Diagnostic Test

PREPARE THE GRADUATED CYLINDER FOR TESTING
NOTE:
You will be putting a total volume of 110 ml in the graduated cylinder in this test.
1. Measure the distance between the 90 ml mark and 100 ml mark on the graduated cylinder.
2. Measure that distance just taken above the 100 ml line and make a mark on the graduated cylinder.
  NOTE:
  This will be your 110 ml line for the test.
  - Go To 2
FILL THE GRADUATED CYLINDER WITH WATER AND GASOLINE
NOTE:
It is important to put an accurate amount in during this step in order for the results to be accurate.
1. Put gasoline into the cylinder up to the 100 ml line.
2. Add water to the graduated cylinder until the 110 ml line is reached.
  - Go To 3
MIX THE WATER AND GASOLINE
NOTE:
Securely block the top of the graduated cylinder to prevent spilling during this step.
1. Thoroughly shake and mix the water and gasoline in the graduated cylinder.
2. Set the graduated cylinder down and allow the clear water/ethanol mixture to settle to the bottom.
  NOTE:
  The clear fluid that settles to the bottom will be a water/ethanol mixture. Subtract the 10 ml of water that was added from total volume of the clear fluid and the difference is the ethanol level.
  
  NOTE:
  The maximum ethanol level for an E85 vehicle is 85% alcohol. The maximum ethanol level for a non - E85 vehicle is 10%.
  
  Is the ethanol level correct for the vehicle?
  
  Yes
  - Test complete.
  No
  - Replace with the proper fuel.
