Product Overview & Specifications
Ravenol VMO SAE 5W-40 is a high-performance, fully synthetic engine oil engineered with a meticulously balanced blend of advanced Polyalphaolefin (PAO) and cutting-edge hydrocracked (HC-Synthetic Group III+) base stocks. This formulation targets superior lubrication performance while adhering to stringent emissions standards. Categorized as a “Mid SAPS” (Sulfated Ash, Phosphorus, Sulfur) lubricant, VMO 5W-40 is specifically designed to protect modern exhaust aftertreatment systems such as Diesel Particulate Filters (DPF), Gasoline Particulate Filters (GPF), and Three-Way Catalytic Converters (TWC) by minimizing ash accumulation and poisoning. Its core marketing claims revolve around exceptional wear protection, extended drain intervals, robust thermal and oxidative stability, and sustained engine cleanliness, even under severe operating conditions. The real-world target audience comprises owners and professional service centers catering to modern European gasoline and diesel vehicles, particularly those equipped with forced induction (turbochargers/superchargers) and sophisticated emissions control systems requiring ACEA C3 specifications and specific OEM approvals from manufacturers like BMW, Mercedes-Benz, and the Volkswagen Group.

Recommended Applications & Car Compatibility
Ravenol VMO SAE 5W-40 is meticulously formulated for a broad spectrum of contemporary European and Asian engines. Its specific “Mid SAPS” profile (ACEA C3) makes it an indispensable choice for vehicles equipped with Diesel Particulate Filters (DPF) and Gasoline Particulate Filters (GPF), ensuring their longevity and performance by preventing ash build-up. This oil is particularly well-suited for:
- BMW: All diesel engines requiring BMW Longlife-04 (LL-04), as well as specific gasoline engines where LL-04 is specified (e.g., N-series, B-series engines).
- Mercedes-Benz: Both gasoline (M-series) and diesel (OM-series) engines requiring MB-Approval 229.31 or 229.51, especially those with BlueTEC or AdBlue systems.
- Volkswagen Group (Audi, VW, Skoda, SEAT): Gasoline and diesel engines requiring VW 502 00 / 505 00 / 505 01, including Pumpe Düse (PD) diesel injectors and modern TSI/TFSI units often fitted with GPF.
- Porsche: Specific models requiring Porsche A40, demonstrating its robustness even in high-performance applications, despite its C3 classification.
- General Motors: Vehicles requiring GM dexos2 specification.
- Chrysler, Fiat, Ford: Meets requirements for Chrysler MS-11106, Fiat 9.55535-S2, and Ford WSS-M2C917-A.
Its robust formulation provides exceptional performance in engines with turbochargers by resisting thermal breakdown and preventing coking in hot turbo bearings. For Gasoline Direct Injection (GDI) engines, VMO 5W-40’s advanced additive package, including potent detergents and dispersants, assists in mitigating the formation of harmful deposits on intake valves and pistons, while its low volatility characteristics and robust film strength contribute to reducing the risk of Low-Speed Pre-Ignition (LSPI).
Operating Conditions & Drain Intervals
- Standard Drain Interval: For vehicles operating under typical highway conditions and routine driving cycles, a drain interval of 10,000 to 15,000 kilometers (approximately 6,000 to 9,000 miles) or one year is generally recommended, aligning with specific OEM guidelines. Regular oil analysis can further optimize these intervals.
- Severe Service Interval: Under demanding conditions such as frequent short trips, prolonged idling, heavy city traffic, consistent stop-and-go driving, towing, or operation in extreme ambient temperatures (both hot and cold), the drain interval should be reduced to 5,000 to 7,500 kilometers (approximately 3,000 to 4,500 miles) or six months, whichever comes first, to ensure optimal engine protection and lubricant efficacy.
- Temperature Performance: The 5W designation ensures excellent cold-start performance, providing rapid oil flow and lubrication to critical engine components even in sub-zero temperatures (effective down to -30°C to -35°C), significantly reducing start-up wear. The 40 hot viscosity grade maintains a robust and stable lubricating film under extreme engine loads, high operating temperatures, and elevated ambient conditions, resisting shear thinning and thermal degradation. This consistent viscosity protects against metal-to-metal contact and ensures effective heat dissipation, even during sustained high-speed driving or heavy hauling.
Usage Restrictions & Limitations
While Ravenol VMO SAE 5W-40 is a highly capable lubricant, certain applications and engine types should avoid its use:
- High-SAPS Requirements: This oil is a “Mid SAPS” (ACEA C3) formulation. It should NOT be used in older engines or vehicles that explicitly require “High SAPS” (ACEA A3/B3, A3/B4) oils. The reduced levels of sulfated ash, phosphorus, and sulfur, while critical for DPF/GPF protection, may not provide the same level of anti-wear (e.g., ZDDP) or TBN (Total Base Number) capacity needed for optimal protection in engines designed for a different additive chemistry, potentially leading to premature wear or reduced acid neutralization.
- Specific Viscosity Requirements: Do not use Ravenol VMO SAE 5W-40 in engines that strictly specify a different viscosity grade or a lower HTHS (High-Temperature High-Shear) viscosity, such as 0W-20, 0W-30, 5W-30 (especially ACEA C1/C2 or certain OEM-specific low-viscosity oils). Using a mismatched viscosity can lead to reduced fuel economy, increased emissions, or insufficient lubrication due to incorrect oil film thickness for tighter engine clearances.
- Engine Seal Compatibility (Older Engines): While modern synthetic base oils are generally compatible with various seal materials, the specific additive package of C3 oils might not offer the same seal conditioning properties found in some older conventional or semi-synthetic formulations. For engines predating the widespread adoption of modern emissions standards (e.g., pre-2004), consulting the OEM specification is paramount to avoid potential issues.
- Diesel Engines Without Aftertreatment: While acceptable, using a Mid SAPS oil in older diesel engines without a DPF, which typically require a High SAPS ACEA A3/B4 oil, may not provide the maximum TBN or anti-wear additive content that such engines were designed for, potentially shortening the oil’s effective lifespan in a non-DPF application.
