What Is LIQUI MOLY Synthoil Energy 0W-40?

LIQUI MOLY Synthoil Energy 0W-40 is a fully synthetic, low-friction engine oil developed for year-round use in compatible petrol and diesel engines. Its formulation is designed to provide reliable lubrication, help keep engine components clean and maintain protection across a range of operating conditions.

The SAE 0W-40 viscosity grade combines cold-start flow characteristics with lubrication at operating temperature for engines specifically designed to use this grade. The oil is formulated to circulate rapidly during cold starts, help control deposits and maintain reliable lubrication under demanding driving conditions.

Key Features and Benefits

• Fully synthetic formulation: Designed for dependable lubrication and performance in compatible engines.
• Cold-start protection: Supports rapid oil circulation after starting in suitable conditions.
• Engine cleanliness: Helps prevent troublesome deposits and supports clean engine operation.
• Wear protection: Helps protect moving engine components against wear.
• High-temperature stability: Designed to maintain lubrication performance at elevated operating temperatures.
• Low evaporation loss: Helps limit oil loss through evaporation.
• Lubrication reliability: Supports stable lubrication under varying operating conditions.
• Turbocharger compatibility: Tested for use in compatible turbocharged engines.
• Catalytic converter compatibility: Tested for use in suitable applications with catalytic converters.
• All-season performance: Suitable for year-round use where SAE 0W-40 is specified.

Actual engine performance, oil consumption and service intervals depend on the vehicle, operating conditions and manufacturer recommendations.

Vehicle make alone does not guarantee compatibility. Check the owner’s manual, engine code, model year and required oil specification before purchasing. For diesel engines fitted with a diesel particulate filter (DPF), verify compatibility with the vehicle manufacturer before use.

Available Pack Sizes

Choose the pack size according to your engine’s oil capacity and maintenance requirements:

• 1 Litre: Article No. 20701
• 4 Litres: Article No. 21101
• 5 Litres: Article No. 20990

Other regional packaging versions may use article numbers 9514 (1L), 2451 (4L) and 9515 (5L). Match the article number to the actual packaging being supplied.

Application Instructions

Use this engine oil only when SAE 0W-40 and the required specifications are permitted by the vehicle manufacturer. Follow the specified oil capacity and service interval in the owner’s manual or maintenance documentation.

Do not choose engine oil based on viscosity alone. Correct specification matching is essential for engine lubrication and emissions-system compatibility.
