I used the can with Sunoco Super Unleaded gas in my 2019 F-150 with the V-8 engine. I then travelled from VA to GA (8 hour drive) and I definitely noticed a difference. Pick up to merge onto the highway and passing other vehicles was a lot better and I logged 20.2 miles per gallon, which is at least an improvement of 2 MPG. My truck also idled so great that you wouldn’t even think it was running. Highly recommend this product! Review: Great product at a great price!! - Great product!!! Several dollars cheaper than the auto parts store!!! The top fuel system cleaner!!!

Several dollars cheaper than the auto parts store!!! The top fuel system cleaner!!! Highly recommend!!! ### ⭐⭐⭐⭐⭐ Fuel system additive/cleaner *by J***K on March 3, 2026* I did not look at any of the inside items like the top of the pistons or the valve stems or anything like that but as far as performance, my vehicle which is a 17 suburban 1500 I got better gas mileage, and the engine certainly ran cleaner than it was. Hope some find this review helpful. I also use royal purple oil in several of my vehicles. I certainly like the brand. The product comes with an attachable fill tube, which makes getting it in the fuel tank a lot easier. Note: the deeper your fuel system inlet is the better off you’ll be so you don’t spill. ## Frequently Bought Together - Royal Purple Max-Clean Fuel System Cleaner and Stabilizer 11722 20 Ounce (Pack of 2) - Royal Purple Max Boost Octane Booster - 16 oz. - Royal Purple 18000 Max Atomizer Fuel Injector Cleaner, 6 fl. 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.kr/products/683097287-max-clean-fuel-system-cleaner-and-stabilizer-11722-20-pack](https://www.desertcart.kr/products/683097287-max-clean-fuel-system-cleaner-and-stabilizer-11722-20-pack) --- *Product available on Desertcart South Korea* *Store origin: KR* *Last updated: 2026-05-10*
