What is the engine oil type and capacity for a 12V92?

The Detroit Diesel 12V92 engine requires API CF-4, CG-4, or CH-4 rated oil. The exact viscosity grade will depend on the operating temperature. Consult your engine's owner's manual for the specific viscosity recommendation based on ambient temperature. Common viscosities include 15W-40 and 20W-40.

The oil capacity is approximately 18 US gallons (68 litres). However, this is an *approximate* figure and the exact amount might vary slightly depending on the specific configuration of your engine and oil filter. Always refer to your engine's official documentation for the precise oil capacity. Overfilling or underfilling can both damage the engine.
