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. (See image below).
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 less than 1 tablespoon, about 8cc).
ADD fuel exactly to the “GAS” line, located in upper portion of tube.
(Gasoline amount is about 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 E5 E10 E15 E20 E25+ 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 - Beware: 10% is still the maximum amount approved by conventional engine manufacturers!
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.

Quik-Check Solution, a non-toxic indicator dye solution, is very concentrated. Wash immediately with soap and water to prevent permanent discoloration.
Wear disposable gloves (1 pair included) when testing, to prevent spillage on your hands.
Tester has permanent markings up to 30% built into tester - Will last a lifetime. Removable E100 label is available (by request) for reading up to 100% ethanol. E85 + E100.
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.
Clean and dry fuel tester and clear plastic dispenser bottle immediately after use.
Most engine manufacturers still do NOT approve of use of this new fuel type.
It's shocking that the EPA would approve of a gasoline type that is not recommended or approved for use by the engine's manufacturers. Since E15 approved (2010), illegal over-blending of E10 type has worsened.
Ethanol-free is the preferred fuel choice for most specialty engines:
