• Cold-start protection down to -30°F for rapid oil flow
• Oxidation control to slow oil degradation over service life
• Helps keep engines running cooler compared to conventional oil

Will this oil help my vehicle’s fuel economy and component wear?

Mobil 1 High Mileage meets ILSAC GF-6 standards, offering benefits for modern engines including reduced low-speed pre-ignition risk and improved timing-chain wear protection. By minimizing internal friction and keeping deposits in check, it can support efficient operation and component longevity.

• Meets ILSAC GF-6 for modern engine protections
• Helps reduce timing-chain wear and LSPI risk in susceptible engines
• Cleaner internal surfaces can contribute to steady fuel economy
• Proven in lab testing to lower engine temperatures versus conventional oils

How long can I run between oil changes with this product?
