To get the maximum cleaning effect, you should run your tank down to 1/5 of a tank, and THEN put in the whole bottle and drive your car around until you get down to only 25 miles left and THEN, fill up to ONLY a 1/2 tank. This is my only "system" and it's not what they say to do on the bottle. In essence, when you put the bottle in, with 1/2 a tank and THEN, filled up.....you just diluted the strength of that 1 x bottle, by adding all the extra fuel. Try doing what I suggested and it will clean your fuel lines out very very well plus any carbon buildup within your intake or combustion chamber. Good Luck. **Q: How does this work in a 2 stroke outboard boat engine?** A: Thank you for your question, and for considering using Rislone Gasoline Fuel System Treatment (part number 4700) in your 2 stroke outboard motor.

I have a 1998 vw jetta 2.0** A: Yes the entire bottle **Q: how come i was charged tax on a fuel treatment additive being sold by amazon...but not on other items being sold by other sellers** A: From my understanding it’s because the seller is in your state. When you buy product from seller or of state there are no taxes. That’s why the government is trying to pass new laws to be able to tax the products. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Review *by D***. on March 22, 2026* ### ⭐⭐⭐⭐⭐ Review *by L***. on January 19, 2025* ### ⭐⭐⭐⭐⭐ Review *by J***S on October 9, 2023* ## Frequently Bought Together - Rislone 4700 Hy-per Fuel Complete Fuel System Cleaner, 16.9 oz. - Rislone 4102 XTREME LUBE® Maximum Performance Engine Treatment, 16.9 oz. - Bar's Leaks 1000 High Mileage Engine Repair, 16.9 oz | Restores Performance, Increases Compression & Horsepower, Stops Leaks, Noise & Smoking --- ## 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.be/products/8678229-complete-fuel-system-treatment](https://www.desertcart.be/products/8678229-complete-fuel-system-treatment) --- *Product available on Desertcart Belgium* *Store origin: BE* *Last updated: 2026-05-07*
