What Happens to Fuel When it is Stored?
Any fuel, be it gasoline, diesel, or heating
fuel, is made up of many different organic compounds. These organic
compounds are constantly changing over time becoming new compounds
that change the characteristics of fuel. The same molecules that
make up the best parts of gasoline can react with oxygen and other
elements in the environment and form new molecules that build
up to form gummy residues or varnish-like films that can clog
up passages in fuel lines, carburetors, and injectors.
Some fuels are treated with oxidation inhibitors to allow them
to be stored for up to 3 months without generating excessive deposits.
Other fuels have no inhibitors at all. In any case, storage of
equipment requires some special consideration for the fuel system.
Why Can't These Problems be Avoided by
One way to avoid most of these deposits
is to completely drain the fuel tank and fuel lines. This procedure
poses a number of problems. First, it is virtually impossible
to get every drop of fuel out of the system by simply draining.
In order to remove all fuel, lines must be blown out and dried,
or enough fuel will remain to cause problems. Second, draining
the fuel exposes the bare metal in the tank and fuel system to
air and moisture which, together, can result in the formation
of rust and corrosion and which can allow gaskets to dry out,
crack and shrink, leading to fuel leaks when the system is refilled.
Third, drained fuel is a fire and safety hazard and represents
an environmental problem. Properly disposing of this fuel is difficult.
For these reasons, draining is not the solution.
Does Fuel Stored in a Tank or Can Cause
Fuel stored in cans or tanks will also
oxidize with many of the "bad acting" unstable molecules
remaining in the solution. Using this fuel next season, greatly
increases the likelihood that deposits will form in fuel systems
while the equipment is used. In other words, stored fuel needs
What Does PRI-D & G Do?
PRI-D & G are a blend of scientific
additives all of which act together to prevent fuel from undergoing
degradation and oxidation during prolonged storage.PRI acts as
a protective wrapper around fuel molecules so they cannot combine
with oxygen or other molecules to form new "bad actor"
molecules. The "sweetened" fuel will perform its job
thereafter as though it had just been freshly pumped into the
fuel tank straight from the refinery pipeline.
How Well Does PRI-D & G Work?
Better than you can imagine. On average,PRI
improves gasoline life 5 times. The average gasoline is extended
from 3 months oxidation life without PRI to 15 months withPRI.
Compared to any other products pretending to extend fuel life,PRI
is 4 to 9 times more effective according to accepted standard
fuel stability tests IASTM D5251.
What Kind of Engines Need PRI?
Any engine stored for 90 days or more needs
PRI. This includes all 2-cycle or 4-cycle engines used in lawnmowers,
marine engines (inboard and outboard, snow-throwers, motorcycles,
chain saws, recreation vehicles, snowmobiles, generators, pumps,
golf carts, automobiles, trucks, garden tillers, lawn edgers,
garden tractors, farm equipment, mini- bikes, motorscooters, you
name it. If it has an engine and is stored for a season or more,
it needs PRI.
Is PRI Hard to Use?
It's simple. Just add PRI to the fuel according
to the recommended dosage on the package. (Measuring is easy based
on the number of squeezes through the measuring cap. Agitate
the fuel tank if possible, then start and run the engine for 5
minutes or more. After that, simply shut off the engine and store
the equipment away. Next season, the engine will start easily
and run smoothly.
