Kia K900 Engine Oil Capacity: Complete Technical Guide & Calculator
This comprehensive guide provides exact engine oil specifications for the Kia K900 luxury sedan (2015-2020 models). Using our proprietary calculator and detailed technical data, you can ensure perfect oil change results every time. The Kia K900 represents the pinnacle of Korean luxury automotive engineering, and maintaining proper lubrication is critical for its high-performance engines.
Understanding Kia K900 Engine Specifications
The Kia K900 underwent a significant powertrain evolution during its production run in the United States. Understanding these engine differences is essential for proper maintenance and oil selection.
First Generation: 5.0L Tau V8 Engine (2015-2018)
The initial K900 models featured Hyundai-Kia’s renowned 5.0-liter “Tau” V8 engine. This naturally aspirated powerplant produces 420 horsepower at 6,000 RPM and 376 lb-ft of torque at 5,000 RPM. The engine utilizes a dual-overhead-cam (DOHC) design with 32 valves and features advanced technologies including:
- Direct fuel injection with 2,900 psi fuel pressure
- Dual continuously variable valve timing (CVVT)
- Aluminum block and head construction
- Variable intake manifold
- Dual-stage oil pump for efficiency
Second Generation: 3.3L Lambda II V6 Engine (2019-2020)
For the 2019 model refresh, Kia replaced the V8 with a more efficient but equally powerful 3.3-liter twin-turbocharged V6. This engine produces 365 horsepower at 6,000 RPM and 376 lb-ft of torque from just 1,300 RPM. Key technical features include:
- Twin-scroll turbochargers with electronic wastegates
- Integrated exhaust manifold
- High-pressure direct injection (up to 3,600 psi)
- Low-friction piston rings and bearings
- Advanced thermal management system
Oil Capacity Calculator & Technical Data
Our interactive calculator provides precise oil capacity based on your specific model year and engine type. The calculations account for oil filter capacity, oil cooler volume, and factory fill specifications.
Complete Technical Specifications Table
The following table provides comprehensive oil-related specifications for all Kia K900 models sold in the United States:
| Model Year | Engine | Oil Capacity (with filter) | Oil Type | Oil Filter Part # | Drain Plug Torque | Oil Change Interval |
|---|---|---|---|---|---|---|
| 2015-2018 | 5.0L Tau V8 | 7.0 quarts (6.6 liters) | API SN/SP 5W-30 | 26300-3L000 | 25-33 lb-ft | 7,500 miles |
| 2019-2020 | 3.3L Twin-Turbo V6 | 6.3 quarts (5.9 liters) | API SP 5W-30 | 26300-4S000 | 25-33 lb-ft | 6,000 miles* |
| *Reduced interval for turbocharged engines under severe conditions | ||||||
Oil Viscosity & Quality Standards
Modern Kia engines require specific oil formulations to maintain warranty coverage and ensure optimal performance. The following standards must be met:
API Certification Requirements
All Kia K900 models require oils meeting at minimum API SN or SP specifications. The SP standard, introduced in 2020, provides enhanced protection against:
- Low-speed pre-ignition (LSPI) in turbocharged engines
- Chain wear and timing system protection
- Enhanced deposit control
- Improved fuel economy retention
Viscosity Specifications
The 5W-30 viscosity grade is specifically engineered for the K900’s operating parameters:
Frequently Asked Questions
No, this is not recommended. While 5W-20 may flow more easily at cold temperatures, it does not provide adequate high-temperature protection for the K900’s high-performance engines. Using thinner oil than specified can lead to:
- Increased engine wear during high-load operation
- Potential oil consumption issues
- Reduced turbocharger bearing protection (2019-2020 models)
- Possible voiding of powertrain warranty
Always use the manufacturer-specified 5W-30 viscosity.
For vehicles driven less than 7,500 miles annually, Kia recommends following the 12-month interval, regardless of mileage. This is because:
- Oil additives degrade over time
- Condensation can accumulate in the oil system
- Acids form as combustion byproducts accumulate
- Modern low-viscosity oils have limited additive stability
For optimal engine protection, never exceed 12 months between oil changes, even with minimal driving.
The 5.0L V8 requires 0.7 quarts more oil than the 3.3L V6 (7.0 vs 6.3 quarts). This difference is due to several factors:
| Factor | 5.0L V8 | 3.3L V6 |
|---|---|---|
| Engine Displacement | 5.0 liters | 3.3 liters |
| Oil Gallery Volume | 0.4 liters larger | Standard volume |
| Oil Cooler Capacity | Larger dual cooler | Single integrated cooler |
| Oil Pan Design | Deep sump design | Shallow sump design |
Yes, absolutely. The K900 uses an advanced oil life monitoring system that tracks:
- Engine revolutions
- Operating temperatures
- Driving conditions
- Time since last reset
To reset the system:
- Turn ignition to ON (do not start engine)
- Press the “SETUP” button on the steering wheel
- Navigate to “Vehicle Settings”
- Select “Oil Life Reset”
- Press and hold the “OK” button for 3 seconds
Failure to reset will cause premature service reminders.
Oil Change Procedure & Best Practices
Recommended Tools & Materials
A proper oil change requires specific tools to ensure professional results:
- 14mm socket and ratchet for drain plug
- Oil filter wrench (76mm/14-flute for V8, 65mm for V6)
- Torque wrench (capable of 30 lb-ft)
- 6-7 quart drain pan with sealing lid
- Funnel with flexible neck
- Clean lint-free rags
- Safety glasses and nitrile gloves
Step-by-Step Procedure
Follow this sequence for optimal oil drainage and system protection:
- Run engine to normal operating temperature (10 minutes)
- Elevate vehicle on level surface with parking brake engaged
- Remove oil fill cap to break vacuum seal
- Place drain pan and remove drain plug (counterclockwise)
- Allow oil to drain for minimum 15 minutes
- Clean drain plug and replace sealing washer
- Torque drain plug to 29 lb-ft ±4 lb-ft
- Remove old filter and lubricate new filter gasket
- Install new filter hand-tight plus ¾ turn
- Add specified amount of oil (see calculator)
- Start engine and check for leaks
- Verify oil level after 5 minutes of operation
