Test Kit Instructions - AFTK: Gas Alcohol Fuel Testing
Before use, remove yellow plastic probe inside test tube; Probe is included for aircraft use to obtain sample from quick drain valves.
Obtain sample of gasoline from tank or gas pump.
(A squirt tip clear dispensor bottle is provided).
- Visualize gas -
Fresh gas appears clear (not cloudy), straw-colored and without any visible sediment or particles. E85 is lighter, almost colorless.
ADD water to “WATER” level line on tester (test tube).
(Water amount is about 1 teaspoon/8cc).
ADD fuel exactly to the “GAS” line, located in upper portion of tube.
(Gasoline amount is about 1 tablespoon/18 cc).
ADD fuel to the gasoline line.
(Amount fuel= Approx. 2 Tablespoons).
STEP 3A (optional)
ADD 1 drop Quik-Check™ indicator solution (QCS) to
enable easier viewing of separation line.
INSERT rubber stopper and shake vigorously for about 30 seconds.
HOLD upright and let stand until liquid settles.
Usually takes about 2-3 minutes, but may take up to 10 minutes.
STEP 6. – READ RESULTS –
LOCATE the gasoline/water separation line and READ the scale.
The marking at level of separation indicates the percentage of alcohol present.
Raised markings are in 5% increments from 0 to 30%. (E0 to E30).
Removable labels are available on request for reading from 30 to 100%.
Perform testing in a well ventilated area, away from heat, fire and open flame - Gasoline is highly flammable.
Most auto and marine engines can tolerate up to 10% ethanol alcohol in fuel, which is the federal and state legal limit for E10 gasoline. Check your state fuel laws for more information. Review U.S. Renewable Fuel Standards (RFS). E15 is now being sold (2012).
Warning: Many fuel additives marketed and purchased by consumers contain ethanol and other types of alcohol.
Always check ingredients (MSDS) before adding any type of fuel additive to your fuel tank.

- A clear dispenser bottle is included to collect gas directly from gas pump nozzle.
- Wear disposable gloves (1 pair included) when testing, to prevent spillage on your hands.
- Removable E100 label is available (by request) for reading up to 100% ethanol. (Note: It is about 3mm between each 5% raised marking on tube).
- "Yellow probe" packaged in tester and screwdriver tip (reversible phillips and flat-head) is used for testing fuel from aircraft engines; Probe is like a key to push up lever/needle valve to drain fuel.
Screwdriver can be twisted off and removed; Although not need by most for testing, it does come in handy when you keep tester in glove compartment or with engine, for other use.
