Most modern vehicles, including Cadillacs, benefit from an oil change every 7,500 to 10,000 miles or as recommended in your owner's manual-some newer models can go longer with synthetic oil. Regular oil changes keep your engine clean and running smoothly, preventing costly repairs down the road.

Your vehicle's specific interval depends on the engine type, driving habits, and whether you use synthetic or conventional oil. Castle Cadillac McHenry's Service team can review your owner's manual and recommend the best schedule for your car. We carry genuine OEM oil and filters, and our technicians know Cadillacs inside and out.
