For engines, limited slip differentials and motorcylces, use 1.2 oz of AR9100 per quart of conventional or synthetic oil.

For all Power Strokes, use 16 oz of AR9100 every oil change to eliminate & prevent stiction.

For gear oil, hydraulic oil and power steering fluid, use 3.2 oz of AR9100 per quart.

AR9100 is suitable for use in all Diesel & Gas engines. For 6.0L and 7.3L Power Stroke engines, AR9100 has the added benefit of eliminating stiction issues.

Oil alone fails to fully protect your engine, especially under tough conditions. AR9100 Friction Modifier enhances your motor oil’s properties to reduce wear, prevent corrosion, and extend engine life, keeping engines cleaner and running longer—a benefit for both new and high-mileage vehicles.

AR9100 helps clear deposits, reduce friction, and improve fuel efficiency, revitalizing performance. With our no-questions-asked 100% Money Back Guarantee, you can feel confident in the results.

Maximize Power with Advanced Friction Reduction

Excessive engine friction causes power loss, reduced fuel efficiency, heat, noise, and vibration, leading to wear and a less comfortable drive.

AR9100 provides vital lubrication to reduce wear and keep components running smoothly throughout the entire oil cycle and is proven to reduce wear by up to 43% in ASTM testing.

Smoother, quieter operation
Lower friction boosts power output
Reduced engine heat and vibration

Protect Your Engine with a Lubricating Shield

AR9100 creates a solid lubricating barrier that protects engines, gearboxes, and hydraulic systems under extreme pressure. Unlike zinc-based additives, it withstands high stress to enhance durability and performance.

In ASTM testing, AR9100 increased a branded lubricant's load-carrying ability from 3,964 lbs to over 4,500 lbs, significantly improving its anti-wear and friction reduction properties.

Provides strong anti-wear protection
Resilient under extreme pressure
Extends component life

Extend Oil Life for Greater Savings

AR9100 enhances the oxidative stability of engine oil, slowing degradation and extending oil drain intervals. By preventing sludge and deposits, it helps keep passages clear, leading to longer oil life and better engine health.

Blackstone Laboratories tests showed that oil with AR9100 had similar degradation at 10,000 miles as untreated oil at 5,500 miles.

Extends oil drain intervals
Reduces the buildup of sludge and deposits
Prevents costly maintenance

Does Your Truck Suffer From Stiction?

HEUI systems in 6.0L and 7.3L Power Stroke engines use oil pressure to build fuel pressure in the injectors, but heat and pressure degrade the oil over time, creating deposits in spool (or poppet) valves.

This static friction, or "stiction," can disrupt injector firing, leading to hard starts, rough idling, power loss, bucking, and smoke. The gradual build-up significantly impacts performance due to the unique HEUI design that subjects oil to extreme stresses. Symptoms include:

Sluggish starts
Rough operation
Reduced power until the engine warms up

Revive Your Injectors for Restored Power

AR9100’s advanced formula dissolves these deposits and forms a lubricating film that reduces friction within the injectors, restoring smooth operation.

Clears out deposits causing stiction
Reduces friction for smoother starts
Improves injector firing consistency
Enhances cold start performance

"Seeing this F-350 go from a cold-blooded, rough-running basket case to a truck that ran as smooth as it did the day it left the dealership definitely made believers out of us."

Unlock Your Engine’s Potential with AR9100

Stiction leads to power loss and reduced engine response, which can make your Power Stroke feel sluggish. By removing residue build-up and minimizing internal friction, AR9100 helps restore the engine's full potential, delivering more power and a smoother, more responsive drive.

Enhances power and throttle response
Minimizes lag from friction and wear
Restores engine performance

Best product I've used

Hello,

I wanted to share my review of Archoil AR9100 Friction Modifier.

I've been impressed with what this product offers in terms of engine protection and lubrication. AR9100 it does just what it's designed to do and that is help reduce friction and wear, minimize engine noise and vibration, and provide additional protection during cold starts.I believe AR9100 is a great product for anyone who want to take preventative steps toward protecting their engines and extending the life of critical components. I've used it in 3 vehicle's and my generators

Overall, Archoil AR9100 is a product worth considering for anyone serious about engine maintenance, performance, and long-term protection.

Best regards,

My 7.3 loves it

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.

Definitely worth buying

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.

I think it works better than advertised

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.

SEND IT !! YOU WONT BE SORRY

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

A $200 tune up.

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

Life saver

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.

Miracle Sauce

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!

2005 6.0 power stroke.

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.

Just started to use this product

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

97 7.3

Works good I’d say it’s got 30 percent more power, kinda I like took 300k miles off.

I'm not sure

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.

Base on the Fact not by Review

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.

THIS **** WORKS....

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....

Excellent Product

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.

AR9100

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

Good stuff!

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.

Old reliable.

I just cannot believe how much better my old 2007 F350 runs with this product.

7.3 stiction

Fires right up, no smoke, no chugging. Works great!

GOOD STUFF

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 .

Really pleased.

The product really does the trick on my 2007 Ford F-350. It just turned 306,000 miles. Love Archoil

AR9100 FAQs

To maintain the products benefits we recommend adding AR9100 to every oil change.

We recommend adding AR9100 at the time of your oil change.

Methods of adding AR9100 at an oil change include pre-treating your engine or pre-treating your oil. If your oil change is carried out at a shop, bring your bottle of AR9100 and ask the attendant to add the product.

For more detail on methods of adding AR9100, click here.

Yes, but if AR9100 is added to used oil which will be drained soon it would need to be replaced at the next oil change. If an oil change is coming up consider waiting until then to add AR9100 so it can be used for a full oil drain, or consider changing your oil when you add AR9100 so it goes in with fresh oil.

When adding AR9100 to used oil, make sure there is room by draining some oil out beforehand. Make sure not to add AR9100 to an already full crankcase, doing so will exceed your engines maximum oil capacity and can cause engine damage. If your dipstick shows that the oil is below the maximum mark, you can usually add AR9100 without draining oil out.

For all Power Strokes remove ½ a quart (16 oz) of oil from the engine before adding a 16 oz bottle of AR9100. If you are adding AR9100 during an oil change use less oil so there is room.

Yes. AR9100 is suitable for use in both synthetic and conventional engine oil.

No, We don't recommend using AR9100 in automatic transmissions.
