  • Price?
Size: AR9100 (16oz)
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. ... show more

  • This actually works

This stuff actually makes a difference in my 7.3. I never had a super long start problem but it did make it start faster and easier and drivability was improved.

  • Running way better
Size: AR9100 (16oz)
I heard about this product a long time ago from a buddy that used it and I never bought it. Well I had been having issues with my 2003 6.0 stalling out and having it towed several times. I changed the fuel filters and put additives in gas ran some what better. I added this to my existing oil without an oil change and getting near change time but added anyways and I’m not sure if it’s 100% because of this additive but truck injectors seem to be running smoother and a little quieter then normal and has not stalled out fires up smoother and quicker. So far I am a believer of it and will use it again. If you have a 6.0 I recommend trying it out and see if you notice a difference. I give it a 10 star and hoping it gives my old 6.0 a new life to keep me going to work. ... show more

  • This is the fix for Ford Powerstroke 6.0L stiction
Size: AR9100 (16oz)
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.) ... show more
