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 fuel system cleaner - Need a cleaner to clean from fuel tank to exhaust stroke? Boom, here you go. This is a great and strong product to really clean carbon deposits and the fuel system entirely. And protects for future. Easy to use and comes with a little funnel if you don’t have one. Good price and doesn't smell. ## Features - The information below is per-pack only - 3-in-1 fuel additive keeps new engines clean and improves vehicle's performance - Improves fuel economy an average of 3.2 percent - Increases horsepower an average of 2.6 percent - Reduces hydrocarbon, NOx and CO emissions (on average 12, 13 and 18-percent respectively) - Fit type: Vehicle Specific ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B0CXPWXZFM | | Best Sellers Rank | #605 in Automotive ( See Top 100 in Automotive ) #3 in Fuel System Cleaners | | Brand | Royal Purple | | Customer Reviews | 4.7 4.7 out of 5 stars (2,967) | | Date First Available | November 7, 2025 | | Is Discontinued By Manufacturer | No | | Item Weight | 2.5 pounds | | Item model number | 11722 | | Manufacturer | Royal Purple | | Manufacturer Part Number | 11722 | | Product Dimensions | 2.63 x 2.63 x 9.73 inches | ## Product Details - **Brand:** Royal Purple - **Item Volume:** 20 Fluid Ounces - **Unit Count:** 2.0 Count - **Number of Items:** 2 - **Item Weight:** 2.5 Pounds ## Images ![Max-Clean Fuel System Cleaner and Stabilizer 11722 20 (Pack of 2) - Image 1](https://m.media-amazon.com/images/I/71FCV+QAFpL.jpg) ## Available Options This product comes in different **Size** options. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Works Really Well *by R***. on April 13, 2026* I purchased a 20 oz can of this at AutoZone ($18.99 + tax).
