PRI-G Gasoline Treatment

For E-10 and All Gasoline Grades

PRI-G is a concentrated gasoline treatment designed for gasoline storage, generators, vehicles, boats, RVs, small engines, and other gasoline-powered equipment.

Why Use PRI-G?

• Keeps gasoline fresh during storage
• Helps restore degraded gasoline
• Helps inhibit phase separation in ethanol/E-10 fuels
• Helps prevent fuel-system deposits and carbon buildup
• Improves combustion and engine performance
• Reduces hesitation, knocking, and pinging
• Contains no alcohol
• Safe for four-stroke and two-stroke engines

Ideal for Emergency Fuel Storage

Gasoline begins to deteriorate after it leaves the refinery, and heat can accelerate that process. PRI-G is formulated to slow fuel degradation and can also help restore gasoline that has already aged.

This makes it particularly useful for emergency generators and stored backup fuel, where dependable starting after long periods of storage is important.

Highly Concentrated

Treatment ratio: 1:2,000

A small amount treats a large quantity of gasoline, making PRI-G economical for both everyday equipment and long-term fuel storage.

Shelf life after opening: 3 years

PRI-D Diesel Treatment

Industrial-Grade Treatment for Diesel Fuel & ULSD

PRI-D is a concentrated diesel fuel treatment designed to improve fuel stability, lubricity, combustion, and overall fuel-system performance.

It can be used with diesel fuels including ultra-low sulfur diesel (ULSD).

Why Use PRI-D?

• Keeps stored diesel fuel fresh
• Helps restore degraded diesel fuel
• Helps inhibit algae growth
• Provides additional lubricity for ULSD
• Helps protect fuel pumps, O-rings and seals
• Helps keep fuel injectors clean
• Helps remove fuel-system slime and sludge
• Reduces carbon buildup
• Helps reduce smoke and soot
• Improves combustion and engine performance

Fuel Stability & Storage

PRI-D is designed to help prevent degradation during long-term diesel storage and can help restore fuel that has already degraded.

Its stability performance has been evaluated using ASTM accelerated fuel-stability testing.

Lubricity Protection

PRI-D includes a lubricity additive package intended to provide additional protection when using ultra-low sulfur diesel. This can help reduce fuel-pump wear while protecting important fuel-system components.

Highly Concentrated

Treatment ratio: 1:2,000

PRI-D’s concentrated formula allows a relatively small quantity of treatment to condition a large volume of diesel fuel.

Shelf life after opening: 3 years

How PRI-G Stabilizes Fuel:

The minute gasoline exits the pipeline from the refinery, it begins to age and deteriorate. Depending on a variety of factors, the extent to which gasoline degrades is highly variable.

A key factor affecting gasoline stability is heat. When gas tanks are continually exposed to warmer temperatures, gasoline degradation accelerates.

Fact is, gasoline can go bad in as little as a few weeks in hot summer months. The results can be devastating for engines and fuel systems, resulting in:

• Start-up Failures
• Fuel system and filter fouling and damage
• Gum and varnish accumulation in tanks
• Excessive carbon deposits on engine components
• Engine damage

PRI’s research staff has developed a series of very powerful stability chemistries that are incorporated into PRI-G to prevent fuel degradation for all gasoline blends, including E-10 blends with ethanol.

Additionally, PRI-G is formulated to reverse the effects of severe degradation, restoring degraded gasoline to a useable condition.

These capabilities have been proven, time and time again, in standard ASTM 525 laboratory testing for oxidation stability. In these tests, the gasoline is heated to 212° F. in a pressurized chamber with an atmosphere of pure oxygen.

When the pressure drops, this means that the gasoline has absorbed oxygen and oxidized. The time it takes to oxidize the gasoline is recorded. Each minute that goes by without the pressure drop represents one day of fuel life. Hence, with the minimum industry standard of 240 minutes – gasoline can be expected to remain stable for 240 days under normal storage conditions.

Yet PRI-G treated gasoline extends the test time to more than 12 hours – extending freshness to two years and more!

How PRI-D Stabilizes Fuel:

The minute diesel fuel exits the pipeline from the refinery, it begins to age and deteriorate. Depending on a variety of factors, the extent to which a diesel degrades is highly variable.

In recent years more and more refineries are adding nitrate-based cetane improvement additives, now proven to accelerate degradation. Many diesel fuel streams are also blended with small amounts of light cycle oil (LCO), which also contributes to degradation. The result? Degraded fuel with poor ignition quality and a tendency to foul fuel systems and engines with damaging carbon deposits.

PRI’s research staff has developed a series of very powerful stability chemistries that are incorporated into PRI-D to prevent fuel degradation for all diesel fuels.

Additionally, PRI-D is formulated to reverse the effects of severe degradation.

These capabilities have been proven, time and time again, in standard ASTM laboratory testing for accelerated stability. In these tests, fuel is heated and oxygenated for 16 hours, then filtered. Residue produced by instability is filtered and weighed in terms of milligrams per 100 milliliters. Below are results of some of the many hundreds of tests conducted on PRI-D over the years.
