Infiniti Q70
Data verified by Nick Marchenko, PhD
Maintaining your Infiniti Q70 is essential for optimal performance, especially when it comes to engine oil and coolant. The 2014–2019 Infiniti Q70 offers three engine options: the VK56VD 5.6L V-8, the VQ35HR 3.5L V-6, and the VQ37VHR 3.7L V-6. Each engine has specific oil capacities and viscosities; for instance, the VK56VD requires 6.4 quarts of 5W-30 oil, while both VQ35HR and VQ37VHR engines need 5.2 quarts of the same viscosity.
In addition to oil, it's crucial to monitor coolant levels. The VK56VD engine has a coolant capacity of 11.5 quarts, while the VQ35HR and VQ37VHR engines have capacities of 9.1 and 9.5 quarts, respectively. Regular oil changes and coolant checks will help ensure that your Infiniti Q70 runs smoothly and efficiently throughout its lifespan.

What type of oil does the Infiniti Q70 use?
The Infiniti Q70 uses 5W-30 viscosity oil for all its engine options, including the VK56VD V-8 and the VQ35HR and VQ37VHR V-6 engines.
How many quarts of oil does the Infiniti Q70 take?
The oil capacity for the Infiniti Q70 varies by engine: the VK56VD V-8 requires 6.4 quarts, while both the VQ35HR and VQ37VHR V-6 engines require 5.2 quarts.
How often should I change oil in a Infiniti Q70?
It's generally recommended to change the oil in your Infiniti Q70 every 5,000 to 7,500 miles, depending on driving conditions and oil type used.
What is the coolant capacity of the Infiniti Q70?
The coolant capacity for the Infiniti Q70 varies by engine: the VK56VD has an 11.5-quart capacity, while the VQ35HR and VQ37VHR have capacities of 9.1 and 9.5 quarts, respectively.
Does the Infiniti Q70 need synthetic oil?
While synthetic oil is not mandatory, it is recommended for the Infiniti Q70 as it provides better protection and performance, especially in extreme temperatures.
What happens if I use the wrong oil viscosity in my Infiniti Q70?
Using the wrong oil viscosity can lead to inadequate lubrication, increased engine wear, and potentially severe engine damage. Always use the recommended 5W-30 viscosity.
What is an oil life monitor and how does it work?
An oil life monitor tracks the condition of your engine oil based on driving habits and conditions. It alerts you when it's time for an oil change, helping to maintain engine health.
Can I mix synthetic and conventional oil?
While it's technically possible to mix synthetic and conventional oil, it's not recommended. Mixing can reduce the effectiveness of the oil and compromise engine protection.
How do I know if my Infiniti Q70 has an oil leak?
Signs of an oil leak in your Infiniti Q70 include oil spots under the vehicle, a burning oil smell, or a drop in oil levels between changes. Regular checks can help identify leaks early.
What causes excessive oil consumption?
Excessive oil consumption can be caused by worn piston rings, valve seals, or gaskets. It's important to diagnose the issue promptly to prevent engine damage.
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 for a more accurate reading, as the oil will have circulated and settled.
What is the difference between an oil change and a flush?
An oil change involves draining old oil and replacing it with new oil, while an oil flush uses a cleaning solution to remove sludge and contaminants from the engine before adding new oil.
