Great price online compared to my local auto parts store, and the performance is impressive. My engine feels smoother, throttle response improved, and it’s reassuring knowing it cleans and stabilizes the fuel system. Excellent value for a high-quality product I’ll definitely keep using. ### ⭐⭐⭐⭐⭐ Top notch stuff *by M***L on May 27, 2026* One of the best cleaners Ive used for injectors, gives better gas mileage and powerfully cleaning your fuel system ### ⭐⭐⭐⭐⭐ Works Really Well *by R***. on April 13, 2026* I purchased a 20 oz can of this at AutoZone ($18.99 + tax). 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! ## 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.ie/products/683097287-royal-purple-max-clean-fuel-system-cleaner-and-stabilizer-11722](https://www.desertcart.ie/products/683097287-royal-purple-max-clean-fuel-system-cleaner-and-stabilizer-11722) --- *Product available on Desertcart Ireland* *Store origin: IE* *Last updated: 2026-06-14*
