Purpose and Specifications

RAVENOL 1213102-B20-01-888 is a semi-synthetic transmission oil designed for ZF automatic transmissions in commercial vehicles like trucks and buses. This 20-liter bulk pack delivers maximum wear protection during all operating conditions, ensuring smooth gear shifts and reduced vibrations for better driving comfort.

It excels in high-heat environments, handling oil sump temperatures from 80°C to 110°C without breaking down, while providing reliable lubrication even in cold winter starts. The stable formula fights corrosion, foaming, and oxidation, keeping your transmission running cooler and longer.

• Oil change intervals: Up to 150,000 km or 3 years in buses; 2,000 hours or 2 years in trucks under normal use.
• Ideal operating temps: 175-220°C for peak performance—stays fluid below 240°C to avoid varnish and damage.
• Shelf life: Up to 5 years when stored properly in a cool, dry place.

When to Use / Replace?

Use RAVENOL ATF ZMS in ZF Ecomat transmissions for commercial fleets needing extended service life and cost savings. Perfect for heavy-duty applications like construction, fire trucks, or high-mileage routes where heat and stress are constant.

Replace every 150,000 km or 3 years in standard bus service, or sooner (1,500 hours/yearly) in demanding off-road or refuse collection work. Monitor temps—if over 240°C, change immediately to prevent seal hardening or slipping.

FAQ

Is this oil good for cold weather? Yes, it flows easily at low winter temperatures for quick protection and smooth shifts on startup.

Can I mix it with other ATFs? Compatible with ZF TE-ML 04D list fluids, but for best results, use full synthetic RAVENOL during changes.

What if my trans temp hits 250°C? Fluid life drops fast—expect varnish buildup; flush and replace to avoid costly repairs.
