PRI-D is a super concentrate—one gallon treats 2000 gallons, and is
a complete fuel treatment that improves all diesel fuels enabling them
to perform to maximum potential.
PRI-D will stabilize biodiesel from B-5 to B-20. PRI-D's industrial
strength, enhanced thermal stability chemistry reacts with fuel upon
contact, and provides multiple benefits:
- Engines perform better and last longer.
- Increased power and fuel economy.
- Fuel stays fresher longer.
- Tanks and fuel lines remain free of slime and sludge.
PRI-D For All Diesel Engines:
Today's diesel fuels can go bad fast. Your engine smokes more,
your fuel systems foul, power and performance taper off and sometimes
your engine just quits. Don't get caught dead in the water or stopped
on the roadside.
Independent laboratory tests confirm no other product is as effective
as PRI-D in preserving new fuel and restoring old fuel to refinery freshness.
That's because refinery-grade PRI-D is an industrial concentrate—much
stronger and more effective than "consumer" brands. In fact, public utilities,
hospitals and municipalities depend on the same PRI-D strength to keep
stand-by generators running when emergencies hit. If you want only the
very best protection for your boat, generator, or RV, settle for nothing less

Prevents Carbon Deposits:
Nothing wreaks more havoc on a diesel engine than abrasive hard carbon
deposits. PRI-D literally prevents hard deposits, dramatically reducing liner,
piston, ring, valve and turbocharger wear. Just ask the chief engineers aboard
the ships we service or the maintenance managers of our onshore fleets. Take
a look at our piston comparison photos. PRI-D's enhanced thermal stability
chemistry will keep your engine running longer and farther than you ever
Stops Soot Build-Up:
Soot blackening your beautiful transom or new RV Proud boat and RV
owners love PRI-D for keeping things shipshape. That's because PRI-D
reduces diesel smoke up to 60 percent—the root cause of the problem. Your
equipment will look better, you'll breathe easier, and have more time for the
things you love doing.
Eliminates Tank Slime & Sludge From Algae:
Tired of constantly changing those expensive spin-on filters because of
algae slime While biocides like our own PRI-OCIDE are effective in killing
algae, they don't eliminate the slime produced by decomposing micro-organisms.
In fact, algae slime sinks to the bottom of your tank, building up a layer of muck
that can choke filters and leave you stopped dead when you hit rough seas or
It is important to note that biocides are not fuel stabilizers. They do nothing to
preserve fuel stability. Hence, it is recommended as part of a good fuel storage
practice to use a combination of an EPA-registered biocide and EPA-registered
fuel stabilizer. PRI-D and PRI-OCIDE are designed to work together to provide
maximum fuel reliability.
Only PRI-D dissolves the nasty slime and sludge that results from algae infestation.
PRI-D also preserves your fuel to maximum freshness—actually eliminating the
conditions that cause algae growth. Eliminate expensive fuel polishing and tank
cleanings. Don't let your tank be a bacteria graveyard.
Improved Engine Performance:
PRI-D works chemically within diesel fuel to improve the combustion
process. Improved combustion means improved engine performance.
You will realize increased power from your engine. At the same time,
you will enjoy greater fuel economy. PRI-D is also extremely effective
at reducing harmful emissions, including smoke opacity, NOx, and SOx.
Reduced Maintenance Costs:
PRI-D is a highly effective preventative maintenance tool. PRI-D’s proprietary,
refinery-grade chemistry is unsurpassed at preventing carbon deposits and fuel
system fouling. Your engine will remain cleaner and last longer. In addition, the
tank slime and sludge that diesel fuel users commonly encounter is eliminated.
Extended Storage Life:
Properly treated with PRI-D, your diesel fuel will stay fresh in storage for months
and even years at a time. Tests have shown where PRI-D has gone a step farther,
actually restoring old fuel to refinery-fresh conditions.
PRI-D is super concentrated, treating fuel at a 1:2,000 ratio. This means PRI-D
is extremely cost effective to use. Get the most out of your diesel fuel for only
pennies a gallon.
Safe To Use:
PRI-D’s enhanced thermal stability chemistry works within the fuel instead
of altering it, which means the product is completely safe to use. PRI-D contains
no potentially damaging Cetane improvement additives or harsh solvent
chemistries. No fuel specifications are changed, therefore PRI-D meets all
major engine manufacturer fuel specifications—warranties are not voided.
This product has been used by industrial fuel customers for years, although
not widely known in the consumer market, it is the best fuel treatment available.
One of the greatest assets of PRI Fuel Treatments is the long term fuel
storage and the ability to recover old stored fuels. If you have used
Power Service or Lucas you will find that PRI is a far superior product and
less costly per gallon to use.
Our industrial clients simply cannot afford fuel failures. They depend on
PRI for complete system integrity and reliability. Among the units now
relying on PRI-D are operators of standby generators at conventional and
nuclear power plants, major ISPs like America Online, telephone companies,
hospitals, and vital emergency services.
Extends Diesel Fuel Storage Life:
Properly treated with PRI-D, your diesel fuel will stay fresh in storage for
months and even years at a time. You’ll be assured a fast start next season
simply by treating your fuel with PRI-D prior to storage. PRI-D goes a
step farther, actually restoring old fuel to refinery-fresh conditions. If you
are storing diesel fuel for any period of time, you can’t afford to be without
Since fuel is an organic material, it begins to age and deteriorate the minute
it leaves the refinery. By the time you put "fresh" fuel in your tank, it has
already aged considerably. Fuel continues to age as it sits in your tank, but
worse yet, this aging process is accelerated during combustion.
During the aging process, masses of carbon, gum, and resin form. These masses
become too large to burn completely, and the combustion process is compromised.
As a result of this aging process and incomplete combustion, your engine does
not perform as designed. Fuel burns less efficiently. Energy and power are lost.
Fuel efficiency is reduced. The unburned matter forms abrasive, damaging
deposits in your engine and fuel system.
Fuels age because they become "chemically unstable." During transportation,
storage and use, fuels are exposed to oxygen and heat. This exposure causes the
atoms in the fuel to lose their balance (i.e. become unstable), molecular reactions
take place, and the aging process begins. This happens to all fuels, even today's
reformulated "clean" fuels.
This aging process can be halted and even reversed. If the fuel is kept in
balance—kept "chemically stable"—then aging does not occur. This is exactly
what PRI Fuel Treatments do. This is why PRI Fuel Treatments are referred to
as "fuel stabilizers.”
PRI-D is super concentrated, treating fuel at a 1:2,000 ratio. This means
PRI-D is extremely cost effective to use. Get the most out of your diesel fuel
