Review: Should have found this product years ago. - AR6400-D works well cleaning the soot from my 6.7 Cummins. Regens extended to over 1,000 mile intervals. Will continue to use every 5K miles. A MUST product for diesel engines new and old. Review: It Works! A DPF Miracle! - The DPF warning light came on in my 2014 VW Touareg TDI Lux and it was suggested that I run a tank with this product before I spend a fortune at the dealer. (To be detailed, my tank is 26 gallons, and this bottle will treat 40 gallons. So, I used 3/4 of the bottle and filled my tank. Added the remainder of the bottle and 10 more gallons of diesel when my tank was half empty.) Voila! The light went off within driving about 50 miles and has never come back on. That was a couple of years ago and I now run an Archoil tank about every 6-7 months, for good measure. The fine folks at Archoil recommend every 5,000 miles. I'm probably near that ballpark. Great stuff! ## Features - EASY ONE-BOTTLE USE (2-Pack Value): Includes two 12 oz bottles. Pour into the fuel tank and drive normally. Each bottle treats 30-40 gallons of diesel. Use every 5,000 miles or as needed - RAPID-ACTING DEEP CLEAN: Concentrated diesel fuel system cleaner designed to work quickly on performance-robbing deposits to restore the fuel system - CLEANS INJECTORS FAST: Removes injector deposits and restores spray patterns for smoother running, improved response, and more efficient combustion - RESTORES DPF PERFORMANCE: Reduces deposit buildup to support a cleaner DPF and reduce regeneration frequency - TURBO DEPOSIT CONTROL: Reduces deposit buildup that affects turbo response, supporting smoother acceleration and restored boost - MAINTAIN RESULTS WITH AR6500: Follow up with Archoil AR6500 Diesel Treatment at every fill-up to keep the fuel system clean and address insufficient lubricity and cetane levels in diesel from the pump ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B08H8V5T4G | | Best Sellers Rank | #1,096 in Automotive ( See Top 100 in Automotive ) #5 in Diesel Additives | | Brand | Archoil | | Brand Name | Archoil | | Contains Liquid Contents? | Yes | | Customer Reviews | 4.7 out of 5 stars 2,733 Reviews | | Item Form | Liquid | | Item Volume | 12 Fluid Ounces | | Manufacturer | Archoil | | Material Feature | liquid | | Material Features | liquid | | Number of Items | 2 | | Part Number | AR6400-D-2P | | Scent | Unscented | | Size | 12 Fl Oz (Pack of 2) | | Specific Uses For Product | Bottle | | UPC | 608819244143 | | Unit Count | 24 Fluid Ounces | ## Product Details - **Brand:** Archoil - **Item Form:** Liquid - **Material Feature:** liquid - **Scent:** Unscented - **Specific Uses For Product:** Bottle ## Images ![AR6400-D Diesel Fuel System Cleaner (Two Pack) - Cleans Injectors, Turbo & DPF - Image 1](https://m.media-amazon.com/images/I/71kHAxhwMyL.jpg) ![AR6400-D Diesel Fuel System Cleaner (Two Pack) - Cleans Injectors, Turbo & DPF - Image 2](https://m.media-amazon.com/images/I/81ORS+BjYqL.jpg) ![AR6400-D Diesel Fuel System Cleaner (Two Pack) - Cleans Injectors, Turbo & DPF - Image 3](https://m.media-amazon.com/images/I/81MPnZ1rtjL.jpg) ![AR6400-D Diesel Fuel System Cleaner (Two Pack) - Cleans Injectors, Turbo & DPF - Image 4](https://m.media-amazon.com/images/I/81u87dp0oYL.jpg) ![AR6400-D Diesel Fuel System Cleaner (Two Pack) - Cleans Injectors, Turbo & DPF - Image 5](https://m.media-amazon.com/images/I/71MnDeZwk0L.jpg) ## Available Options This product comes in different **Size** options. ## Questions & Answers **Q: How Come u guys can’t get ur delivery days right says next day then three days later I get my package** A: just the way it is in your area of country and state...rare my orders come later but its usually a holiday..weather or construction **Q: Have an 05 f350 with 6.0 power stroke. Should I use the full bottle in one tank or split it up between 2 fill ups?** A: Been using this stuff for 4 years now 2007 Ford F-350 6.0 with 156K miles and my truck runs ten times better when I use this stuff and I also get a better gas mileage when towing. I’ve always used a whole bottle on a full tank a gas, but you can always try half and see there is any difference. I know it’s pretty pricey but the 6.0’s want to be pampered all the time it’s not even funny. If I don’t do oil service on every 3K miles that truck is like my kids it will start crying... lol. **Q: can it be used on a isuzu yukon 2015 2.5l td twin turbo?** A: Yes, AR6400-D is good for all diesel vehicles **Q: Remove Water?** A: Yes ## Customer Reviews ### ⭐⭐⭐⭐⭐ Should have found this product years ago. *by A***S on April 21, 2026* AR6400-D works well cleaning the soot from my 6.7 Cummins.
