What is the life expectancy of a Buick v 6 engine?

The average lifespan of a well-maintained Buick V6 engine is between 150,000 to 200,000 miles. However, this can vary greatly depending on a variety of factors such as driving conditions, maintenance habits, and the specific model and year of the engine. Regular maintenance and repairs, such as oil changes, transmission fluid changes, and general tune-ups, can help extend the life of the engine. Additionally, avoiding aggressive driving or overloading the engine can also contribute to a longer lifespan.
