Oil changes are one of the most important things you can do to keep your Chevrolet running strong and lasting longer.

**Why it matters.** Engine oil lubricates moving parts, reduces friction, cools the engine, and removes contaminants. Over time, it breaks down and loses effectiveness. Fresh oil keeps everything running smoothly and prevents costly damage.

**Recommended intervals.** Check your owner's manual for your specific model-most modern Chevrolets run 7,500-10,000 miles between changes, though some synthetic oils can go longer. Your driving habits (city, highway, towing) and climate also play a role.

**What happens during service.** We drain the old oil, replace the filter, and refill with the correct OEM oil for your vehicle. We also perform a fluid check and brief inspection.

**Genuine OEM oil and filters.** We use authentic Chevrolet-approved products to ensure compatibility and performance.

**Easy scheduling.** Call (630) 279-5200 or book online. Quick service means you're back on the road fast.

**Smart reminder.** Keep your receipts or ask us to track your service history. We can remind you when the next change is due.

Regular oil changes extend your vehicle's life and reliability. Schedule yours today at Castle Chevrolet.
