Pennzoil High Mileage vehicle motor oil is specially formulated for engines with over 75,000 miles. Engines with over 75,000 miles of driving begin to show their age. Exceeding industry standards in preventing oil consumption, Pennzoil High Mileage Vehicle oil is designed to give extra life protection to engines with high miles. High mileage engines tend to consume oil, are prone to leaks, and can lose their power. This oil’s special formulation reduces excessive oil loss, slows down and prevents leaks altogether, and helps older engines regain lost power by improving cylinder compression and providing extra protection for worn engine parts.
