The 2004 Infiniti G35 with the VQ35DE 3.5-liter V6 typically requires about 5.5 quarts (approximately 5.2 liters) of engine oil for a full change using a new filter.
The exact amount can vary slightly depending on whether you replace the oil filter and the presence of any accessories (such as an oil cooler). For the most accurate specification, consult the owner's manual or a dealership service bulletin. In practice, many DIYers fill to the full specification and then top off as needed after checking the dipstick.
Oil capacity and recommendations
Here is a concise breakdown of the capacity and related guidance for performing an oil change on the 2004 Infiniti G35.
- Oil capacity with filter: 5.5 quarts (5.2 liters).
- Oil capacity without filter: varies slightly; typically around 4.8–5.0 quarts depending on drainage and engine configuration.
- Recommended oil viscosity: 5W-30 synthetic is standard; 10W-30 may be used in hotter climates per manual guidance.
- Oil/filter quality: use a high-quality full-synthetic or synthetic-blend oil and an OEM/Nissan/Infiniti oil filter (or an equivalent).
When performing an oil change, start with the full capacity listed above and then top off to the correct level after a short idle and check. Variations in drain efficiency or filter size can affect the final amount you need to reach the proper dipstick level.
Oil change steps (quick guide)
If you’re doing the change yourself, follow these basic steps to ensure a proper fill and level.
- Warm the engine briefly, then park on a level surface and secure the vehicle.
- Place a drain pan under the engine and remove the drain plug to let the old oil drain out completely.
- Remove and replace the oil filter with a new one, applying a light coat of oil to the gasket.
- reinstall the drain plug securely after drainage is complete.
- Pour in 5.5 quarts of new oil (about 5.2 liters) to start, then start the engine and let it run for a minute to circulate.
- Turn off the engine, wait a few minutes, and check the oil level with the dipstick; add more oil in small increments if needed until the level is between the full and fill marks.
- Check for leaks around the drain plug and filter, then dispose of used oil properly.
Following these steps helps ensure the engine is properly lubricated and the oil level is accurate after the change.
Summary: For a 2004 Infiniti G35 with the VQ35DE engine, plan around 5.5 quarts of engine oil with a new filter for a full change, using 5W-30 synthetic as the default recommendation. Always verify with the owner's manual and adjust for any optional equipment or climate, then confirm the level with the dipstick after the oil has settled.
