Purpose and Specifications

ZF LifeguardFluid CVT 1 (5961.308.626) is the genuine automatic transmission fluid designed specifically for CVT (continuously variable transmission) systems in vehicles from brands like BMW and General Motors. This 1-liter bottle of high-quality oil ensures smooth, stepless gear shifting by reducing friction and protecting belts and pulleys from wear.

It maintains peak performance in everyday driving conditions, handling operating temperatures from -30°C to over 120°C for reliable power transfer without slippage or overheating. The low-viscosity formula flows easily at cold starts and stays stable during hot commutes, extending transmission life up to 150,000 km or 8 years with proper maintenance.

• Capacity: 1 liter bottle, perfect for partial or full fluid changes
• Origin: Made in Germany for ZF-approved durability
• Shelf life: Up to 5 years unopened when stored cool and dry

When to Use / Replace?

Use this fluid exclusively for ZF CVT transmissions meeting CVT 1 specs to avoid damage from incompatible oils. Replace every 60,000-100,000 km or every 4-5 years, or sooner if you notice slipping gears, unusual noise, or shuddering during acceleration.

Ideal for routine service on compatible BMW and GM models; always check your owner's manual for exact intervals. Draining and refilling typically requires 4-7 liters total, so stock up for complete jobs.
