* Maintenance: Regular oil changes, proper fluid levels, and timely repairs are crucial. Neglecting maintenance will drastically shorten engine life.
* Driving habits: Aggressive driving (hard acceleration, frequent high RPMs) puts more stress on the engine and reduces its lifespan. Gentle driving extends its life.
* Environmental conditions: Extreme heat or cold can put extra strain on the engine.
* Previous repairs/history: Has the engine undergone any major repairs or experienced any significant damage?
Without knowing the maintenance history and driving habits of a *specific* 2000 Ford Windstar, it's impossible to give a definitive mileage estimate. However, with proper care, a well-maintained 2000 Windstar engine *could* potentially reach 200,000 miles or more. However, this is not guaranteed, and many engines will experience significant wear and tear or require major repairs before reaching that milestone. Many will fail well before 200,000 miles due to neglect or unforeseen issues. Consider 150,000 miles as a more realistic expectation for many, but again, this is variable depending on the factors mentioned above.
