ZF LifeguardFluid 8 - Premium Automatic Transmission Fluid (20L)

Purpose and Specifications

ZF LifeguardFluid 8 is a semi-synthetic automatic transmission fluid engineered specifically for ZF 8HP automatic transmissions and select 6HP models. This fluid maintains consistent friction behavior throughout its service life, ensuring smooth gear shifts and vibration-free operation while protecting all internal transmission components.

Key Performance Features:

• Optimized viscosity reduces fuel consumption and improves engine efficiency
• Works reliably in extreme temperatures—from -42°C in cold climates to over 100°C under heavy driving
• Semi-synthetic base oil provides superior thermal stability, keeping the fluid effective across the entire service life of your transmission
• Custom additives protect gears, bearings, and seals from wear and corrosion
• Green color for easy identification and monitoring

When to Use / Replace?

Use ZF LifeguardFluid 8 exclusively in ZF 8HP and compatible 6HP automatic transmissions. Always follow your vehicle manufacturer's service schedule for fluid changes—typically every 60,000–100,000 km or as specified in your owner's manual. Never mix this fluid with other transmission oils; always perform a complete fluid change using only approved ZF LifeguardFluid 8 to maintain warranty coverage and transmission performance.

Technical Highlights:

• Density: 846 kg/m³ at 15°C
• Operating range: -42°C to 206°C (flash point)
• Flat viscosity-temperature curve ensures consistent performance in cold winters and hot summers
• 20-liter canister—ideal for professional service centers and fleet maintenance
