Product Overview & Specifications
S-Oil Seven Red #9 5W-30 is a high-performance, fully synthetic motor oil engineered to deliver superior protection and efficiency for a wide range of modern gasoline and light-duty diesel engines. Utilizing S-Oil’s advanced Very High Viscosity Index (VHVI) Group III hydrocracked base oils, often categorized as a “full synthetic” in many global markets, Red #9 is formulated to provide exceptional thermal stability, oxidative resistance, and shear stability. Its robust additive package includes a balanced blend of detergents, dispersants, anti-wear agents, and friction modifiers, designed to mitigate deposit formation, reduce engine wear, and optimize fuel economy. The “Red #9” designation implies a focus on robust, all-around performance, often suitable for engines requiring higher High-Temperature High-Shear (HTHS) viscosity and robust TBN (Total Base Number) to neutralize acidic byproducts of combustion. This lubricant targets performance-oriented drivers and vehicles demanding longevity and sustained performance under varying operating conditions, particularly those with higher-output gasoline engines or non-DPF-equipped diesel engines.

Recommended Applications & Car Compatibility
S-Oil Seven Red #9 5W-30 is exceptionally well-suited for a broad spectrum of modern gasoline engines, including those featuring Gasoline Direct Injection (GDI), turbochargers, and multi-valve designs. Its robust formulation provides critical protection against Low-Speed Pre-Ignition (LSPI), a common concern in downsized, turbocharged GDI engines, thereby safeguarding pistons and connecting rods. The high HTHS viscosity (typically >3.5 mPa·s for A3/B4 oils) ensures durable film strength and shear stability, making it ideal for high-stress applications in European and Asian marques such as BMW (requiring LL-01), Mercedes-Benz (requiring 229.5), Volkswagen/Audi (requiring 502 00/505 00), and Porsche (A40). While primarily designed for gasoline, its API CF classification and ACEA B4 rating also make it suitable for certain indirect injection, naturally aspirated or turbocharged light-duty diesel engines that do not feature Diesel Particulate Filters (DPF). The balanced additive package ensures effective soot control and wear protection for compatible diesel applications. This oil is particularly advantageous for vehicles operating in diverse climates where a broad operating temperature range is beneficial.
Operating Conditions & Drain Intervals
- Standard Drain Interval: For vehicles operating under normal highway driving conditions with regular maintenance, a drain interval of 10,000 to 15,000 kilometers (or 6,000 to 9,000 miles) or 12 months, whichever comes first, is typically appropriate. Always refer to the vehicle manufacturer’s specific recommendations.
- Severe Service Interval: Under severe operating conditions such as heavy city stop-and-go traffic, frequent short trips, prolonged idling, extensive towing, dusty environments, or extreme ambient temperatures, the drain interval should be reduced. A severe service interval of 5,000 to 8,000 kilometers (or 3,000 to 5,000 miles) or 6 months is generally recommended to maintain optimal engine protection and lubricant performance.
- Temperature Performance: The 5W designation ensures excellent cold-start performance, allowing for rapid oil circulation and reduced wear during critical startup sequences in sub-zero temperatures, typically down to -30°C to -35°C. At the 30 hot viscosity grade, it maintains a robust lubricating film under sustained high-temperature operation, effectively managing engine heat and resisting thermal breakdown during heavy loads, high-speed driving, and extended idling in hot climates. Its synthetic base and advanced additive system provide superior oxidation resistance compared to conventional oils, enhancing stability across the entire operational temperature range.
Usage Restrictions & Limitations
While S-Oil Seven Red #9 5W-30 is a versatile lubricant, specific applications are not recommended. Due to its ACEA A3/B4 classification, it inherently features a higher sulfated ash content (typically >1.0%) compared to low-SAPS (Sulfated Ash, Phosphorus, Sulfur) oils. Therefore, it MUST NOT be used in vehicles equipped with Diesel Particulate Filters (DPF) or other sensitive exhaust after-treatment systems that specifically mandate an ACEA C-category oil (e.g., C1, C2, C3, C4, C5, C6). Using Red #9 in DPF-equipped vehicles will lead to premature clogging and failure of the DPF. Furthermore, while its 5W-30 viscosity is broadly compatible, it should not be used in engines specifically requiring different viscosities such as 0W-20, 5W-20, or higher viscosity grades like 0W-40, 5W-40, or 10W-40 if the manufacturer explicitly prohibits other grades. Adherence to OEM viscosity and specification requirements is paramount to avoid potential issues such as increased wear, reduced fuel economy, or impaired emissions system function. This oil’s robust formulation is generally compatible with modern engine seal materials; however, for very old engines with original, potentially degraded seal compounds, a switch to a modern synthetic may occasionally expose existing leaks, although this is rare and not specific to this product.
