**Why Oil Matters**
Engine oil lubricates moving parts, reduces friction, and keeps your engine cool and clean. Regular oil changes are the single most important maintenance task for longevity and reliability.

**Recommended Intervals**
Most modern Hyundais use Hyundai's Maintenance Minder system:
- **Every 10,000 miles or 12 months**, whichever comes first, for normal driving
- **Every 5,000-7,500 miles** if you drive in severe conditions (heavy traffic, extreme temperatures, towing, or frequent short trips)

Your owner's manual has your exact interval; our service team can confirm what's right for your vehicle.

**What Happens During an Oil Change**
1. Drain old oil
2. Replace the filter
3. Fill with genuine Hyundai oil and filter
4. Reset the maintenance light

**Using Genuine Parts**
Our Parts department stocks genuine Hyundai oil and filters designed specifically for your engine. We stand behind every service.

**Why Regular Changes?**
They prevent wear, extend engine life, and maintain your warranty coverage.

**Stay on Schedule**
