Kia K5
Data verified by Nick Marchenko, PhD
The 2021–2022 Kia K5 offers two engine options, each requiring specific oil maintenance to ensure optimal performance. The G4FP 1.6L I-4 engine utilizes 5.1 quarts of 0W-20 viscosity oil, while the more powerful G4KP 2.5L I-4 engine requires 6.1 quarts of 0W-30 viscosity oil. Regular oil changes are crucial for maintaining engine health and efficiency.
In addition to engine oil, it's important to monitor coolant levels. The G4FP engine has a coolant capacity of 4 quarts, while the G4KP engine holds 9.3 quarts. Keeping these fluids at the appropriate levels helps prevent overheating and ensures that your Kia K5 runs smoothly for years to come.

What type of oil does the Kia K5 use?
The 2021–2022 Kia K5 requires different oil types depending on the engine. The G4FP 1.6L I-4 engine uses 0W-20 oil, while the G4KP 2.5L I-4 engine requires 0W-30 oil.
How many quarts of oil does the Kia K5 take?
The oil capacity for the Kia K5 varies by engine. The G4FP 1.6L I-4 engine takes 5.1 quarts, while the G4KP 2.5L I-4 engine requires 6.1 quarts.
How often should I change oil in a Kia K5?
It is generally recommended to change the oil in your Kia K5 every 5,000 to 7,500 miles, depending on driving conditions and oil type. Always refer to your owner's manual for specific guidelines.
What is the coolant capacity of the Kia K5?
The coolant capacity for the Kia K5 varies by engine. The G4FP 1.6L I-4 engine has a coolant capacity of 4 quarts, while the G4KP 2.5L I-4 engine holds 9.3 quarts.
Does the Kia K5 need synthetic oil?
While synthetic oil is not mandatory, it is recommended for the Kia K5, especially for the G4KP 2.5L I-4 engine, as it provides better protection and performance under varying conditions.
What happens if I use the wrong oil viscosity in my Kia K5?
Using the wrong oil viscosity can lead to inadequate lubrication, increased engine wear, and potential engine damage. It's crucial to use the recommended viscosity for your specific engine.
What is an oil life monitor and how does it work?
An oil life monitor is a system that tracks engine operating conditions to determine when an oil change is necessary. It takes into account factors like mileage, engine temperature, and driving habits.
Can I mix synthetic and conventional oil?
While it is technically possible to mix synthetic and conventional oil, it is not recommended. Mixing can reduce the effectiveness of the oil and may lead to performance issues.
How do I know if my Kia K5 has an oil leak?
Signs of an oil leak include visible oil spots under the vehicle, a decrease in oil levels, or an oil warning light on the dashboard. Regularly checking your oil level can help identify leaks early.
What causes excessive oil consumption?
Excessive oil consumption can be caused by worn engine components, such as piston rings or valve seals, or by using the wrong oil viscosity. Regular maintenance can help mitigate these issues.
Should I check my oil when the engine is hot or cold?
It's best to check your oil when the engine is warm but not hot. This allows the oil to circulate and provide a more accurate reading on the dipstick.
What is the difference between an oil change and a flush?
An oil change involves draining the old oil and replacing it with new oil, while an oil flush is a process that cleans the engine by removing sludge and deposits before the oil change. Flushing is typically not necessary for routine maintenance.
