MAXIMUM DIESEL POWER & ANTI-GEL PROTECTION

HIGH PERFORMANCE
IN LOW TEMPERATURES

Anti-gel protection

When temperatures reach freezing point (32°F), the wax in diesel fuel begins to crystallize and collect on the fuel filter. This prevents fuel from getting to where it needs to be, leading to:

  • Trouble starting the engine
  • Poor acceleration
  • Sluggish and noisy performance

The anti-gel properties of AR6300 can prevent diesel fuel gelling down to -44ºF (using the Power Boost treat rate). Preventing gelling ensures your fuel system keeps working efficiently through the colder months.

The ONLY treatment your diesel needs in cold weather

Most cold weather diesel additives only offer anti-gel protection. AR6300 Winter Diesel Treatment increases lubricity, boosts performance, restores fuel economy and cleans the fuel system to ensure your diesel powers through the winter. Your vehicle gets all the benefits of AR6500 Diesel Treatment PLUS anti-gel protection at every fill-up.

AR6300's highly concentrated formula contains no fillers and utilizes Archoil's proprietary fluid technology to remove carbon build-up from the turbo, DPF and EGR. AR6300 delivers a complete clean and boost package to the entire fuel system to protect your engine and maximize performance.

Protect High Pressure Diesel Fuel Systems

The ASTM D-975 Diesel fuel specification requires diesel fuel sold in the USA to produce a wear scar diameter no larger than 520 microns, while the Engine Manufacturers Association recommends diesel fuel to produce a wear scar diameter of no larger than 460 microns.

This means fuel that meets ASTM D-975 may not be lubricious enough to meet the Engine Manufacturers Association's recommendation, and therefore may not provide adequate protection to modern high pressure diesel fuel systems.

AR6300 will help protect high pressure diesel fuel systems from failure due to inadequate lubricity.

How it Works

Helps prevent diesel fuel from gelling

At low temperatures diesel fuel gels and can plug your fuel filter and prevent fuel from flowing to the engine. AR6300 lowers the cold filter plugging point of diesel fuel which helps ensure fuel flows when you need it to.

More complete fuel burn

AR6300 will ensure correct injector spray patterns and a more complete fuel burn which improves fuel efficiency, power and response. A more complete fuel burn also means less soot/carbon emissions are produced which keeps the engine, turbo, and emissions systems (EGR, DPF etc.) free from soot deposits.

Keeps Diesel Particulate Filter clean

Due to reduced soot emissions, vehicles equipped with a Diesel Particulate Filter (DPF) will benefit from reduced frequency and length of DPF regeneration, which results in big fuel efficiency gains. When the DPF captures less soot, much less fuel is needed to burn it off, and there is less exhaust backpressure which reduces engine efficiency.

Protects fuel system

Detergents will keep your fuel system clean preventing the formation of power/economy robbing deposits and a lubricity improver will prevent wear in all fuel systems including the most modern high pressure fuel systems. AR6300 will also combat corrosion as well as disperse water and keep fuel filters clean.

Stabilizes fuel

AR6300 will maintain fuel stability by preventing fuel from degrading and forming sludge and varnish which does not burn readily and can plug fuel filters and injectors if left untreated. A powerful dispersant will dissolve sludge and varnish allowing it to pass through your fuel system and burn completely.

Treat Rate

A 41.3oz bottle treats up to 275 gallons of diesel.

At low temperatures diesel fuel gels and can plug your fuel filter and prevent fuel from folowing to the engine. AR6300 Winter Diesel Treatment lowers the cold filter plugging point of diesel which helps ensure fuel flows when you need it to.

Lubricity in fuel at the gas station is unlikely to meet the level your vehicle requires as EPA regulations don't meet the standards of the Engine Manufacturers' Association.

AR6300 improves lubricity and protects your engine against excessive wear and premature failure, reducing the potential for costly repairs. This is particularly important as diesel engines are more likely to suffer damage in cold weather.

AR6300 brings all the same benefits to your vehicle performance as AR6500 Diesel Treatment plus anti-gel protection.

AR6300 boosts cetane to improve combustion, keeps key fuel system components clean and protects against corrosion which leads to improvements in fuel economy (MPG).

41.3 oz bottle treats 275 gallons of fuel.

Standard: 1.5 oz of AR6300 per 10 gallons of diesel (reduces CFPP to -16ºF)

Power Boost: 3 oz per 10 gallons (reduces CFPP to -44ºF)

When no anti-gel protection is needed, use AR6500 Diesel Treatment.

Enhance Lubricity

AR6300 improves the lubricity of diesel fuel which is particularly important in cold weather as winter fuel contains less lubricity and diesel engines are put through more wear and tear when temperatures drop.

A lack of lubricity in fuel can lead to:

  • Excessive wear
  • Premature failure
  • Costly repairs

The Engine Manufacturer's Association (EMA) recommends using fuel that produces a wear scar no larger than 460 microns to meet the needs of a vehicle. The diesel fuel specification in the United States (D-975) is only 520 microns, meaning additional lubricity must be added to meet the EMA recommendation - highlighting the importance of diesel fuel additives.

In wear scar testing (ASTM D6079), base diesel fuel produced an out-of-spec scar width of 614.5 microns. The same fuel treated with AR6500 produced a scar width of 347.5 microns - a 43% increase in lubricity. Improving lubricity extends component life and prevents premature failure.

Maximize Fuel System Performance

As well as providing anti-gel protection and enhanced lubricity, AR6300 brings all the benefits of Archoil's all-in-one AR6500 Diesel Treatment. AR6300 boosts cetane, improves fuel efficiency and cleans the entire fuel system

If you haven't been using diesel treatments regularly, we recommend using our highly-concentrated AR6400-D Diesel Fuel System Cleaner before using AR6300. AR6400-D is a one-tank treatment which rapidly removes heavy build-up and deposits from the fuel system.

RESTORE INJECTORS

• AR6300 removes internal diesel injector deposits (IDIDs) and carbon build-up from injector tips

• AR6300 ensures correct injector spray patterns, resulting in a more complete combustion and lower emissions for optimized performance

BOOST TURBO PERFORMANCE

• AR6300 clears the turbine and variable vanes of soot and carbon, reducing turbo lag and restoring boost

• AR6300 prevents the accumulation of carbon to reduce excess heat and wear, avoiding premature failure of the turbo

REDUCE DPF REGENS

• AR6300 improves combustion to reduce carbon, soot and particulate exhaust emissions

• AR6300 removes soot and heavy carbon deposits from the DPF which reduces regen frequency, restores lost performance and prevents engine damage from a clogged DPF
