Clean, restore and boost the entire fuel system
AR6500 upgrades the quality of diesel fuel at every fill-up by providing a strong cetane boost, enhanced lubricity and a powerful detergent package.
AR6500 maintains clean injectors, and unlike other diesel additives, keeps your turbo and DPF free from carbon build-up.
Add at every fill-up to:
- Improve combustion efficiency
- Increase fuel economy
- Reduce DPF regeneration
- Protect the fuel system
- Extend component life
Boost cetane to increase power and response
Most diesel engines require fuel with a cetane number (CN) of 48-50 to operate efficiently but fuel in the US typically has a CN of 40-45. A low CN results in poor combustion, causing soot deposits and carbon build-up in key fuel system components.
AR6500's cetane boost of up to 8 points is greater than other products on the market, helping to:
- Improve combustion efficiency
- Enhance fuel economy
- Increase power and performance
- Extend component life
Improve lubricity to extend fuel system life
Lack of lubrication in diesel fuel is a major issue for both older and newer vehicles, leading to excessive wear, costly repairs and potential failure of components including injectors and pumps.
AR6500 has been independently tested to reduce wear by 43%, reducing friction and wear on the fuel system in order to:
- Protect engine components
- Reduce maintenance costs
- Improve engine reliability
- Extend component lifespan
Clean injectors and restore spray patterns
Over time, carbon deposits form on diesel injectors. Dirty injectors can’t spray fuel into the engine correctly, leading to incomplete combustion and wasted fuel.
AR6500 not only keeps injectors clean but by increasing cetane and improving combustion, helps prevent further build-up of deposits.
- Improve fuel atomization
- Reduce carbon deposits
- Enhance fuel economy
Keeps the DPF clean and reduces regen frequency
Carbon build-up in the Diesel Particulate Filter (DPF) reduces engine performance, lowers fuel economy, and leads to increased regeneration frequency.
AR6500's proprietary chemistry cleans the system and will:
- Reduce regeneration frequency
- Restore MPG & performance
- Prevent DPF-related engine damage
- Increase DPF lifespan
Prevent turbo failure and restore boost
A dirty turbo restricts airflow, leading to reduced engine efficiency, increased fuel consumption, and turbo lag. Carbon deposits can also cause overheating and potential failure, resulting in costly repairs.
By cleaning the system, AR6500 will:
- Reduce turbo lag
- Restore boost
- Minimize wear and damage
- Restore optimal temperature
- Improve airflow efficiency

I saw and heard a difference the first time I used AR 9100 oil additive, smoother running and cold starts are better also, I've been using this for over a year now and it's definitely shown positive results in both my 7.3 trucks.
R
My service truck is a 2000 f350 and I put a ton of miles on it every month but it does alot of idle time also. After using it for a few days I noticed better fuel mileage and it's running a little but quieter thanks again I'll definitely be ordering once a months since I put 2500 or more miles on this truck a month.

2000 excursion with 7.3 just purchased so I don't have the history. Looks like it's got mostly original parts. Only on my first oil change but have put a couple thousand miles on and looks like I've picked up from 11 to 13 mpg towing . And had it in 25 below zero Montana cold snap. Of course plugged in, but started pretty good. Seems to be getting better and better all way around. I'll use the cleaner next and continue with treatment. No brainer that fuel savings more than pays for itself.

I’ve been using Archoil for about a year now, maybe a bit more
I just completed a 650 mile round trip in a 2016 RAM 2500 (one owner) and got 22.52 mpg running 75mph on cruise
(Kingston, Okla to Anderson, Tx and back)
Enough said

With 270,000 miles on my F350 6.7 diesel it still runs better than new.

I thought I was gonna have to replace my injectors due to Stiction. A buddy of mine suggested using Archoil before I replace them. I gave it a shot and my truck has never ran smoother. Definently worth the money for all you 6.0 guys out there.
C
As most additives you throw in you do it with a prayer and hopes of a miracle! I threw it into my 6.0 and after the first miracle of my truck firing right up I proceeded to take more of a risk and run her for over 2 hours on the highway. Now I’d been having slightly rough start ups/idling and a lot of hazing. I kid you not the next morning she fired up idled beautifully and almost no haze. Fast forward a couple weeks no haze on start up or idle. The rough starting/idling is gone and she couldn’t be running any better. 100% using again!

I’ve used the friction modifier in my first oil change since owning my power stroke and the difference it’s made in 5000 miles is absolutely insane. Better starts, no more white smoke, better acceleration.
I always use the diesel treatment as well and my tuner showed 11.6 mpg before arch oil and now with running it 1oz per 10 gallon I’m averaging 15.8 with a delete and tune.

So I'm new to this product and just changed my oil and added the AR9100 to my truck.
I own a 03 2500HD with a 8.1 liter, I've tried other additives before and they did ok " Lucas ". I do lots of heavy towing and hauling gravel along with wood with this truck, and it works hard for me. So I'll do and update after 5,000 miles and again in 10,000. That way I can give you an honest opinion. Looking forward to seeing how works out
A
Works good I’d say it’s got 30 percent more power, kinda I like took 300k miles off.
J
Honestly I appreciate the opportunity to leave a review. I haven't noticed any improvement with the oil additive and the Diesel additive.
Not sure if it's worth that kind of money when doing oil changes. It's over 200$ with oil, additive and filter. But I haven't noticed any change in 1000 miles of driving my truck.

I observed this product on a promotion advertisement. Since, many similar product announcing how good they are, but at last they won't last as what they committed. At the meantime, I keep using fuel cleaner to have my car engine running quietly and of course a quality engine oil is must. This oil additive is new to me, I tried it only few week, my hybrid car engine getting great improvement of quietness and better acceleration response. Even during idling the car is so quiet as like a electrical car. Completely, you can't hear any noise from engine compartment. I will keep track of its performance and its lasting on coming oil change. Will you take drug or take supplement for your health maintenance. Fact is Fact, verbally is won't work for it. Try it yourself to get the Truth.

My 08 RAM 5.7 HEMI with 158000 miles has always run perfectly with the engine sounding like a BIG A$$ watch, quiet, smooth, and if it was not for the radiator fan, nearly silent-almost. With the cost of ANY replacement vehicle being ASTRONOMICALLY HIGH, this bad boy needs to keep running until the cows come home. Since adding 8 ounces of the AR9100 at my last 7 quart oil change, the engine is definitely more responsive to the pedal and the overall performance is not just the "normal" - driving better feeling that everyone experiences just after a fresh oil change. The quietness and power that is evident by using this product is NOT imagined, but, REAL. I did not have any "HEMI tick" sounds before using this product and with the protection afforded with the AR9100, I do not expect to have any engine problems in the future. P.S. My lawn tractor and inverter generator are both also benefiting from the exceptional "anti-friction" properties of the Archoil AR9100....

My 2015 , F-250 6.7 diesel has 200k Mile’s on it . This product continues to perform as claimed . No rough cold starts , added lubricant to the internal parts - For the cost and peace of mind this product- I wouldn’t run a diesel truck with out arch oil.
N
The best anti stiction additive out there hands down. I run it every oil change which is now once a year! Just now started to run the fuel additive and will continue to do so from now on! My Ol gal needs all the love she can get. 2004.5 / 264k
A
I've been using it for about 3 years now and from the first use, I've noticed and improved, smoother running engine. I also use the fuel additive, AR6500 and that too has made a big difference. I'm just an average guy and just know it works.
J
I just cannot believe how much better my old 2007 F350 runs with this product.
K
Fires right up, no smoke, no chugging. Works great!
j
Have used in 1999 dodge 1ton diesel and oil stays clean longer . Does not look like diesel oil . Maybe i have a really good motor .
J
The product really does the trick on my 2007 Ford F-350. It just turned 306,000 miles. Love Archoil

I’m a DIY person (unless you need special software that’s my preference) Not to get away from the importance of reviews both good or bad I am familiar with diesel 2-3 fuel additives of standyne but wasn’t familiar with Archoil at first. it was time to figure that out and if necessary add with the next oil change (shell t4 15w-40 oil & wix 51734) I stayed with conv oil after a personal experience that supported staying with conv for my 02. So when it came time to purchase an oil additive I almost went with a competitor. However the competitions reviews and other factors helped me decide on choosing Archoil AR9100 bought a 2 pack. It’s been a month now since the 1st 16oz was added with a fresh oil/filter Change and I do notice a positive difference it seams like this additive was just what I needed for my truck which is on the furthest from stock scale you can be on a 99-03 7.3 (both inside and out). If I can modify this review later I will as I’m currently flushing the redhead Steering gearbox/power steering pump fluid out because I had read you can add a little of those Archoil 9100 to that system and it can improve it too (double bonus) but this review now is only for the Archoil 9100. Hopefully this review will help others like me who consider reviews of 1st hand encounter/real life experience more valuable than some competitors paid promo on a scripted show and video uploaded by Someone who was just endorsing a competitors product this week but last week was endorsing a competitor who’s product was debunked as a bottle of nothing. Needless to say I made my own decision with Archoil and will repeat this decision for my stock 97OBS F350 also. Very happy with this decision and will definitely consider other Archoil products (diesel fuel additives) very soon too.
