Oil and fluid changes are the heartbeat of vehicle maintenance. Fresh engine oil lubricates your engine, reduces wear, and keeps it running efficiently. Transmission fluid, coolant, brake fluid, and power steering fluid are equally important-each plays a vital role in different systems.

How often you need changes depends on your driving habits, vehicle age, and manufacturer recommendations (check your owner's manual). Modern engines and fluids have come a long way, but regular changes still matter for longevity.

At Castle Chevrolet McHenry, we use quality OEM fluids matched to your Chevrolet's specs. Our technicians check fluid levels during every visit and advise when a full change is due.
