41.3 oz bottle treats up to 275 gallons of fuel.

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

Power Boost: 3 oz of AR6300 per 10 gallons (reduces CFPP to -44ºF)

For warmer seasons, when no anti-gel protection is needed, use AR6500 Diesel Treatment instead.

AR6300 is suitable for use in all diesel vehicles, including newer systems such as High Pressure Common Rail.

Unlike other cold weather treatments, Archoil’s AR6300 Winter Diesel Treatment not only provides anti-gel protection, it also enhances lubricity, increases cetane, and continuously cleans injectors, turbos and DPFs. This is the ONLY fuel additive you need to ensure your diesel powers through the cold weather.

AR6300 utilizes proprietary chemistry found in AR6500 Diesel Treatment. That means you get all the benefits of our best-selling premium diesel additive PLUS anti-gel protection every time you fill up. Protect your engine and maximize performance right through the winter.

Anti-Gel Protection You Can Rely On

When temperatures drop below freezing (32°F), the wax in diesel fuel starts to crystallize, clogging your fuel filter. This process is known as gelling and leads to a number of problems, including: 

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

AR6300’s provides powerful anti-gel protection, preventing fuel from gelling down to temperatures as low as -44ºF (using Power Boost treat rate). By safeguarding against gelling, AR6300 ensures your diesel engine runs smoothly and efficiently on the coldest days.

Enhance Lubricity to Prevent Wear
  • Protect against sub-zero temperatures
  • Improve cold-weather engine reliability
  • Extend component lifespan

Insufficient lubrication in diesel fuel is a major concern for vehicles all year round, but especially in winter. Cold weather thickens fuel and increases friction between components, leading to increased wear on your engine and fuel system.

AR6300 provides a stronger lubricity boost than other treatments and has been independently tested to reduce wear by 43%, protecting engine components and extending their lifespan.

Maximize Performance & MPG
  • Improve cold-weather combustion efficiency
  • Enhance fuel economy
  • Increase winter power and performance

Diesel engines typically perform best with a cetane number (CN) of 48-50, but regulation in most of the US only requires a CN of 40. Using fuel with a lower CN leads to poor combustion, especially in cold weather, where efficient ignition is crucial.

AR6300 increases the CN of your fuel by up to 8 points, significantly higher than other diesel products on the market.

The Only Winter Treatment That Cleans the Entire Fuel System

Clean Injectors and Protect Your Engine
  • Improve fuel atomization in cold weather
  • Reduce build-up of harmful carbon deposits
  • Enhance fuel economy

Over time, carbon deposits build up on diesel injectors, leading to poor fuel spray patterns. Dirty injectors can't atomize fuel correctly, resulting in incomplete combustion - a problem that only worsens in cold weather.

AR6300 keeps injectors clean, even in the coldest conditions, allowing your injectors to deliver fuel to the engine as intended.

Prevent Turbo Lag & Failure
  • Improve cold weather throttle response
  • Reduce wear and damage
  • Maximize air intake for improved performance

A dirty turbo leads to restricted airflow, reducing engine efficiency, increasing fuel consumption, and causing turbo lag. Carbon deposits can also lead to overheating and potential turbo failure. 

AR6300’s proprietary chemistry survives combustion and uses exhaust heat to remove carbon build-up from the turbo, restoring boost and reducing lag.

Clean Your DPF & Reduce Regens
  • Reduce regens, even in cold weather
  • Restore MPG and boost performance
  • Prevent damage and increase DPF lifespan

Carbon build-up in the diesel particulate filter (DPF) can drastically reduce engine performance and increase the frequency of regens. This problem only gets worse when temperatures drop below freezing.

AR6300 is the only winter diesel treatment that cleans your DPF. Its proprietary chemistry effectively removes carbon and soot build-up to restore performance and reduce regens.

AR6300 FAQs

AR6300 is suitable for all diesel vehicles, including newer systems such as High Pressure Common Rail.

AR6300 will remain stable indefinitely if kept away from sources of heat and sunlight.

To maximize diesel power and performance we recommend that you use AR6400-D Diesel Fuel System Cleaner to provide a deep clean to your fuel system every 5,000 miles.

You can then use AR6300 Winter Diesel Treatment (or AR6500 Diesel Treatment in the warmer months) at every fill-up between uses of AR6400-D.

Both AR6300 and AR6500 boost cetane, improve fuel lubricity, and contain a maintenance dose of detergents to maximize fuel system performance at every fill-up.
