Prior to that it just didn't seem to have the power it should & also sounded like it had bit of an intermittent miss. I read through some boating forums and saw the high praises for this product as being better than the Marine Seafoam. It is made by Mercury so figured I didn't have much to lose and everything to gain. On the recommendation to "shock" the system and clean the fuel system and de-carbon the power head properly, I used a 3oz. to one gallon ratio. I had a small portable 3 gal. fuel tank and once on the lake I switched over from the onboard boat fuel tank to the portable. Almost instantaneously I could tell/feel the difference with the motor....seriously, scouts honor! I continued to run out the small tank varying throttle positions at times. When done with the "shock treatment" the motor was back to running smooth & powerful as it should. Made our fishing trip in MN a pure joy. I'm a firm believer now and will always use this additive as directed for sustained maintenance whenever fueling up. PS....don't forget to add a quality fuel stabilizer as this product does not contain those pertinent ingredients. Fish on. ### ⭐⭐⭐⭐⭐ Its awesome *by on Reviewed in the United States 27 July 2025* The best by far of any cleaner I've seen. Seafood is very good stuff and a favorite go to when in a bind, but this cleaner is 10 times better ## Frequently Bought Together - Quicksilver Quickleen Engine and Fuel System Cleaner - Quicksilver Quickstor Fuel Treatment and Stabilizer - Mercury Marine Quickare Fuel Treatment, 12 Ounces 92-8M0047930 --- ## 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/296827372-quicksilver-mercury-marine-92-8m0047921-quickleen-12-oz](https://www.desertcart.jp/products/296827372-quicksilver-mercury-marine-92-8m0047921-quickleen-12-oz) --- *Product available on Desertcart Japan* *Store origin: JP* *Last updated: 2026-09-11*
