Kits are available with or without our exclusive Quik-Checkô Indicator Solution. Quik-Checkô indicator solution instantly reveals alcohol and water in fuel. (Image: Deluxe Kit -Product Code: AFTK-D15).
Right: Non-ethanol gas (no alcohol or water) -
Blue Quik-Check drop(s) settles to bottom, not absorbed.
Left: Quik-Check reveals gas contaminated with alcohol and water (bright blue).
#1 Reason for gas-caused engine damage = Phase-separated E10 gasoline.
- Protect your engines: Test gas for alcohol % + water contamination -
Always test ethanol percent/concentration of fuel at time of purchase,
and especially after prolonged storage.
--> After ethanol absorbs water and gas phase separates, bottom tank layer contains 60-95% alcohol=Damage + Problems! Most common in spring after winter storage, and summer due to high humidity.
- Mercury Marine released a study that revealed a blend of 15 percent ethanol and gasoline caused so much damageto boat engines that the testing of two of three motor types ended early.

FAQ - Frequently Asked Questions
Can I safely use E10 type gas in all my engines?
Answer=It depends on several factors...
Most modern engines are designed to run on ethanol blends up to 10% alcohol. Many older engines (pre-2003) issued warnings against use of gas with ethanol, and parts may not be designed to resist solvent effects of alcohol.
Common symptoms of excess alcohol or water in gas:
Vapor lock and fuel starvation (stalling, hesitation, inability to start engine), corrosion/rusting, premature disintegration of fuel pump, oxygen sensor damage, clogging/plugging of filters, fuel injectors and carburetor, reduced gas MPG... More E10 gas problems/damage...
For prolonged gas storage, it is always safest to leave gas tank empty, when ethanol-free gas is unavailable.
E10 gas will only remain stable (water-free) for a maximum of 3 months, when stored under ideal low humidity conditions.
---> Always check product ingredients before use with E10 fuel type. Most gas additives contain strong solvents, cleansers and/or alcohol, which is contraindicated for use with E10 gas type.
Important: No gas additive can prevent ethanol's natural ability to attract/absorb or remove water in a sedentary engine. Products such as Stabil, only "perk-up" stale fuel by increasing energy content; They do NOT prevent or remove water from gas tank.
After phase separation, most water + alcohol drops to the bottom of the tank -->
Now the lower layer of tank contains an alcohol concentration of 60 to 95%!
* Details 10 Gasoline PHASE SEPARATION: Alcohols attract and absorb water...Oil and water do not mix. Although gas with ethanol may cause varied problems/issues, the #1 reason most engines experience major damage is solely due to running phase-separated fuel, which now has a much higher alcohol concentration at the bottom of the tank + a drop in octane of 2-3 points in the upper tank layer.
10% is the maximum amount of ethanol allowed by all conventional engine manufacturers and warranties. Gas with excess ethanol will absorb MORE WATER, MUCH FASTER.
Warning: E15 (15%) is now being legally sold, but ALL engine manufacturers prohibit use of this new fuel! *Not applicable to FFV's/E85.
Sadly the EPA + ethanol organizations have chosen to ignore all recommendations & research studies
from those who design, sell and repair engines.
Following simple precautions will decrease risk and help safely manage E10 fuel blends.
E10 gas can cause engine damage, poor performance, parts deterioration and lower mpg.
Many gas stations do NOT label gas pump when ethanol is added.
Is the EPA protecting you or the ethanol lobbyists?
BUYER BEWARE: Over 95% of gasoline sold at public gas pumps now contains ethanol=E10.
