API SN licensed and compatible with both gasoline and diesel engines, it offers enhanced engine protection and performance, making it the go-to choice for discerning drivers seeking reliability and longevity. ## Description Motor oil is made from crude oil and is used to lubricate, clean, and cool engines. Types of motor oil include conventional, synthetic, diesel, bio-based, hybrid (blends of conventional and synthetic), and recycled oils. Motor oil varies in weight and viscosity, as well as additives that some manufacturers add to the oil during the refining process. A numerical code system created by the Society of Automotive Engineers (SAE) grades motor oils according to viscosity, the higher the number between 0 and 60, the more viscous (thicker) the oil is. Most consumer motor oils are graded by two numbers, with the first number indicating cold weather (Winter or "W") performance. This oil has a weight of SAE 5W-40, meaning it has an SAE viscosity rating of 5 in cold temperatures and a rating of 40 at normal operating temperature. Always check your vehicle's owner's manual to verify that this is the correct weight of motor oil for your vehicle. This oil is fully synthetic, meaning crude oil is not used in making it. Synthetic oil often provides superior mechanical performance over traditional motor oil, including increased gas mileage and reduced engine wear at extreme temperatures. Its complex method of production means it can often cost more than conventional motor oil. Royal Purple Motor Oil Combines premium base oils with proprietary additive technologies to create high performance motor oils that optimize engine performance and provide superior protection. No special procedures are necessary when upgrading to Royal Purple. Royal Purple motor oil is fully compatible with mineral or other synthetic oils. Royal Purple recommends waiting until the manufacturer's first scheduled oil change in new gasoline engines before upgrading to Royal Purple. Royal Purple's API licensed motor oil delivers superior protection and improves performance in gasoline and diesel engines. Royal Purple's API SN licensed motor oil meets ILSAC GF-5 and Dexos1 1 performance requirements. ## Features - Motor Oil Is Made From Crude Oil And Is Used To Lubricate, Clean, And Cool Engines - Types Of Motor Oil Include Conventional, Synthetic, Diesel, Bio-Based, Hybrid (Blends Of Conventional And Synthetic), And Recycled Oils - Through Creativity, Productivity And Innovation - This Brand Continues To Develop The Finest Automotive Accessories - Increased fuel efficiency ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B000MVRTGK | | Automotive Fit Type | Vehicle Specific Fit | | Best Sellers Rank | #62,696 in Automotive ( See Top 100 in Automotive ) #484 in Motor Oils | | Brand Name | Royal Purple | | Compatible with Vehicle Type | Certain gasoline engines with GM dexos1®, API, and ILSAC engine oil requirements | | Container Type | Can | | Customer Reviews | 4.8 4.8 out of 5 stars (300) | | Global Trade Identification Number | 00641330015403 | | Included Components | Auto part, Automotive Accessories, Replacement and Performance parts | | Item Type Name | 5W40 Synthetic Oil | | Liquid Volume | 1 quarts | | Manufacturer | ROYAL PURPLE | | Manufacturer Part Number | 1540 | | Manufacturer Warranty Description | Manufacturer Warranty | | Model Number | ROY01540 | | Number of Packs | 1 | | SAE J300 Viscosity Grade | 5W-40 | | Size | 1 quart | | UPC | 641330015403 | | Unit Count | 32 Fluid Ounces | | Viscosity Level | Medium to High | ## Product Details - **Brand:** Royal Purple - **Liquid Volume:** 1 quarts - **Package Information:** Can - **SAE J300 Viscosity Grade:** 5W-40 - **Vehicle Service Type:** Certain gasoline engines with GM dexos1®, API, and ILSAC engine oil requirements ## Images ![01540 API-Licensed SAE 5W-40 High Performance Synthetic Motor Oil - 1 Qt. - Image 1](https://m.media-amazon.com/images/I/71xxrGb0dyL.jpg) ## Available Options This product comes in different **Size** options. ## Frequently Bought Together - ROYAL PURPLE 5W40 synthetic Oil 1 quart - Service KIT-Oil FILT --- ## 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.sg/products/2251884-01540-api-licensed-sae-5w-40-high-performance-synthetic-motor](https://www.desertcart.sg/products/2251884-01540-api-licensed-sae-5w-40-high-performance-synthetic-motor) --- *Product available on Desertcart Singapore* *Store origin: SG* *Last updated: 2026-10-16*
