The 3.7-liter Infiniti V6 typically requires about 5.1 quarts of engine oil with the filter installed, with a common operating range of roughly 4.8 to 5.3 quarts depending on year and model.
What you should know about the 3.7L V6 oil capacity
The 3.7L V6 (often referred to by the engine code VQ37VHR) is used in several Infiniti models such as the G37 and Q60. Manufacturer guidance typically lists an oil capacity of around 5.1 quarts with the filter, though variations can occur due to differences in filter size or minor engineering changes over model years. Always verify the exact figure in your owner's manual or on the under-hood information sticker for your specific vehicle.
Below are the general figures and recommendations commonly associated with the 3.7L V6 across applicable Infiniti models.
- Oil capacity (with filter): about 5.1 quarts (roughly 4.8–5.3 quarts depending on year and filter choice).
- Recommended oil viscosity: typically 5W-30 synthetic for most climates; 0W-30 can be considered in very cold environments if specified in the manual.
- Oil type: full synthetic or high-quality synthetic blend as specified by Infiniti for your model and climate.
In short, plan for about five quarts on hand, and adjust based on your exact model year, filter, and any dealer-recommended specifications.
Step-by-step oil change guidance for a 3.7L Infiniti
If you’re performing an oil change yourself, use these general steps as a guide while referring to your owner’s manual for precise torque values and part numbers.
- Warm up the engine briefly to let the oil drain more easily, then park on a level surface and engage the parking brake.
- Raise the vehicle safely and support it with stands if needed, ensuring you have clear access to the oil pan.
- Place a drain pan beneath the oil pan, remove the drain plug, and allow the old oil to fully drain away.
- Remove the old oil filter, note its placement, and replace it with a new filter. Lubricate the gasket on the new filter with a bit of fresh oil.
- Reinstall the drain plug and snug it to the manufacturer’s specified torque, then pour in the recommended amount of oil (about 5.1 quarts as a starting point) using the correct viscosity.
- Check the oil level with the dipstick, adding small amounts of oil as needed until the level reaches the full mark.
- Start the engine and look for leaks, then recheck the level after a few minutes of idling and adjust if necessary. Reset any maintenance light if applicable.
Following these steps should set you up with a proper fill around the typical capacity of about 5.1 quarts; always confirm by checking the dipstick after the initial fill and run.
Summary
The Infiniti 3.7L V6 generally uses about 5.1 quarts of engine oil with a filter, with a typical range of 4.8–5.3 quarts depending on model year and filter. Use 5W-30 synthetic oil unless another grade is specified in your manual, and always verify exact capacity and procedure for your specific vehicle. Regularly check the dipstick after an oil change to ensure a correct level, and consult your owner’s manual or dealer for model-specific guidance.
