Valvoline 5W-40 SynPower Full Synthetic Motor Oil — 1qt Case of 6, European OEM Specs, Engine Protection

Valvoline VV966-CS 5W-40 SynPower is a full synthetic engine oil formulated to protect and clean modern European gasoline and diesel engines under everyday and demanding driving conditions.

Designed for premium European vehicles, this 5W-40 full synthetic oil blends high-quality base stocks with targeted additives to resist breakdown, control deposits, and reduce wear. It meets a broad set of OEM specifications so it suits many Audi, BMW, Mercedes-Benz, Porsche, Volkswagen and other European models. Supplied in a six-quart case, this formulation aims to provide consistent performance across temperature extremes and stop-and-go driving patterns.

How does this oil help protect my engine during city driving?

Stop-and-go traffic and short trips create more stress from frequent thermal cycling and low-speed contamination. Valvoline’s antioxidants and detergents work together to limit oxidation and dissolve sludge before it accumulates, helping maintain oil flow and component protection in congested driving.

• Detergents reduce deposit buildup on pistons and rings
• Antioxidants slow oil breakdown from repeated heat cycles
• 5W cold-start rating preserves flow during short, cool trips
• Full synthetic base offers stable viscosity under idling and stop-start conditions

Will this meet my carmaker’s European specifications?

VV966-CS is engineered to satisfy a wide range of manufacturer requirements common to European makes, covering both gasoline and diesel applications. Refer to your owner’s manual and the oil label to confirm compatibility with your vehicle’s required approvals.

• Complies with ACEA A3/B3 and A3/B4 performance levels
• Meets Mercedes-Benz MB 229.5, 229.3 and 226.5 specs
• Approved for VW 502.00/505.00/505.01, BMW LL-01 and LL-14FE+
• Porsche A40, Renault RN0700/RN0710 and more listed on the bottle

What advantages does 5W-40 full synthetic oil offer over conventional oils?

Full synthetic oils are engineered molecules that maintain protective film strength across wider temperature ranges and resist viscosity changes. That consistency improves engine protection, can reduce wear under high loads, and often supports better fuel economy compared with conventional oils.

• Stable viscosity at high operating temperatures (40 rating) for sustained protection
• Improved cold-flow (5W) for faster lubrication at startup
• Enhanced oxidation resistance extends oil life under heat and stress
• Formulated detergents keep internal parts cleaner than many conventional blends

How should I use and store this product for best results?

Change intervals and oil weight depend on your vehicle and driving habits; always follow your manufacturer’s service recommendations. Store sealed quarts upright in a cool, dry place away from direct sunlight and extreme temperatures to preserve additive effectiveness.

• Check owner’s manual for recommended oil type and change interval
• Replace oil filter at each oil change for maximum cleanliness
• Keep unused quarts sealed and stored between 40–80°F (4–27°C)
• Recycle used oil responsibly at approved collection centers

Who is this for? Valvoline VV966-CS 5W-40 SynPower is aimed at owners of modern European cars who want a reliable, high-performance synthetic oil that matches OEM-level approvals. It’s appropriate for drivers who encounter a mix of motorway and urban driving, owners of both gasoline and diesel models that require these specifications, and anyone seeking full synthetic protection in a convenient six-quart supply for multiple service jobs.
