ZF Maintenance Guidelines - ECOMAT
Oil Change Intervals
 | Mineral Based ATF ~ 18,000 miles. |
| Semi-Synthetic Base ~ 36,000 miles. |
| Synthetic Base ~ 50,000 miles. |
| Castrol Transynd ~ 50,000 - 75,000 miles.* |
| ZF Ecofluid ~ 50,000 - 75,000 miles.* |
| ZF Ecofluid A ~ 75,000 - 100,000 miles.* |
*? Oil drain interval for light duty/coach duty
cycle accompanied with oil analysis.
The previous one-time "break-in" oil drain & filter
change at 600 miles is no longer needed.
The Ecomat uses only one internal transmission
filter (about $25) that is changed with each oil drain. Bolt holes
to access this filter have steel reinforced threads. |
