AR9100 Oil Additive (16oz) for All Vehicles - Powerstroke Cold Starts, Eliminates Injector Problems

I recently purchased the Archoil AR9100 Oil Additive and I have to say that I am extremely impressed with its performance. The product is made of high-quality materials and has a number of beneficial properties that have significantly improved the performance of my vehicle. One of the things I appreciate most about the AR9100 is its ability to reduce friction and wear on engine components. Since using this product, I have noticed a significant reduction in engine noise and an improvement in fuel efficiency. The AR9100 also seems to be helping to extend the life of my oil, as it has been able to maintain its viscosity for longer periods of time. The only downside to the AR9100 is that it is quite expensive, especially when purchased on Amazon. While the product is definitely worth the price, I can understand why some people might be hesitant to spend so much on an oil additive. That being said, I believe that the long-term benefits of using the AR9100 more than justify the cost. Overall, I would highly recommend the Archoil AR9100 Oil Additive to anyone looking to improve the performance and longevity of their vehicle. It is a high-quality product that is sure to deliver excellent results. Just be prepared to pay a bit of a premium for it.

Some say oil additives don't help and in a lot of cases I would agree. This is not one of them! This stuff pretty much cured my stiction problem on my 6.0. where as before I was relegated to staying at hotels where I could plug in a extension cord so I could use my trucks block warmer, so it would start on cold mornings, now I can count on it starting without having to plug it in. And then when I switched to Rotella full synthetic oil with the Arch Oil additive it runs like the day I bought it new! So I don't care what some experts say, in real world applications, this stuff works!

I’ve been using these products for a few years now. I did notice our 2005 Ford F-250 Super Duty’s engine runs quieter with it. We haven’t seen much improvement in the fuel milage though.

Helped stop the misfire at idle on my 2004 F350 6.0 Powerstroke. Misfire stopped after 50 miles when Archoil was added. truck has ran perfect since.

I have used this twice now on my 2004 6.0L diesel. It's amazing and works when others do not. For my last oil change, I went back to a 15W-40 Amsoil product and instead of using the Archoil additive, I tried a massive amount of a competitor's product... 64 oz. of Hot Shot's Secret Stiction Eliminator . This was a royal, big mistake. The first startup was a nightmare, and I immediately blamed the new oil and the bad additive. It sounded and smelled like my truck was going to need expensive injector work, belching white smoke and stumbling like an engine that jumped a timing belt. This wasn't all... I went ahead and checked my FICM voltage, found out that it was low, and ordered a new FICM. Well, the FICM improved the stiction a lot and made cold starts better. But it didn't go the whole way, and things during this cold winter started to get bad. Every trip I took, the stiction would be obvious at low rpm and high load... around 1400 to 1900 rpm, 5th gear, 45 to 65 mph, and going up hills with around 10 psi boost. The truck shakes, the passengers ask me what's wrong, and it's just unacceptable surging until I can force a downshift. Higher rpms are generally fine (4th gear, 2300 rpm, turbo singing its tune). So after a couple of weeks of better FICM voltage, the fuel injector stiction was bad again. It was actually more noticeable once the engine was warmed up rather than cold (like with the bad FICM). It was now time for another bottle of additive, this time just 16 oz of Archoil. I checked oil, added the Archoil, and drove a little to park it at the house. The next morning was the real test. It started great, and stiction had disappeared!! Yea. By the end of the day, having driven 100 miles or so, I could tell that about 75 or 80% of the stiction was gone, with a little low rpm stiction occurring at times. By the end of a week, I would say that 95% of it is now gone. Remember, this is with an already crazy amount of another product called "stiction eliminator" that hadn't done hardly anything. 2 weeks in, and I believe that they Archaic has achieved 100% stiction elimination. So having used Archoil twice now, I'd say that it should cover 80 to 99% of the stiction in the Ford Powerstroke 6.0L diesel. It did "wear out" after a long oil drain interval for me, and it may not eliminate all of the stiction. My only alternative is to go back to the Rev-X product if this doesn't cut it. But for now, I am an Archoil fanboy, and I would recommend it. I'll leave it in the truck for another good couple of months and see if and when it "wears out" again. I'm still impressed that just 16 oz of this product did so well! (My review of the Hot Shot's Secret covers some more details.)

I bought this and put it in a 1999 f350 7.3. It almost immediately quieted it down and made starting easier. However, it also started a small oil leak that was not there before. This must have an effect on seals.

I bought a 2006 F250 with the 6.0L and about 380,000 miles on it! Did not have hard stiction issues but heard about this product and what it could do so i gave it a try. Background: I found out the previous owner had been using synthetic oil (dont remember the brand) after i had already put in Delo 15w-40 regular grade with my first oil change. I could tell there was something different by the first few times starting. It did not start as quickly and sometimes it would run for a second then die and would start on the next try. So i bought and added the AR9100 and added to the oil and there was a difference in starting and engine noise the next day after only running for awhile. So yes it will work with Regular grade Diesel Motor Oil also if anyone is wondering, but with the other strains this oil system goes through i wanted to use synthetic. So i wanted to see if just using Rotella synthetic T-6 5w-40 would also solve the known engine issues, so after about 1000 miles, i drained the oil and filled with just Rotella T-6. With the amount of oil that stays in the system along with the oil cooler and HEUI Pump, im sure there was still some Archoil in the system after the drain. I took a roadtrip and changed the oil at about 7500 miles with no issues and seemed to start ok. On my next oil change i stayed with the Rotella T-6 and added a fresh 16oz bottle of AR9100 to the oil. Now with the AR9100 and synthetic T-6 and i can definitely tell a difference in how easy it starts and the smoothness and quietness of the engine even more so than with just the synthetic. Within the first couple days it started easier and sounded much quieter. I could also hear the injectors cycling slowly becoming more steady and smooth like a drum roll. Before they were cycling a little erratic and lopey and didnt sound like all of them were cycling at all. Once the colder weather came i had no issues with stiction or loss of power with temps down in the 30's. I could start it and let it run a few minutes and take off no problems. I will continue to use this product in my 6.0L PSD and may try in my other vehicles to see if any difference. Also i have not compared against RevX or Hot Shots Secret but i know this stuff works and is cheaper and thats good enough for me.

I purchased this product a little over a month ago to use it on my next Oil Change in my 2007 5.7 liter Toyota Tundra with 390000 plus miles. I have used synthetic 0w 20 mobile 1 motor oil in it probably since it got over a hundred thousand miles. Over the past six months or so my engine started making a lot of racket under the hood with what seems to be a timing chain with a loose tensioner. At least that is my diagnosis based on other YouTube videos I have found with the same exact noise. It usually will quiet down once the engine warms up, but recently even that wasn't helping the sound go away so I started looking on the web for oil treatments because it just didn't seem like a normal oil change was doing the trick and looking for a possible cheaper fix because tearing apart the engine to inspect the timing chain would be at least $1,000 if not $2000 or more from a dealer. In addition to adding 9 oz of Archoil into my motor oil since that is what it recommends at 1.2 ounces per quart of oil for gasoline engines, I also decided to use 5 W 20 Mobil 1 extended range high mileage full synthetic oil in this oil change. I'm going on a little over a week now and there is no more clicking or excessive noise going on under the hood. In addition, I usually change the oil every 10,000 Miles when I use the extended-range Mobil 1 motor oil, but this last change I decided to do it early since I wanted to try Archoil out faster and change the oil at 7,000 miles. The oil was super black and now realize that it may be a good idea to start changing the oil at lower mileage intervals because the high mileage extended range motor oil to me is not going to last 20,000 miles as suggested on it's label. So going forward I will most likely start changing the oil in 5000 mile increments too just because I think it will be better on the engine and if this does keep the noise down under the hood it can only be good and give me more peace of mind. As for mileage (mpg) improvement, I have seen a little improvement. However, after an oil change I tend to see a little improvement anyways, but my Tundra on the highway is getting 20.3 miles per gallon this cool morning after driving about 35 miles with two stops along the way as I drove to work, but by the end of the day after it was averaging 18.5 by the time I got home. I wish I could say the same though for city driving, but city driving is worse and usually it brings that average down to 16 to 17 miles per gallon once I have driven on a full tank of gas. Regardless, I think those numbers are pretty good for a 2007 Tundra with over three hundred ninety thousand miles on it (see Odometer picture). If I could have any recommendations for Archoil on improvements for this product it would be to have 18 or 20 oz per bottle instead of 16, because a typical gasoline truck is going to have about eight quarts of oil in it and doing their math that will put you a little short when the next Oil Change comes around to be able to use a bottle on two oil changes. In addition, they really need to have a better View gauge on the side of the bottle with ounce markings for those of us that do not use an entire bottle in one oil change. Overall though I do believe this product has helped quiet my engine down dramatically and has improved gas mileage a little. I have attached a video that I took of my engine back in February 2021 when I first turned it on and the noise was really bad, then a few minutes later after it warmed up and the sound got a little better, then the last 10 seconds or so is after running Archoil through my engine after roughly 300 miles of driving and after the new oil change which I just did on May 16, 2021. The video speaks for itself and I can't guarantee it will do the same for you, but I'm a believer that it helped quiet down my engine dramatically. I hope this review helps someone, and hopefully it will do the same for you. Update: April 11, 2022. I've used Archoil now on several oil changes and it continues to do it's job and keep my engine noise down significantly. My engine will start "acting up" around 5,000 to 7,000 by the noise returning more frequently and know it is time for another oil/Archoil change. I've been very pleased overall and even though this is expensive I believe it is saving me a lot more than a costly repair. My Tundra now has over 414,000 miles on it and still going strong.

I just put 6 oz of this stuff into my 2015 Golf TDI with 310,000 km. I used this product with my regular oil Liqui Moly Toptec 4200 5w30. My TDI seems quieter and runs smoother at lower RPMs. This is great stuff. I'll be using it again next oil change.

great

Great stuff.

I disliked the price, it's good for putting in a Ford Superduty with the reject 6 liter diesel that you just want to flog off onto some unsuspecting young duffer that wants to go around spitting out clouds of black smoke everwhere to kill off a feel athsmatics, until he realizes that the injectors are shot. However as an athsmatic I still need a truck and this was affordable to buy, but requires this quality of additives to keep running successfully. Each time I thought I was going to have to take to dealership to have major engine work and new injectors and scans costs etc, I'd buy another 3pack of this product with injector cleaner etc and in 2 weeks truck can go along in overdrive at 55mph 1400rpm without kicking back, bucking and snorting like a disgruntled union employee:)

My Truck was running like garbage! 2000 F-250 7.3L. Was throwing 9 engine codes, would barely start, usually wouldn't stay running, and if I tried to drive it anywhere it was an adventure, no power, could die anytime and strand you, a nightmare. So I bought this Archoil Diesel Fuel system Cleaner and Archoil9100 Friction Modifier. Expecting to be disappointed but willing to take the risk before spending big money on repairs at a garage. I dumped the products in, and tried to start the truck right away (block heater had been plugged in for hours). It was about -8C out; couldn't get the truck to run for more than 45 seconds. Did this 3 times. The next day after leaving it plugged in over night, it starts under duress, but I manage to get the rpms up to 2000 and hold them there for about 5 mins. I let the truck come back to idle and leave it idling for 30 mins. Come back outside and it's still idling, good sign, sounds good too. Decide I'll drive it 1 km down the road and see how it drives to the gas station, I needed to fill it up after all, I hadn't followed the mix instructions on the fuel system Cleaner. I baby it down the road. Fill it up. Decide to give'r a rip on the way home and it runs awesome, decide I'll rip to the next town and get a coffee, truck pulls and cruises at 120 km/h easily. 2 weeks later ish ans still running great. Also I wiped the engine codes and ran it for a few hundred kms and now only have 1 code that shows up. Awesome product.
