Oil Change Interval:
Typically every 7,500-10,000 miles (12,000-16,000 km) or annually, consult manual for specific year/engine.
Spark Plug Replacement:
Varies by plug type, often around 30,000 miles (48,000 km) for standard plugs, longer for platinum.
Timing Belt Replacement:
N/A (M10 and M20 engines use timing chains; S14 M3 engine uses a timing chain).
Engine Oil Type:
Castrol GTX 20W-50 or similar for M10/M20 (check manual for specific viscosity and API ratings based on climate and engine).
Coolant Type:
BMW blue coolant or a silicate-free antifreeze (e.g., G11 specification or equivalent), 50/50 mix with distilled water.
Brake Fluid Type:
DOT 3 or DOT 4 brake fluid (ensure it is dry and fresh).
Transmission Fluid Manual:
GL-4 gear oil, typically 75W-90 or 80W-90. Capacity varies by gearbox.
Transmission Fluid Automatic:
Dexron II or III (check specific ZF gearbox manual for precise type). Capacity varies.
Power Steering Fluid:
ATF (Automatic Transmission Fluid) or specific Pentosin CHF 11S for certain hydraulic systems.
Cooling System:
Plastic coolant expansion tanks can become brittle and crack; water pumps and thermostats are common replacement items.
Suspension Bushings:
Front control arm bushings, rear trailing arm bushings, and sway bar links are prone to wear, affecting handling.
