Featuring potent polyether amine detergents and friction modifiers, it cleans stubborn injector deposits, reduces emissions, protects against ethanol damage, and improves combustion efficiency. EPA and CARB compliant, it’s the ultimate upgrade for drivers seeking enhanced engine reliability and eco-conscious performance. ## Description Royal Purple® Max-Restore™ High Mileage is a highly concentrated, high-performance fuel system treatment, specially formulated to restore lost performance and economy in high mileage vehicles. This unique formulation solves problems experienced with today’s direct injection engines, but can be used with any type of fuel injection. Max-Restore High Mileage contains a high dose of polyether amine (PEA) & proprietary detergents that quickly clean stubborn, long-term, legacy deposits that clog injectors and provides a protective barrier to keep new deposits from forming. This optimizes injector spray patterns and better atomizes fuel as it enters the combustion chamber resulting in enhanced power and performance, reduced emissions, smoother idle, and quicker / easier starts. It also utilizes a friction modifier to reduce wear in the upper cylinder to help extend engine life and improve fuel economy. Max-Restore High Mileage also stabilizes ethanol, which chemically breaks down and causes harmful effects in an engine. ## Features - RESTORES FUEL ECONOMY – Increased fuel economy by an average of 6% vs. dirty injectors - LOWERS EMISSIONS – Cleaned injectors improve combustion, reducing CO, NOx, and unburned hydrocarbons - INCREASED RELIABILITY – Provides wear protection in the combustion chamber & reduces damage caused by high-ethanol fuels - MAXIMIZED DEPOSIT REMOVAL – Required injection time reduced over 70% vs. dirty injectors (normalized to new injectors) - EPA and CARB COMPLIANT – safe and legal for use in all 50 states ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B0D67F93X7 | | Best Sellers Rank | #130,994 in Automotive ( See Top 100 in Automotive ) #132 in Fuel Additives | | Brand | Royal Purple | | Brand Name | Royal Purple | | Customer Reviews | 4.6 out of 5 stars 268 Reviews | | Included Components | 1 Bottle Fuel Treatment | | Item Type Name | High Mileage Fuel System Treatment | | Manufacturer | Royal Purple | | Model Number | 18001 | | Number of Items | 1 | | Part Number | 18001 | | Size | 6 Fl Oz (Pack of 1) | | UPC | 641330180019 | | Unit Count | 6 Fluid Ounces | ## Product Details - **Brand:** Royal Purple - **Manufacturer:** Royal Purple - **Number of Items:** 1 - **UPC:** 641330180019 - **Unit Count:** 6.0 Fluid Ounces ## Images ![Royal Purple 18001 Max-Restore High Mileage Fuel System Treatment - 6 Ounce - Image 1](https://m.media-amazon.com/images/I/617Qsmz2ExL.jpg) ![Royal Purple 18001 Max-Restore High Mileage Fuel System Treatment - 6 Ounce - Image 2](https://m.media-amazon.com/images/I/61WgCpNk-YL.jpg) --- ## 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/634273254-royal-purple-18001-max-restore-high-mileage-fuel-system-treatment](https://www.desertcart.jp/products/634273254-royal-purple-18001-max-restore-high-mileage-fuel-system-treatment) --- *Product available on Desertcart Japan* *Store origin: JP* *Last updated: 2026-11-12*
