Get the most out of your dieselWinter Diesel Kit
For best results, use AR6400-D Diesel Fuel System Cleaner first to remove heavy deposits and restore power, performance and MPG. Follow up with AR6300 at every winter fill-up onwards.
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. 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
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.

I was skeptical at first, tried some of the other products, but didn’t produce tangible results. My 2022 6.7 dually runs quieter, noticeably! The mpg has gone up 3-4 mpg both towing and highway runs. There are less regens. The big difference is it uses less def. I am totally convinced that there is a difference. AND, when you call for tech support or a question, a real live English speaking person answers the phone! Thats impressive.

Great product. I use it in my 3.0 diesel. My truck is parked for days when I go snowmobiling.. I don't have the luxury of plugging the heater in and I have peace of mind knowing my fuel won't gel at even -30F
A
I can definitely tell the difference when I started using. Engine is running much more smoother.
D
I get the AR6300 not because it’s cold where I live. I get it because I could go where it is cold and don’t want to worry about fuel gelling and hard starts. I’ve used Archoil products from day one when I bought my truck and plan to use it over the life of my truck.
D
Works wonders for regens and fuel boost
C
Tried my first bottle of AR6300 works amazing compared to many other arrivals on the market and when it warms up in temps I’ll be giving it a dose of the DPF cleaner to blow out the nasty soot that clogs our DPF filters giving my truck the robust beast that it is taking this 2021 GMC Sierra Duramax LM2 back to the showroom condition it deserves!!! Thanks Archoil for Elite products !!!
R
It works great the diesel gauge doesn’t move like it did before less fill up
D
The temps dropped to below zero this weekend and the truck is running great, have seen an improvement in the mileage as well.
J
Only been using this product for about a month. So far so good. Never really hurts to add a little extra protection. If the united states would produce diesel the way it is supposed too we wouldn't need additives.

I am new to the diesel world. Got myself a 2022 F250 6.7 crew cab long box. It’s like driving a bus without annoying kids screaming all the time, just some of the time when my kids are in there LOL! Needless to say I had to do my research on what was best to keep my fuel system running as good as it can. I live in upstate NY today’s temperature was 8 degrees. I had two concerns that my truck went into regen way too often, and I use my truck for my landscaping/snow removal business, so getting better GPM numbers, especially on load with a trailer or my salter with a ton and a half of salt. It fixed the regen for sure, this is my second bottle of the AR6300. I’d say I went into regen at least 2 or three times a day. I do a lot of little trips so I don’t get to burn the DEF out. It now maybe does it once a day, maybe every other day. I’ve also gained 9% more in the GPM, even with a full dump trailer with skid steer and the salter in the back of the truck full.
I have told so many people about this! I’m so happy when a product works as it says it does. You don’t always see that these days!!! Thank you for this product, I have a bottle of the system cleaner that’s going in tomorrow. I may even change my oil changes to their oil!
M
Used half a bottle in my fuel tank. Not enough yet for results!! Only drive this pickup 5000 miles a year, sorry no info as of yet!

I have been using archoil winter treatment for 40 days. What a great product. I use it in both of my Chevrolet diesel trucks with awesome results. We have been averaging around 20 degrees, performance seems to have increased. Love the product. Thank you
J
I could tell a difference within 10 miles of using it the first time
👉🏽Engine sounded smoother
👉🏽Throttle response is quicker
👉🏽Full milage improved to 20+mpg
I’ve been using it for about a year now, and will purchase again
Thank you
M
Use this in alaska most of the winter. Awesome product and no issues.
J
I have ran HotShots almost every single tank for the past 3 years and 380k miles until this last trip. 5k miles and a bottle of this and i noticed my mileage, pulling a 40ft livestock trailer as i do 99% of the time, went up almost 2 MPG. Think i found a new additive!!
B
I’ve been using Archoil for the fuel and the oil for a little over 4 years now, ever since my 6.0 was rebuilt by Powerstroke Specialties in Buford, Ga.
Bill Hewitt recommended it and I completely agree.
K
-5 degrees in Wisconsin, forgot to plug truck in, went outside and fired right up. I’d say it does it’s job!
B
Ever since I’ve owned my 7.3 I’ve been using the stiction modifier in every oil change as well as the fuel additive every fill up. Very happy how my truck is running. Currently using the winter fuel additive up here in MN. No gumb up or freezing fuel issues and starts well in the two -15 days we’ve had so far. Will never stop using these products.
J
I have used Archoil products since I bought my ‘05 F350 6.0L 5 years ago. I had a stiction issue which was resolved by AR6400 & AR9100 (oil additive). When winter came & freezing temperatures I needed an anti-gel product. AR6300 was my only option since I had great results with the other two products. Never had a problem with cold starts. The truck runs great! I highly recommend all Archoil products for diesel vehicle owners.
J
Funkiest bottle I've ever seen. But, every Archoil product I have ever used has worked incredibly well. Use anything you make for the Ford 6.0 Powerstroke. If you get around to making a transmission additive, let me know. I'll be the first one to buy it.
J
I love this product helps my truck run great and I use it in all my diesels all the time
T
Use the AR6500 and love it got this to prepare for winter. Excellent products
G
I use the standard Archoil AR6500 on my 2024 Chevy 3500 Duramax since new, runs great and getting up to 11 MPG pulling my 5th wheel camper. I use this when winter comes since the truck is in an unheated garage and I live in the northeast. Same great stuff but keeps the diesel from gelling. I will start adding this around November.
J
Product is great. I used it in my 6.0 and continue to use it in my 6.7. I use the Archoil products in all my vehicles. Only issues I've had is with shipping. Every time my order is lost, damaged, or delayed. Customer service always handles arrordinly but please use someone other than the USPS.
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.
