Pennzoil High Mileage 5W-30 Synthetic Blend motor oil is designed for engines with more than 120,000 kilometers, specially formulated to help stop leaks from seals and reduce the oil consumption that is typical of older, worn engines. Severe oil consumption and oil burn-off may also cause other issues, leaving deposits on the internal parts of your engine. Pennzoil High Mileage motor oil also helps prevent dirt and sludge from turning into performance-robbing deposits. Pennzoil High Mileage motor oil comes with a warranty coverage of up to 10 years or 400,000 kilometers*, whichever comes first (see Warranty Information below).
