The oil capacity of an 8.2L Detroit Diesel engine varies slightly depending on the specific model and configuration (e.g., whether it has an oil cooler). However, a good estimate for the
total oil capacity is between 12 and 15 quarts (approximately 11.4 and 14.2 liters).
To know the exact capacity for your specific engine, always consult your engine's owner's manual. This is crucial to avoid overfilling or underfilling, which can damage the engine.
