* Model Year and Engine Type: Different Cadillac engines have different designs and inherent strengths and weaknesses. Older engines might be simpler but less refined, while newer engines might be more complex but potentially more durable (or prone to more sophisticated failures). Specific engine codes matter a great deal.
* Maintenance: Regular and proper maintenance is crucial. Following the manufacturer's recommended service schedule (oil changes, fluid flushes, etc.) dramatically extends engine life. Neglecting maintenance drastically shortens it.
* Driving Habits: Aggressive driving, frequent hard acceleration, and towing heavy loads put more stress on the engine and reduce its lifespan. Gentle driving extends engine life.
* Operating Conditions: Extreme temperatures (both hot and cold) can impact engine longevity. Driving in dusty or dirty conditions can also lead to premature wear.
* Quality of Parts Used in Repairs: Using inferior aftermarket parts during repairs can negatively affect the engine's reliability and lifespan.
Generally speaking, with proper maintenance and moderate driving habits, a Cadillac engine can last anywhere from 150,000 to 250,000 miles or more. However, it's not uncommon to see some engines reach 300,000 miles or even beyond. Conversely, neglecting maintenance can lead to engine failure well before 100,000 miles.
To get a more precise estimate, you'd need to specify the exact Cadillac model, year, and engine type. Even then, it's still an estimate based on averages; individual experiences can vary significantly.
