Oil Change Interval:
Typically every 7,500 to 10,000 miles (12,000-16,000 km) or annually, whichever comes first. Check manual for specific interval and oil type.
Transmission Fluid Interval:
Often recommended around 30,000 to 60,000 miles (48,000-96,000 km) for automatic transmission fluid and filter change. Consult the manual for the precise interval.
Engine Oil Spec:
MB 229.1 or MB 229.3 specification synthetic oil, typically 0W-40 or 5W-40. Always verify with the manual.
Coolant Spec:
Mercedes-Benz approved coolant (e.g., G48 or similar silicate-free organic acid technology - OAT), mixed 50/50 with distilled water.
Brake Fluid Spec:
DOT 4 or DOT 5.1 brake fluid. Ensure compliance with MB specifications.
Power Steering Fluid:
MB 236.3 specification power steering fluid or Pentosin CHF 11S. Verify specific requirement.
Known Issues:
Common issues can include biodegradable wiring harness insulation (requiring replacement), ABC hydraulic system leaks (though ABC was more prevalent in later R230 chassis), MAF sensor issues, catalytic converter failure, and vacuum hose deterioration. The V12 engine requires meticulous maintenance.
