Any machine has moving parts, and that means friction, which means wear. Even the best-engineered vehicles like Buick SUVs and GMC trucks can wear out sooner than necessary if those parts aren't lubricated and maintained properly. But if your vehicle gets regular service with genuine, factory-authorized parts, those parts will last much longer. The same goes for non-moving parts like your battery. Regular service helps keep everything in top condition, which means you're safer on the road as well.
