Manufacturer's description

Mobil 1 FS x2 5W-50 is a select member of the Mobil 1 range, ExxonMobil's flagship synthetic engine oil line. It is engineered to deliver excellent all-round protection for engines operating in tough conditions, combining high-performance synthetic base stocks with a precisely balanced additive system that reinforces the protective oil film at high temperature while keeping strong oil flow at low temperature. It suits the latest generation high-powered gasoline and diesel (without particulate filter) engines, whether turbocharged or naturally aspirated, as well as older gasoline engines requiring a high-viscosity oil under earlier API standards. It is well suited to motorsport applications and extreme driving conditions such as high temperature, high load and towing, and also provides the extra protection that older or high-mileage vehicles (over 100,000 km) can demand, with a full SAPS additive system supporting drain intervals up to 20,000 km. Key benefits include prevention of harmful deposit buildup, enhanced cleaning for higher-mileage engines, improved protection against variable fuel quality, a 5W low-temperature grade for easy cold starts, a 50 high-temperature grade to limit wear and oil consumption, and protection against Low Speed Pre-Ignition (LSPI) and timing chain wear in GTDI engines. Approvals and specifications include MB-Approval 229.3, Porsche A40, FIAT 9.55535-M2, API SN/SN PLUS/SP/SQ and ACEA A3/B3-16 and A3/B4.

Applications

  • Suitable for the latest generation of high-powered vehicles with petrol and diesel engines (without particulate filter), turbo-charged or naturally aspirated, as well as for older gasoline engines calling for high-viscosity engine oils meeting prior API standards.
  • Well suited for motorsport applications and extreme driving conditions (high temperatures and loads, car towing, etc.).
  • Also helps provide the extra protection that older vehicles and vehicles with higher mileage (over 100,000 km) can demand.

Performance & benefits

  • Combines a proprietary blend of high-performance synthetic basestocks fortified with a precisely balanced component system, providing a reinforced protective oil film at high temperature while still ensuring superb oil-flow properties at lower temperatures.
  • Its full-SAPS additive system also contributes to exceptional cleaning power, engine wear protection and lubrication, up to a 20,000 km maximum oil-drain interval.
  • Excellent protection for the engine by helping prevent the buildup of harmful deposits.
  • Enhanced cleaning technology for cars with higher mileage (100,000 km+).
  • Improved protection against variable fuel quality.
  • Low-temperature viscosity grade (SAE 5W) to help protect the engine during cold start-up.
  • High-temperature viscosity grade (SAE 50) to help build a strong lubricating oil film to protect against wear and to help reduce oil consumption or leaks in high-mileage engines.
  • Helps prevent Low-Speed Pre-Ignition (LSPI) occurrences and timing-chain wear in gasoline direct-injection turbocharged engines (GTDI).
