Purpose and Specifications

LIQUI MOLY Longtime High Tech 5W-30 is a premium fully synthetic engine oil designed for modern gasoline and diesel engines, including those with turbochargers, direct injection, and emission systems like DPF and catalytic converters. Its 5W-30 viscosity flows easily at cold starts down to -30°C for instant protection, while staying thick up to 150°C to shield against wear during high-heat highway driving or towing.

This low-SAPS formula meets tough specs like ACEA C3, API SN, BMW LL-04, MB 229.51, VW 505.01, and Ford WSS-M2C917-A, making it perfect for extended drain intervals up to 30,000 km or 24 months in approved vehicles. It cuts friction for smoother running, better fuel economy, and cleaner internals by reducing sludge and deposits.

• Excellent wear protection extends engine life under heavy loads
• Smooth operation with turbo and multi-valve tech
• Low emissions safe for catalytic converters and DPF
• High stability resists breakdown over long use

When to Use / Replace?

Use in vehicles specifying 5W-30 low-SAPS oils for long-life service, like BMW, Mercedes, VW, Ford, and Fiat models. Ideal for mixed city/highway driving, towing, or extreme temps from -30°C to 150°C. Replace every 15,000-30,000 km or 12-24 months based on your owner's manual, or sooner if towing heavy loads frequently. Shelf life is 5 years unopened.
