Highlighted rows are major service milestones. Intervals vary with engine load, passenger/cargo weight, and driving conditions — severe use shortens them. The Carnival’s real-world cadence runs slightly different from this 7,500-mile grid in places: oil & filter is roughly every 8,000 miles/12 months (not 7,500); cabin air filter follows a roughly 24-month replacement cycle (about every 24,000 miles); engine air filter follows a roughly 36-month cycle (about every 36,000 miles); brake fluid exchange is every 48,000 miles/48 months; spark plugs on the naturally aspirated 3.5L V6 run a long 96,000-mile interval; and engine coolant is first at 120,000 miles/120 months, then every 24,000 miles after. Always confirm against your Owner’s Manual or with a Dean McCrary Kia technician.

Every 8,000 Miles

  • Engine oil & filter change (full synthetic 5W-30, 3.5L V6)
  • Tire rotation & balance
  • Multi-point inspection
  • Fluid top-off & leak check
  • Battery & brake condition check

Major Milestones

  • ~22.5k — Cabin air filter (~24 mo cycle)
  • ~37.5k — Engine air filter (~36 mo cycle)
  • 48k — Brake fluid exchange
  • 96k — Spark plugs (3.5L V6)
  • 120k — Engine coolant (then every 24k)

Tips for Longevity

  • Use genuine Kia parts and approved fluids
  • Rotate tires at every oil change
  • Inspect brakes before long road trips or heavy passenger loads
  • Stay on schedule — it keeps Warranty Forever active
  • Check for open recalls at every visit

2023 Carnival Maintenance FAQs

How Often Should I Change the Oil on a 2023 Kia Carnival?⌄

Kia recommends changing the 2023 Carnival’s oil and filter every 8,000 miles or 12 months under normal conditions, using full synthetic oil for the 3.5L V6. Severe use — frequent towing, short trips, dusty roads, or extended idling — shortens the interval; many severe-duty drivers change closer to every 4,000–5,000 miles.

Does the 2023 Kia Carnival Require Synthetic Oil?⌄

Kia recommends full synthetic SAE 5W-30 for the Carnival’s 3.5L GDI V6. Synthetic protects the direct-injection system and holds up far better in Gulf Coast heat, especially with a full load of passengers and cargo.

When Should I Replace the Spark Plugs on a 2023 Carnival?⌄

The naturally aspirated 3.5L V6 uses a long spark-plug interval of 96,000 miles under normal conditions — much longer than a turbocharged engine like the Carnival Hybrid’s 1.6T. Heavy loads or sustained high-RPM driving can justify earlier inspection.

Does Following This Schedule Protect My Warranty Forever Coverage?⌄

Yes. Warranty Forever stays active as long as you complete factory-recommended maintenance on time and keep records. Service with us and we document every visit automatically.
