A quick reference for the typical capacities of the fluids in a passenger vehicle or light truck. These are ranges across common vehicles — use them for planning and shopping, and confirm exact amounts in your service manual.
| System | Typical capacity |
|---|---|
| Engine oil | 4 – 8 qt |
| Engine coolant | 8 – 16 qt (2 – 4 gal) |
| Automatic transmission (total) | 8 – 14 qt |
| Transmission (drain and fill) | 4 – 6 qt |
| Brake fluid (full system) | about 1 qt |
| Power steering | about 1 qt |
| Differential (each) | 1.5 – 3 qt |
| Transfer case | 1 – 2 qt |
| Fuel tank | 12 – 26 gal |
Transmission total versus drain-and-fill differ a lot — a service usually replaces only the drain-and-fill amount unless the torque converter is drained too.
See the Oil Capacity Chart and Coolant Mixture Chart.
