Purpose and Specifications

Liqui Moly Top Tec 4100 5W-40 1L is a fully synthetic motor oil designed for modern gasoline and diesel engines, including those with turbochargers, catalytic converters, and alternative fuels like CNG or LPG. Its 5W-40 viscosity flows easily in cold starts down to -30°C for quick engine protection, while staying thick up to 150°C to shield against wear during high-heat operation.

This low-SAPS formula keeps your engine exceptionally clean, reduces oil and fuel consumption, and maintains steady oil pressure in all conditions. It's mixable with most engine oils and supports extended drain intervals up to 30,000 km or 24 months, per manufacturer guidelines.

• Exceptional wear protection for longer engine life
• High shear stability prevents breakdown under stress
• Ideal for turbocharged and direct-injection engines
