Start your engines ¿ and start saving with Mobil 1 Advanced Fuel Economy motor oil. Its low-viscosity, advanced full synthetic formulation can help to increase engine efficiency and improve fuel economy. Mobil 1 AFE oil is engineered with a proprietary blend of high performance synthetic base oils, fortified with a precisely balanced component additive system to provide overall lubrication and wear-protection performance for many driving styles and conditions.

Features include:

• Low viscosity, advanced full synthetic formula - helps increase engine efficiency and improve fuel economy, based on 0.2 to 2.3 percent potential fuel economy improvement obtained by switching from higher viscosity oils to a 0W-20 or 0W-30 grade. Actual savings are dependent upon vehicle/engine type, outside temperature, driving conditions and your current motor oil viscosity.
• Outstanding thermal and oxidation stability - helps reduce oil aging for long-lasting protection
• Outstanding low-temperature capabilities - supports quick cold-weather starting and provides fast protection to help extend engine life
• Precisely balanced additive component system - provides excellent overall lubrication and wear protection performance for many driving styles and conditions, from mild to severe, where a 5W-20 or 0W-20 is recommended
