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 ## Frequently Bought Together - Archoil AR6400-D Diesel Fuel System Cleaner (Two Pack) - Cleans Injectors, Turbo & DPF - Archoil AR6500 Diesel Treatment (40.6oz) Two Pack - Treats 800 Gallons - Additive for All Diesel Vehicles - Archoil Diesel Fuel System Kit - AR6500 Diesel Treatment (40 oz) + AR6400-D Diesel Fuel System Cleaner --- ## 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.pt/products/681772679-ar6400-d-diesel-fuel-system-cleaner-two-pack-cleans-injectors](https://www.desertcart.pt/products/681772679-ar6400-d-diesel-fuel-system-cleaner-two-pack-cleans-injectors) --- *Product available on Desertcart Portugal* *Store origin: PT* *Last updated: 2026-10-02*
