    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. Anti-wear additives defend critical engine components, advanced friction-fighting agents reduce heat and abrasion, added detergents clean the inside of your engine, and premium seal conditioners handle aging seals to prevent leaks. It fights sludge, corrosion and rust that can rob your engine of horsepower, fuel efficiency and longevity. From extreme temperatures and cold starts to stop-and-go traffic and frequent short trips, viscosity modifiers make sure the oil flows more easily, coats more completely, and resists thermal breakdown under even the most intense driving conditions. Its unique mixture curbs contaminants to keep high-mileage engines from burning and consuming oil that can foul spark plugs, creating higher emissions and causing your motor to run roughly.

    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. Anti-wear additives defend critical engine components, advanced friction-fighting agents reduce heat and abrasion, added detergents clean the inside of your engine, and premium seal conditioners handle aging seals to prevent leaks. It fights sludge, corrosion and rust that can rob your engine of horsepower, fuel efficiency and longevity. From extreme temperatures and cold starts to stop-and-go traffic and frequent short trips, viscosity modifiers make sure the oil flows more easily, coats more completely, and resists thermal breakdown under even the most intense driving conditions. Its unique mixture curbs contaminants to keep high-mileage engines from burning and consuming oil that can foul spark plugs, creating higher emissions and causing your motor to run roughly.
