It features advanced zinc/phosphorus anti-wear additives and proprietary Synerlec technology to reduce friction, revitalize seals, and extend oil drain intervals up to 15,000 miles. This oil cleans engine deposits, protects metal surfaces at startup, and supports long-term engine performance, making it ideal for gasoline cars and light trucks seeking enhanced durability and efficiency. ## Description Royal Purple HMX SAE 5W-30 High-Mileage Synthetic Motor Oil, 1 quart is specifically designed to minimize wear and restore lost performance in engines with more than 75,000 miles. Formulated with robust zinc/phosphorus anti-wear compounds combined with Royal Purple's proprietary additive technology Synerlec, HMX is chemically enhanced to revitalize hardened seals, reducing oil consumption common in high-mileage engines. In addition, HMX is fortified with stout detergents to remove engine build-up and deposits, maintain cleanliness and promote engine longevity. The advanced Synerlec technology in HMX provides exceptional film strength, reducing friction and metal to metal contact for peak engine performance. It also provides outstanding oxidation resistance to safely extend oil drain intervals, and an ionic attraction to metal surfaces, providing protection and minimizing wear at start-up. Engineering formulations is a balancing act as engine oil has several key functions to perform. Higher mileage engines require a shift in this balance in certain regards as compared to new engines, such as anti-wear, detergency and preserving and restoring seal elasticity. Recommended for gasoline passenger car and light-truck engines beyond 75,000 miles, HMX can safely extend oil drain intervals up to 15,000 miles or 12 months in unmodified, mechanically-sound engines with proper filtration. When using HMX, Royal Purple recommends first performing two short clean-up drain intervals of 3,000 miles each with HMX to thoroughly clean the engine before extending drain intervals. Royal Purple HMX is suitable for use in engines specifying API service SJ, SL, SM and SN. ## Features - Specifically designed to minimize wear and restore lost performance in engines with more than 75,000 miles - Formulated with robust zinc/phosphorus anti-wear compounds combined with Royal Purple's proprietary additive technology - HMX is chemically enhanced to revitalize hardened seals, reducing oil consumption common in high-mileage engines - Reduces friction and metal-to-metal contact for peak engine performance - Also provides outstanding oxidation resistance to safely extend oil drain intervals, and an ionic attraction to metal surfaces, providing protection and minimizing wear at start-up - Fit type: Vehicle Specific ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B00G3BRNLE | | Automotive Fit Type | Vehicle Specific Fit | | Best Sellers Rank | #5,874 in Automotive ( See Top 100 in Automotive ) #96 in Motor Oils | | Brand Name | Royal Purple | | Compatible with Vehicle Type | Car, Truck | | Container Type | Bottle | | Customer Reviews | 4.9 4.9 out of 5 stars (2,878) | | Global Trade Identification Number | 00641330117442 | | Included Components | Auto part, Automotive Accessories, Replacement and Performance parts | | Item Type Name | High Mileage Synthetic Motor Oil | | Liquid Volume | 32 fluid ounces | | Manufacturer | Royal Purple | | Manufacturer Part Number | 11744 | | Manufacturer Warranty Description | Manufacturer Warranty | | Model Number | 11745 | | SAE J300 Viscosity Grade | 5W-30 | | Size | 1 Quart | | UPC | 641330117442 | | Unit Count | 32 Fluid Ounces | | Viscosity Level | Low to Medium | ## Product Details - **Brand:** Royal Purple - **Liquid Volume:** 32 fluid ounces - **Package Information:** Bottle - **SAE J300 Viscosity Grade:** 5W-30 - **Vehicle Service Type:** Car, Truck ## Images ![High Mileage Motor Oil - Image 1](https://m.media-amazon.com/images/I/71FYuclDYIL.jpg) ## Available Options This product comes in different **Size** options. ## Frequently Bought Together - Royal Purple 11744 HMX SAE 5W-30 High-Mileage Synthetic Motor Oil - 1 Quart - Royal Purple 10-48 Oil Filter --- ## 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.pl/products/14393693-high-mileage-motor-oil](https://www.desertcart.pl/products/14393693-high-mileage-motor-oil) --- *Product available on Desertcart Poland* *Store origin: PL* *Last updated: 2026-08-04*
