Purpose and Specifications

ZF LifeguardFluid 8 (S671.090.312) is the genuine automatic transmission fluid designed specifically for ZF 8HP transmissions in premium vehicles like BMW, Audi, VW, and Porsche. This 1-liter green bottle delivers smooth shifting, reduces vibrations, and protects components for longer life.

It flows easily in extreme cold down to -42°C for quick starts in winter and stays stable up to 206°C in hot conditions, saving fuel while handling daily drives or heavy towing. Semi-synthetic formula fights heat and oxidation, keeping your transmission clean and efficient over tens of thousands of kilometers.

When to Use / Replace?

Use this fluid only in ZF 6HP and 8HP transmissions requiring Lifeguard 8 spec, such as BMW 3 Series (F30/F31), Audi A6/A8, or VW models with G060162A2. Replace every 60,000 to 100,000 km or 4-5 years, whichever comes first, during service to prevent slipping or harsh shifts. Shake vigorously for 15 seconds before pouring.

Shelf life is 5 years unopened in cool, dry storage.
