Always check the required Porsche engine oil specification and viscosity for the individual model before ordering.  

Its advanced synthetic formulation helps reduce internal engine friction while maintaining a stable protective oil film under demanding driving conditions. The SAE 0W-40 viscosity combines excellent low-temperature flow characteristics with dependable lubrication at higher engine temperatures.

Suitable for selected petrol and diesel engines, including turbocharged applications, Synthoil Energy 0W-40 is an excellent choice for vehicles requiring its specified viscosity and performance standards.

What Does Synthoil Energy 0W-40 Do?

Engine oil lubricates moving components such as the crankshaft, camshafts, pistons and bearings, reducing friction and protecting internal surfaces against premature wear.

Synthoil Energy 0W-40 is formulated to circulate quickly following a cold start, helping protect critical engine components before the engine reaches its normal operating temperature.

Its fully synthetic base oils also provide excellent resistance to ageing, stable lubrication under load and protection against harmful deposits.

Why Choose Synthoil Energy 0W-40?

Its advanced formulation ensures rapid oil circulation during cold starts while maintaining a stable protective lubricating film at higher engine temperatures.

Particularly relevant for Porsche owners, Leichtlauf Energy 0W-40 carries official Porsche A40 approval, making it suitable for selected Porsche engines requiring this specification.

The two LIQUI MOLY product references contain the same Leichtlauf Energy 0W-40 formulation, with the difference being container size.

What Does Leichtlauf Energy 0W-40 Do?

Engine oil lubricates moving components such as the crankshaft, camshafts, pistons and bearings, reducing friction and protecting internal engine surfaces against premature wear.

Leichtlauf Energy 0W-40 is designed to circulate rapidly following a cold start, helping protect critical engine components before the engine reaches its normal operating temperature.

Its stable lubricating film also provides reliable protection under high engine loads, while the formulation helps prevent unwanted deposits and maintain engine cleanliness.

Why Choose Leichtlauf Energy 0W-40 for a Porsche?

The main advantage for applicable Porsche models is its official Porsche A40 approval.

Porsche A40 is a manufacturer oil specification used for selected Porsche petrol engines. Choosing an approved lubricant helps ensure the oil meets the required performance standards.

Leichtlauf Energy 0W-40 offers several benefits:

  • Excellent lubrication during cold starts
  • Reliable protection against engine wear
  • Stable lubrication at high operating temperatures
  • Reduced internal engine friction
  • Protection against sludge and deposits
  • Improved engine cleanliness
  • Good resistance to demanding operating conditions

Its SAE 0W-40 viscosity combines excellent low-temperature flow characteristics with dependable lubrication when the engine is warm.

Always confirm the required Porsche oil approval for the individual model and engine before use.

LIQUI MOLY also confirms that the oil has been tested for turbochargers and catalytic converters.

For Porsche applications, it should not automatically be substituted for oils requiring Porsche C20, C30, C40 or other manufacturer specifications.

Porsche A40 0W-40 Engine Oils & LIQUI MOLY Lubricants

Selecting the correct engine oil is essential for maintaining Porsche engine performance, reliability and protection against premature wear. The manufacturer's required oil approval is particularly important, as lubricants with the same viscosity may have different specifications and applications.

LIQUI MOLY Leichtlauf Energy 0W-40 carries official Porsche A40 approval, making it suitable for selected Porsche engines requiring this specification.

Its synthetic-technology formulation provides rapid lubrication during cold starts, excellent wear protection and stable oil performance under demanding operating conditions. The oil also helps prevent deposits, supporting engine cleanliness and long-term reliability.

Meeting ACEA A3/B4 and API SP specifications, Leichtlauf Energy 0W-40 is recommended by LIQUI MOLY for additional BMW, Mercedes-Benz, Renault and Volkswagen applications.

Available in 1-litre and 5-litre containers, it provides convenient options for topping up, routine oil changes and workshop servicing.
