Purpose and Specifications

Valvoline MaxLife 5W-40 is a full synthetic high-mileage engine oil designed for vehicles with over 75,000 miles on the odometer. This premium oil fights four major causes of engine wear: friction, deposits, sludge, and oil leaks that commonly develop in aging engines.

The 5W-40 viscosity rating means the oil flows instantly at cold temperatures (down to -30°C) for easy winter starts, while maintaining a protective film at high operating temperatures up to 150°C. This oil meets strict European and Asian standards including ACEA A3/B3/B4, VW 502.00/505.00, MB 229.3, and Renault RN0700/RN0710 specifications, making it suitable for most gasoline and diesel engines including direct-injection models.

Key Benefits for High-Mileage Engines

• Reduces oil consumption: Special seal conditioners prevent leaks and oil burn-off in older engines
• Cleans engine internals: Extra detergents remove harmful sludge and carbon deposits that accumulate over time
• Protects against wear: Advanced anti-wear additives create a strong protective film on pistons, bearings, and valve train
• Better heat protection: Resists oil breakdown at high temperatures, extending oil life
• Cold-start performance: Flows instantly in winter conditions for immediate engine lubrication

When to Use / Replace?

Initial Use: Switch to MaxLife at 75,000+ miles or when your vehicle shows signs of reduced power, poor fuel economy, or visible oil leaks.

Replacement Interval: Follow your vehicle manufacturer's recommended oil change schedule, typically every 5,000-10,000 miles (8,000-16,000 km) or every 6-12 months, whichever comes first. MaxLife's long-drain formula supports extended intervals when approved by your vehicle's manual.

Storage: Keep unopened containers in a cool, dry place. Shelf life is typically 3-5 years from manufacture date when stored properly.
