Editor's Pick: If your car has over 75,000 miles, aging engine seals can lead to oil consumption. This oil is specifically designed for high-mileage vehicles, softening hardened seals to reduce oil loss. It contains zinc and phosphorus anti-wear additives that form a protective film on metal surfaces during cold starts, minimizing dry friction. The 5-quart size is perfect for one oil change, and you'll notice smoother throttle response afterward.
