This stuff is helping my truck run great. I live in an area that there is not 1 good fuel station with certified gasoline with cleaning additives. At least not that I have discovered. By adding this product my truck is getting the lubrication it needs and the cleaning agents it requires to keep the injectors plus the O2 sensors healthy. It works and MADE IN THE USA! ### ⭐⭐⭐⭐⭐ had to do some adjustments *by B***U on May 6, 2026* good stuff worked right away ### ⭐⭐⭐⭐ Be careful on dosage *by C***R on January 2, 2026* Good cleaner but watch the dosage. I put around 4 oz in a 1/2 tank and started getting rough idle and stutter/misfire due to dilution and bad combustion. Once I filled up the tank issues were gone. Just be aware and follow recommended dose. ## Frequently Bought Together - Rislone 4732 Fuel Injector Cleaner with Upper Cylinder Lubricant, 32 oz - Rislone 4700 Hy-per Fuel Complete Fuel System Cleaner, 16.9 oz. - Rislone 4102 XTREME LUBE® Maximum Performance Engine Treatment, 16.9 oz. --- ## 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/22583307-rislone-4732-fuel-injector-cleaner-with-upper-cylinder-lubricant-32](https://www.desertcart.jp/products/22583307-rislone-4732-fuel-injector-cleaner-with-upper-cylinder-lubricant-32) --- *Product available on Desertcart Japan* *Store origin: JP* *Last updated: 2026-06-22*
