Factors affecting engine lifespan include:
* Maintenance: Regular oil changes, timely repairs, and adherence to the manufacturer's recommended service schedule are crucial. Neglecting maintenance significantly shortens engine life.
* Driving habits: Aggressive driving, frequent hard acceleration, and towing heavy loads put extra stress on the engine, reducing its lifespan. Gentle driving extends its life.
* Environmental conditions: Extreme temperatures, dusty conditions, and salty air can accelerate wear and tear.
* Quality of fuel and fluids: Using low-quality fuel or fluids can damage engine components over time.
In short, while a Corolla engine is known for its reliability and longevity, its actual lifespan is determined by how well it's maintained and used.
