However, smaller engines have smaller clearances and hotter operating temperatures, which places more stress on motor oil, especially at higher miles. Mobil 1 High Mileage motor oil can easily withstand this additional stress. Specially formulated for vehicles with more than 75,000 miles, Mobil 1 High Mileage motor oil helps protect critical engine parts in high mileage engines.
Mobil 1 High Mileage oils are designed to help extend engine life in high mileage engines. These advanced full synthetic motor oils feature:
A proprietary blend of high-performance synthetic base oils that deliver up to 500,000 miles of proven protection
Higher base oil viscosity to help reduce leaks and provide better high-temperature protection†
A boosted level of seal conditioner to protect engine seals because, over time, rubber seals can harden or shrink, resulting in oil leaks
