Some engines are asked to work harder than others. Quaker State^® Enhanced Durability™ Synthetic Blend motor oil coats your motor with a low-friction, heat-resistant film that reduces metal-to-metal contact when temperatures and stress levels are high.

Quaker State^® Enhanced Durability™ Synthetic Blend motor oil:
• Excellent protection against friction-related wear*
• Improved resistance to engine stress at high RPMs and under heavy loads**
• Enhanced resistance to thermal and viscosity breakdown
• Excellent lubrication at low and high temperatures

*As measured in ASTM Sequence IVA test, using SAE 5W-30 engine oil. **Comparison based on Quaker State^® Advanced Durability™ conventional oil.
