75,000 miles is more than a mile marker. It’s a signal that your engine is ready for greater protection. That’s when you need Valvoline High Mileage with MaxLife Technology Motor Oil. Its exclusive formula is proven to maximize engine life in cars, trucks, and SUVs with over 75,000 miles. Our mixture is specially developed with a unique combination of synthetic and premium conventional oils to protect your high-mileage motor against wear, friction, heat, and deposits – the four major causes of engine breakdown and expensive repairs.
