The engine is the heart of every vehicle. Its reliability directly affects a car's lifespan, maintenance costs, and overall driving experience. While some engines require major repairs after only 150,000–200,000 kilometers, others can easily exceed 500,000–700,000 kilometers when properly maintained. Choosing a vehicle with a proven engine can save owners significant time and money over the years.
Regardless of the engine type, replacing worn auto parts on schedule and following the manufacturer's maintenance recommendations are the best ways to maximize engine life.
