Liqui Moly Longlife III - 5W30 - Fully Synthetic Engine Oil - ACEA C3 - API SN - 6L

It is primarily designed for Volkswagen Group vehicles (VW, Audi, Skoda, SEAT) that require specifications like VW 504 00 and VW 507 00. It is also suitable for many other gasoline and diesel engines, including those with DPFs, turbochargers, and catalytic converters, as well as vehicles running on CNG/LPG, provided they meet the specified ACEA C3, API SN, BMW Longlife-04, MB 229.51, or Porsche C30 standards.

For optimum effect and to maintain its specific properties, it is recommended to use this product unmixed. Mixing with other oils may dilute its performance characteristics.

Longlife III oils are formulated to provide extended protection, allowing for longer intervals between oil changes in vehicles equipped with variable service interval systems (like VW's WIV). They maintain their lubricating and protective qualities for extended periods.

This oil has a low-SAPS (Sulphated Ash, Phosphorus, Sulphur) formulation that complies with ACEA C3 and VW 507 00 standards. This means it produces fewer harmful combustion residues, preventing the clogging of the DPF and maximizing its service life.

While primarily designed for modern engines and long-life intervals, it is suitable for older vehicles that specifically require the ACEA C3, API SN, or VW 504 00/507 00 specifications. Always check your vehicle's manual.

Fully synthetic oils are engineered at a molecular level to provide superior lubrication, enhanced thermal stability, better flow at low temperatures, and increased resistance to breakdown under extreme conditions compared to conventional oils.

If your vehicle does not support extended oil change intervals, follow the manufacturer's standard service schedule for oil changes. This oil will still provide excellent protection during the recommended period.

Ensure the correct type and quantity of oil has been used. Check for any leaks. Reset the oil service indicator according to your vehicle's manual.

Verify that the correct oil specification for your vehicle is being used. Ensure oil changes are performed at recommended intervals. Check for other potential issues like tire pressure or air filter.

Confirm that the oil viscosity (5W30) and specification meet your vehicle's requirements. Older engines or those with specific wear may require a different oil formulation. Consult your mechanic.

While this oil is DPF-friendly, a warning light may indicate a blockage. Ensure the oil is suitable for DPFs (ACEA C3/VW 507 00). Follow your vehicle's procedure for DPF regeneration or consult a professional.
