Pennzoil High Mileage Full Synthetic 0W-20 Motor Oil is specifically created for engines with 75,000 miles or more. It is designed with seal swell technology to reduce oil consumption in high-mileage vehicles. Seal conditioners help rejuvenate old, dry seals. Formulated to provide all the same benefits as our Pennzoil Full Synthetic motor oil, it offers better engine protection* and is backed by a 10,000-mile protection guarantee** to help you go farther between oil changes(see Warranty Information below). Pennzoil High Mileage Full Synthetic is formulated for longer drain intervals than conventional and synthetic blend motor oils, provides enhanced wear protection in high and low temperatures, excellent resistance to oil breakdown in severe environments, and helps prevent sludge and deposit build-up. It provides the same engine protection as a 5W-20 and is suitable for use in vehicles currently using SAE 5W-20.
