Pennzoil 1-Qt. 10W30 High Mileage Vehicle Motor Oil, specifically designed for vehicles with over 75,000 miles. It features active cleansing agents that continuously prevent dirt and contaminants from forming performance-robbing deposits, ensuring engine cleanliness and responsiveness. Blended with higher viscosity and lower volatility than conventional oils, this oil reduces oil consumption due to burn-off, while the special seal conditioning agent helps minimize leaks from worn or stiff seals. By actively keeping high mileage engines clean, it extends engine life, conditions seals, prevents leaks and oil burn-off, provides enhanced protection for worn engine parts, and helps reduce oil consumption.
