How does Quaker State 5W-20 protect my engine during everyday driving?

This formulation is balanced to form a robust lubricating film that lowers metal-on-metal contact and slows deposit buildup between oil changes. It offers high oxidation resistance so the oil stays effective longer, especially in stop-and-go city use.

• Full synthetic base oils reduce friction and wear.
• Detergent and dispersant additives help limit sludge and varnish.
• Oxidation inhibitors extend oil life and performance.

Will this oil help fuel economy or performance in modern engines?

Yes — the 5W-20 viscosity is chosen to balance protection with lower internal drag, which can improve fuel efficiency compared with heavier grades. Quaker State also formulates this oil to help free up a small amount of horsepower by minimizing friction losses.

• Lower-viscosity flow at operating temperature for reduced parasitic losses.
• Friction-reducing additives aimed at maximizing horsepower retention.
• Suitable for turbocharged and high-revving engines where 5W-20 is specified.
