Purpose and Specifications

LIQUI MOLY Synthoil High Tech 5W-40 is a fully synthetic engine oil that delivers top protection for modern gasoline and diesel engines, including those with turbochargers and multi-valve tech. Its 5W-40 viscosity flows easily at cold starts down to -30°C for quick lubrication, while staying thick up to 150°C to shield against wear during hard driving.

This premium oil meets strict specs like ACEA A3/B4, API SM, BMW Longlife-98, MB 229.3, Porsche A40, and VW 502.00/505.00, making it perfect for high-performance European cars. It cuts oil burn, keeps engines clean, ensures smooth running, and supports extended change intervals up to 15,000 km or 12 months under normal use.

• Instant cold-start protection prevents wear on startup
• Low evaporation means less top-offs between changes
• High shear stability for long engine life under heavy loads
• Proven safe for turbos and catalytic converters

Replace every 10,000-15,000 km or 12 months for daily drivers; cut to 7,500 km for severe conditions like towing or dusty roads. Shelf life is 5 years unopened in cool, dry storage.
