Purpose and Specifications

LIQUI MOLY Synthoil High Tech 5W-40 is a fully synthetic engine oil that delivers top protection for 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 ACEA A3/B4 and API SN standards, plus approvals like BMW Longlife-98, MB 229.3, Porsche A40, and VW 502 00/505 00. It keeps oil consumption low, ensures smooth running, and maintains peak performance even with long change intervals up to 40,000 km or 12 months, depending on your vehicle's manual.

• Instant cold-start protection prevents wear
• Outstanding engine cleanliness reduces sludge
• Low evaporation cuts top-offs
• Compatible with turbos and catalytic converters
• Mixes with other motor oils

When to Use / Replace?

Use in modern cars needing high-performance synthetic oil for all-season driving. Perfect for extended intervals if your manual allows up to 40,000 km (25,000 miles) or 12 months. Replace sooner in severe conditions like frequent short trips, towing, or dusty roads—aim for every 15,000-20,000 km or 6-9 months.

Shelf life is 5 years unopened when stored cool and dry. Check oil level monthly; top off if low.
