Mobil 1 Delvac ESP 5W-40

Mobil Delvac 1™ ESP 5W-40 

Engineered for the toughest jobs, Mobil Delvac 1™ ESP 5W-40 is an advanced full synthetic heavy-duty diesel engine oil designed to extend engine life in severe applications. It features state-of-the-art technology that delivers exceptional performance in both modern low-emission engines—including those with DPF (Diesel Particulate Filter) and EGR (Exhaust Gas Recirculation) systems—and older, well-maintained engines. This formula provides the ultimate balance of wear protection, long drain capability, and fuel economy potential. 

Key Features:

• Emission System Protection: Low-ash formulation helps protect exhaust after-treatment devices to maintain engine efficiency and meet cleaner air requirements.
  
• Extended Drain Intervals: Offers unsurpassed oxidation stability, allowing for longer intervals between oil changes while preventing deposit buildup.
  
• Extreme Temperature Fluidity: Delivers exceptional pumpability for smooth, reliable startups in temperatures as low as -35°C.
  
• Heavy-Duty Wear Control: Provides "step-out" wear protection to reduce scuffing and bore polishing, significantly promoting a longer engine life.
  
• Mixed Fleet Versatility: Meets requirements for high-performance gasoline engines (API SN/SM), making it a single-oil solution for mixed commercial fleets.
