150,000 miles: oil & filter change, tire rotation, and multi-point inspection wrap up the chart.

Rows shaded above mark the major milestones. How hard you drive — engine load, passenger and cargo weight, road conditions — can shift these intervals, and severe use calls for more frequent visits. The Carnival’s real-world rhythm departs from this 7,500-mile grid in a few spots: oil & filter really runs closer to every 8,000 miles/12 months; the cabin air filter follows roughly a 24-month cycle (about every 24,000 miles); the engine air filter follows roughly a 36-month cycle (about every 36,000 miles); brake fluid gets exchanged every 48,000 miles/48 months; spark plugs on the naturally aspirated 3.5L V6 stretch to a long 96,000 miles; and engine coolant is first flushed at 120,000 miles/120 months, then every 24,000 miles after. When in doubt, check your Owner’s Manual or ask a Dean McCrary Kia technician.

Every 8,000 Miles

  • Full synthetic 5W-30 oil & filter change (3.5L V6)
  • Tire rotation and balance
  • Multi-point vehicle inspection
  • Top off fluids and check for leaks
  • Check battery and brake condition

Key Mileage Markers

  • ~22.5k mi — cabin air filter (~24 mo cycle)
  • ~37.5k mi — engine air filter (~36 mo cycle)
  • 48k mi — brake fluid exchange
  • 96k mi — spark plugs (3.5L V6)
  • 120k mi — first coolant flush, then every 24k

2023 Carnival Service Questions

How Often Does a 2023 Kia Carnival Need an Oil Change?⌄

Under normal driving, Kia calls for a full-synthetic oil and filter change every 8,000 miles or 12 months on the 2023 Carnival's 3.5L V6. Conditions like frequent towing, short trips, dusty roads, or lots of idling count as severe use and shorten that window — many drivers in that category are better off every 4,000–5,000 miles.

Is Synthetic Oil Required for the 2023 Kia Carnival?⌄

Yes — Kia specifies full synthetic SAE 5W-30 for the Carnival’s 3.5L GDI V6. It protects the direct-injection system and stands up well to hot, humid Pine Belt summers, especially when the van’s loaded with passengers and cargo.

When Do the Spark Plugs Need Replacing on a 2023 Carnival?⌄

The naturally aspirated 3.5L V6 stretches to a long 96,000-mile spark-plug interval under normal use — well beyond a turbocharged engine like the Carnival Hybrid’s 1.6T. Heavy loads or sustained high-RPM driving is reason enough for an earlier look.

Does Staying on This Schedule Protect My Factory Warranty Coverage?⌄

It does. factory warranty remains active as long as factory-recommended maintenance gets done on time and documented. Service with our team and that record-keeping happens automatically.
