Purpose and Specifications

Valvoline MaxLife 15W-40 is a high-mileage engine oil specifically formulated for vehicles with over 75,000 miles on the odometer. This synthetic blend oil is designed to revitalize aging engines by addressing common wear issues that develop as engines accumulate mileage.

The 15W-40 viscosity rating means the oil flows easily in cold temperatures (winter rating of 15) while maintaining a protective film at normal operating temperatures (summer rating of 40). This makes it suitable for year-round driving in most climates.

Key Benefits for High-Mileage Engines

• Reduces oil leaks and consumption: Contains seal enhancers that help prevent internal and external leaks common in older engines
• Fights four major wear signs: Addresses reduced power, fuel economy loss, oil leaks, and increased oil consumption
• Superior wear protection: Delivers 50% better wear protection compared to industry standards
• Better sludge defense: Provides 20% better sludge and deposit control to keep engine internals clean
• Enhanced heat protection: Offers 2.5 times better heat protection than standard oils, keeping engines cooler under stress
• Extended drain intervals: Allows you to follow manufacturer-recommended oil change schedules without compromising protection

When to Use / Replace?

Recommended for: Vehicles with 75,000+ miles that show signs of aging, including power loss, increased oil consumption, or visible leaks.

Oil change intervals: Follow your vehicle manufacturer's recommended oil change schedule, typically every 5,000 to 10,000 miles or every 3 to 6 months, whichever comes first. Valvoline MaxLife supports extended intervals when your engine manufacturer permits.

Operating temperature range: Performs reliably between -20°C (cold starts) and 100°C (normal engine operating temperature).

Shelf life: Unopened containers maintain quality for approximately 5 years when stored in cool, dry conditions away from direct sunlight.

Frequently Asked Questions

Q: Can I use MaxLife in a newer vehicle?
A: Yes. While formulated for high-mileage engines, MaxLife is safe for use in vehicles of any age. However, newer vehicles with lower mileage may benefit more from conventional or full synthetic oils matched to their specific requirements.

Q: Will this oil stop my engine leaks?
A: MaxLife contains seal enhancers that help reduce oil leaks by conditioning engine seals, but it cannot repair severely damaged seals. Minor seepage may improve, but major leaks require mechanical repair.

Q: Is this a full synthetic oil?
A: No. MaxLife is a synthetic blend, combining conventional and synthetic base oils with special additives. This provides better protection than conventional oil at a lower cost than full synthetic.
