Detailed Fluid Capacity Table
| System | Capacity | Recommended Fluid | Service Notes |
|---|---|---|---|
| Engine oil | 6.5 L (6.9 qt) | Full-synthetic engine oil | Capacity includes replacement of the oil filter. Add oil gradually and verify the final level using the dipstick. |
| Cooling system | Approx. 10.5 L (11.1 qt) | BMW-compatible phosphate- and nitrite-free coolant mixed 50/50 with distilled water | The amount required during normal service may be lower because some coolant remains inside the engine and heater core. |
| Manual transmission | Approx. 1.3 L (1.4 qt) | Fluid matching the transmission identification label | Vehicle should be level. Fill until fluid reaches the lower edge of the fill opening. |
| Automatic transmission | Approx. 3.0–4.0 L during a typical drain and refill | Approved ATF matching the transmission identification label | Total dry capacity is substantially higher. Final level must be checked using the correct temperature and filling procedure. |
| Rear differential | Approx. 1.7 L (1.8 qt) | 75W-90 GL-5 gear oil | M3 limited-slip differentials require a fluid suitable for clutch-type limited-slip differentials. |
| Power steering | Fill to the appropriate reservoir mark | Dexron-compatible ATF | Do not use ordinary power-steering fluid. Check the reservoir cap and label before adding fluid. |
| Brake system | Fill as required | DOT 4 brake fluid | Brake-fluid quantity varies during flushing and bleeding. Use only new fluid from a sealed container. |
| Clutch hydraulic system | Shares the brake-fluid reservoir | DOT 4 brake fluid | Manual-transmission models use the same reservoir as the brake system. |
| Fuel tank | 65 L (17.2 US gal) | Premium unleaded gasoline | Listed capacity is approximate. |
| Windshield washer system | Varies by equipment | Windshield washer fluid suitable for the climate | Reservoir capacity may differ on vehicles equipped with headlight washers. |
Important: Always verify the label on the transmission, power-steering reservoir, and other components before selecting a fluid. BMW used different suppliers and fluid specifications during E36 production.
