Keeping your 2024 Kia Carnival running at its best starts with routine maintenance, and oil changes are at the heart of it. Whether you’re commuting daily or heading off on road trips, using the right oil and sticking to recommended maintenance schedules will ensure solid performance, fuel efficiency, and engine longevity. The 2024 Kia Carnival is powered by a responsive engine designed for reliability and versatility, and with proper care, it will deliver on all fronts.
Let’s explore the Carnival’s specifications and break down the essentials for choosing the right oil, determining its capacity, and scheduling timely oil changes.
2024 Kia Carnival: Engine and Performance Specs
The 2024 Kia Carnival features a 3.5-liter V6 engine paired with an 8-speed automatic transmission, offering both power and smooth handling. This engine delivers 290 horsepower and 262 lb-ft of torque, providing a strong mix of speed and strength for passengers and cargo alike. Whether you’re merging onto highways or tackling hilly terrain, the front-wheel-drive system ensures confident traction and control.
For an engine of this size and design, proper lubrication is critical. With its high-performance demands, the right choice of motor oil helps maintain efficiency, cooling, and protection over the long haul.
Oil Change Essentials: Key Factors to Focus On
A) Oil Type, Capacity, and Change Intervals
- Oil Type: Kia recommends the use of full synthetic 0W-20 motor oil for the best protection and efficiency. Synthetic oils work especially well for high-performance engines like the Carnival’s, offering improved resistance to heat and breakdown over time.
- Oil Capacity: The 3.5L V6 in the Carnival has an engine oil capacity of 6.1 quarts, including the oil filter. Always use the correct amount to protect internal components and sustain optimal performance.
- Change Interval: Following Kia’s guidelines, replace your oil approximately every 7,500 to 10,000 miles or every 12 months, whichever comes first. For the most precise way to track oil health, consider using oil analysis services. These tests provide clarity on oil condition and enable you to time changes more scientifically.
Consistency with these specifications not only prevents avoidable engine wear but also keeps your vehicle performing efficiently over time.
B) Synthetic vs. Conventional Oil: Which Is Right for You?
When comparing synthetic and conventional motor oils for your 2024 Kia Carnival, synthetic comes out ahead for modern vehicles like this one:
- Synthetic Oils: Made with uniform molecules, synthetic oils resist heat and cold temperatures better. They provide improved lubrication, reduce sludge, and offer longer intervals between changes. This is especially important in engines like the Carnival’s, which operate under demanding conditions.
- Conventional Oils: Often less costly, conventional oils may work for older vehicles with simpler engines. However, they break down faster, are prone to impurities, and require more frequent changes.
For your Kia Carnival, a synthetic oil like AMSOIL Signature Series 0W-20 is the smarter choice. It offers extended drain intervals, better protection, and efficiency gains tailored to modern engines.

To help you make an informed decision, here are two reliable options for your 2024 Kia Carnival:
- AMSOIL Signature Series 0W-20 100% Synthetic Motor Oil
