What is Ethanol?
is a member of the alcohol family and is one of the
alternative fuels for gasoline. Anhydrous ethanol
(meaning without water) usually has water content of ½
percent or less and is currently the only ethanol that
can be safely blended with gasoline.
Hydrated ethanol (up to 4% water) will not safely blend
with high concentrations of gasoline but can be used in
pure forms as a substitute for gasoline. (E-85)
Ethanol is a renewable fuel and can be made from a wide
variety of crops and vegetation including sugarcane,
corn, sugar beets, Etc. However one of the highest
yields is from sugarcane. It can also be made from coal,
natural gas and other petroleum products but that
defeats the intent of decreasing foreign oil dependency
and air pollution. The newest experimental technology is
an ultra-high yield Algae for ethanol and bio-diesel
production. The net yield/energy return ration is higher
than existing methods. (More than 15 to 1)
What engines can safely use it?
Ethanol blends of up to 10% (E10) can be used in any
gasoline engine without modification. However we racers
blended E10 for our tow vehicles back in the 70’s & 80’s
and found that extended use caused some rubber and
plastic hoses and carburetor gaskets to swell, dry and
crack or dissolve especially if they were already a bit
old or worn. Today, many newer hoses and components are
now compatible with ethanol/methanol and will usually be
marked or labeled accordingly.
If your fuel blend is
over 10% (E20, E30, E50, Etc.) it cannot be safely used
unless your vehicle has a flexi-fuel engine or you
modify your fuel system accordingly. (Flexi-fuels are
usually E20 or higher) The reason for this is your
engine needs a higher volume of ethanol fuels as
compared to pure gasoline. Yes, that translates into a
slight decrease in fuel mileage. (10%-15%) After each
race we blended our left over racing ethanol with
gasoline and used it in our tow vehicles. We found that
a 10% blend decreased our mileage by 10-20 percent.
However we could
increase the ignition timing to get a horsepower boost
of 5-10%. (Great for towing in mountain areas)
Ethanol fuel handling and storage:
First, it will quickly absorb any available
free-water from the bottom of a tank and even absorb
moisture right out of the air in a very short period.
(Called a wicking action) That can have an immediate
effect and result in a loss of 5-15 octane points
evidenced by valve pinging, if not treated it will soon
lead to fuel separation. (Stratifying) The water usually
settles to the bottom of the tank and forms a milky
mucous looking slime. Second, we found ethanol and
methanol has a very high detergent action (cleaning)
that is many times more powerful than pure gasoline.
Therefore it quickly removes varnish, scale and oxides
from the walls and bottom of tanks that accumulates in
the fuel system in the form of slime and crud that can
clog fuel filters, carburetors and injectors.
Fuel Service recommends replacing all fiberglass
tanks before using or storing ethanol fuels. For
metal or plastic tanks more than 1-year old you should
clean your tanks and remove scale, varnish and oxides
before using ethanol fuels. If you don’t ethanol fuels
will do it for you and clog filters and cause fuel pump
and/or engine failure.
Ethanol fuel users
storing fuel more than 60 days should use a premium fuel
stabilizer such as “GAS-SHOK”™
or expect to have the tank and fuel cleaned annually.
(Boats, RV’s, emergency generators, Etc) Ethanol
fuels will absorb significant water right out of the air
if stored 60 days or longer.
Ethanol fuel filtration facts & secrets:
Fuels are typically stored in many tanks at different
locations and can take 30 to 90 days to get from a
refinery to you. If any of those tanks have water or
other contamination (and most do) some of it will likely
make its way into your tank.
help combat the growing problem most engine producers
currently require owners to use finer 10-micron filters
or risk a voided warranty. As a further safeguard some
engines are fitted with a second 2-micron filter on the
engine itself. (Yamaha, Cummins)
Fuel Service has pioneered the most effective method
available to restore fuel quality and engine
reliability. We purify fuels by adding a blend of
proprietary tank cleaning additives and circulating the
fuel through high volume fuel filtering machines that we
built in-house. Most fuel polishing companies just
filter your fuel or pump the tank dry and you lose your
expensive fuel. Our process typically saves 85-90% of
your fuel while cleaning the tank and filtering your
fuel. In most cases our cleaning process can eliminate
expensive fuel loss and disposal fees by rejuvenating
your fuel to refinery fresh quality for safe use. Our
process will not harm engines or components or affect
warranties. We have many years of experience and a
proven track record and testimonials that confirm our

ISSUES AND SOLUTIONS FOR ETHANOL FUEL USERS
Ethanol blended E-10/85 fuels has several
unique characteristics not found in previous fuels.
Fact 1: E-10/85 Ethanol blended fuels
are powerful solvents that:
1. Strip away built-up gums and
varnish in fuel systems and tanks.
2. The result is particles of debris
that can clog filters and fuel systems.
a. The abrasive action of the
particles causes premature wear of expensive injectors
and fuel pumps.
Add “GAS-SHOK” ™ industrial strength fuel
additive to break down and dissolve those particles so
there is no clogging or abrasiveness, it then safely
burns during the combustion process and provides full
power and fuel performance.
FACT 2: E-10/85 Ethanol blended fuels
are very unstable and begin to break down in a very
short period (30-90 days).
1. The ethanol and other fuel
components can begin to evaporate and degrades resulting
in stale fuel.
2. The symptoms are hard starts,
hesitation, stalling, pinging, lose of power and can
lead to engine damage.
Adding “GAS-SHOK”™ fuel additive will
stabilize and ethanol fuels for 12-18 months and enables
the fuel to deliver full power and performance. It will
actually restore some old fuels and dramatically
improves engine performance.
FACT 3: E10/85 Ethanol fuels will absorb
accumulated condensation from fuel tanks and actually
attracts moisture/ humidity out of the atmosphere.
1. The water/ethanol solution is
suspended in the fuel until it reaches saturation.
2. It then turns into a milky slime
referred to as phase separation and accumulates in the
3. Ethanol represents several points
of the fuels octane rating therefore after phase
separation occurs the fuel has significantly lower
octane and is not capable of delivering full power.
4. The result is hard start, rough idle
or stalling and can eventually lead to engine damage.
Add “GAS-SHOK”™ fuel additive, the
formula contains state-of-the-art ingredients that
safely absorbs water. Combining “GAS-SHOK”™ with
ethanol fuels will prevent phase separation. We also
add powerful lubricants so suspended water safely passes
through the fuel system.
The heat generated during engine
combustion separates the water back out of the fuel as
steam. The steam boosts power, cleans engine valves and
combustion chambers which prevents carbon buildup.
**This results in a clean and water-free tank
and fuel system.
With “GAS-SHOK”™ engines produce more
power and run smoother.
There are no negative effects and engine
warranties are not affected!
Our unique proprietary formula also adds
combustion enhancers so regular grade fuel is boosted to
perform like premium grade. The savings more than pay
for the cost of our additive.
FACT 4: Ethanol blended fuels actually
produce less BTU’s of energy.
1. Lower energy means less fuel
2. Less economy leads to higher costs
per mile driven.
Add “GAS-SHOK”™ fuel additive with
advanced combustion enhancers that restores the fuel
economy. Compared to untreated fuel, “GAS-SHOK”™ will
produce a minimum gain of 10% in fuel economy.
This more than pays for the cost of using
In tests, we
found we could blend “GAS-SHOK” with regular fuel and
safely run it in most engines requiring premium fuel.
There was no pinging, knocking or power loss. The
engines are still running perfectly after using it for
more than three years.
