so may be relevant.
The fuel sample should be drawn from the bottom of the tank so that any water present in the tank will be detected. The sample should be bright and clear. If alcohol contamination is suspected, use the following procedure to test the fuel quality:
- Fill the cylinder with fuel to the 90 ml mark using a 100 ml specified cylinder with 1 ml graduation marks.
- Add 10 ml of water to bring the total fluid volume to 100 ml and install a stopper.
- Shake the cylinder vigorously for 10-15 seconds.
- Carefully loosen the stopper to release the pressure.
- Install the stopper and shake the cylinder vigorously again for 10-15 seconds.
- Put the cylinder on a level surface for approximately 5 minutes to allow adequate liquid separation.
