It uniquely solves cold start injector issues in PowerStroke 6.0L and 7.3L engines by lubricating stuck valves, resulting in smoother startups, less engine noise, and extended oil life. Trusted by thousands with a 4.7-star rating, AR9100 delivers extreme pressure protection and improved fuel efficiency for professional-grade vehicle care. ## Description AR9100 is a Nanoboratebased oil additive which forms a solid boundary lubricating film to reduce friction and provide antiwear, extreme pressure and anticorrosion protection to engines, gearboxes and hydraulic systems. AR9100 will result in smoother, more powerful and more efficient operation. AR9100 will reduce wear and help prevent failures during extreme operating conditions. AR9100 also helps keep the crankcase clean and extends oil life. General Applications Add 1.2oz of AR9100 per quart of engine oil to any diesel or gasoline powered vehicle. AR9100 is also safe for wet clutches and limited slip differentials. PowerStroke Application AR9100 fixes injectors in PowerStroke 6.0L and 7.3L trucks and other HEUI Injection vehicles (Navistar T444E and VT365) by cleaning and lubricating stuck spool valves. Stiction is eliminated along with associated cold start problems including rough idling, cylinder misfires and loss of power and acceleration. 16 oz of AR9100 is sufficient for one PowerStroke treatment. How AR9100 Works AR9100 is absorbed on metal friction surfaces where it forms a protective solid boundary lubricating film. AR9100 improves lubricity by filling surface asperities creating a smooth hard film. AR9100 has a lower shear strength than the metal it bonds to so friction between surfaces is reduced (CoF .0373,750 lbs in falex test). This means more power, better fuel economy and less heat from friction as well as a reduction in engine noise and vibration. AR9100’s solid boundary film also provides outstanding extreme pressure and antiwear protection to friction surfaces during extreme operating conditions (falex test failure at 4,000 lbs) including cold starts, heavy loads and high temperature conditions. AR9100’s film quality and strength are enhanced in the presence of extreme pressures and temperatures. AR9100 also cleans the crankcase and extends oil life. ## Features - 16oz AR9100 Friction Modifiertreats one Power Stroke - Reduces wear and extends component life - Reduces engine noise, vibration and heat - For all diesel and gasoline engines, gearboxes, hydraulics, differentials and power steering systems - Fixes 6.0L and 7.3L Power Stroke cold start injector problems ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B005UO70ZO | | Best Sellers Rank | #84,860 in Automotive ( See Top 100 in Automotive ) #327 in Oil & Fluid Additives | | Brand Name | Archoil | | Compatible Material | Diesel and Gasoline Engines | | Container Type | Bottle | | Customer Reviews | 4.7 4.7 out of 5 stars (3,900) | | Global Trade Identification Number | 00608819243337 | | Item Form | Oil | | Item Weight | 16 Ounces | | Liquid Volume | 16 Fluid Ounces | | Manufacturer | Archoil | | Material | Fluid | | Model Number | AR9100-16 | | Number of Items | 1 | | Number of Packs | 1 | | Part Number | FBA_AR9100-16 | | Recommended Uses For Product | Automotive, Mechanical | | Specific Uses For Product | Prevent Corrosion | | UPC | 608819244198 608819243412 608819243337 | | Unit Count | 16 Milliliters | ## Product Details - **Brand:** Archoil - **Item weight:** 16 Ounces - **Liquid volume:** 16 Fluid Ounces - **Material:** Fluid - **Package information:** Bottle ## Images ![Archoil AR9100 Oil Additive (16oz) for All Vehicles - Powerstroke Cold Starts, Eliminates Injector Problems - Image 1](https://m.media-amazon.com/images/I/41MOZ-liECL.jpg) ![Archoil AR9100 Oil Additive (16oz) for All Vehicles - Powerstroke Cold Starts, Eliminates Injector Problems - Image 2](https://m.media-amazon.com/images/I/51cuh5DNjzL.jpg) ![Archoil AR9100 Oil Additive (16oz) for All Vehicles - Powerstroke Cold Starts, Eliminates Injector Problems - Image 3](https://m.media-amazon.com/images/I/516Z6t2OteL.jpg) ![Archoil AR9100 Oil Additive (16oz) for All Vehicles - Powerstroke Cold Starts, Eliminates Injector Problems - Image 4](https://m.media-amazon.com/images/I/51HqrgdNfqL.jpg) ![Archoil AR9100 Oil Additive (16oz) for All Vehicles - Powerstroke Cold Starts, Eliminates Injector Problems - Image 5](https://m.media-amazon.com/images/I/51H05q6yI1L.jpg) ## Questions & Answers **Q: Do you add this stuff in with the engine oil?** A: Yes, add with new oil **Q: how about putting this in rear end oil with locker or limited slip gears..OK to do or not. Thinking too thick for transmission right??** A: You can use this in your rear end and your transmission. You will see great results in both. You can use the 9100 anywhere you want to reduce heat and friction. Not only do we sell the products we also have a fleet of 40+ vehicles that we use the 9100 in engine oil, transmissions, rear ends and power steering systems, also is great if you have front oil bath type bearing. Please let us know if you need anything else. **Q: Does this work in any engine? I haven't read anything to suggest it doesn't but all the reviews come from only Powerstroke owners.** A: It works well in engines using a high pressure oil rail to power the injectors, not sure why you would run it in a Cummins or any other common rail or high pressure fuel/injector nozzle or gas engine, just run rotella t-6 synthetic oil and a good filter to keep those running strong for a very long time.Also nearly any diesel will benefit from a quality fuel additive, I find in all 6 of my trucks (3 brands) that power service diesel kleen will more than pay for itself in fuel Economy improvements alone (about 5-15%). **Q: can you use this with full synthetic oil** A: Yes. I use Synthetic oil, Rotella T6 for diesel applications. It provides better lubrication, for longer intervals. Works great with Archoil. ## Frequently Bought Together - Archoil AR9100 Oil Additive (16oz) for All Vehicles - Powerstroke Cold Starts, Eliminates Injector Problems - Motorcraft- Oil Filter - Motorcraft FD-4616 Fuel Filter --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.jp/products/284275607-archoil-ar9100-oil-additive-16oz-for-all-vehicles-powerstroke-cold](https://www.desertcart.jp/products/284275607-archoil-ar9100-oil-additive-16oz-for-all-vehicles-powerstroke-cold) --- *Product available on Desertcart Japan* *Store origin: JP* *Last updated: 2026-10-30*
