In short, the amount of oil a Q50 needs depends on the engine. The typical figures are roughly 5.2–5.5 quarts for the 3.7L V6, about 6.0 quarts for the 3.0L twin‑turbo, and around 5.5 quarts for the hybrid, with a new filter included. Always verify the exact specification for your VIN in the owner’s manual.
The Infiniti Q50 has evolved with several engine options across years and markets. This guide breaks down capacities by engine, explains how to fill to the correct level, and shows where to look up the precise numbers for your specific car. It also covers best practices to avoid overfill or underfill during oil changes.
Oil capacity by engine
Capacities below are typical values and assume a standard oil change with a new filter. Exact figures can vary by model year and region; always confirm with your manual or dealer.
3.7-liter V6 (VQ37VHR)
- Oil capacity: approximately 5.2–5.5 quarts (about 5.0–5.3 liters) with a new filter.
Note: If you’re replacing the filter, plan for the higher end of the range to ensure you reach the full level after a brief oil settle.
3.0-liter twin-turbo V6 (VR30DDTT)
- Oil capacity: approximately 6.0 quarts (about 5.7 liters) with a new filter.
Reasonable to expect around 6 quarts to account for oil trapped in the filter and engine passages after draining.
3.5L Hybrid (Q50 Hybrid)
- Oil capacity: approximately 5.5 quarts (about 5.2 liters) with a new filter.
Hybrid variants share the 3.5L V6 block, so the figure is close to the standard V6 estimate but always verify for your exact year and configuration.
These figures indicate typical oil amounts needed when performing a standard oil change with a filter replacement. Always verify exact capacity for your VIN and model year in the owner’s manual or through an Infiniti service adviser.
Filling and checking oil
These steps guide you through safely adding and verifying the oil level after a change.
- Park on level ground and wait 5–10 minutes for the oil to settle in the pan.
- With the engine off, pull the dipstick, wipe it clean, reinsert fully, then pull it again to check the level.
- If the level is below the minimum mark, add small amounts of oil (about 0.5 quart at a time), recheck, and repeat until the level sits within the range between the MIN and MAX marks.
- Avoid overfilling. Overfilling can increase pressure and cause engine issues.
- After adding oil, start the engine and let it reach normal operating temperature, then recheck the level and top up if necessary to stay between the marks.
- Dispose of used oil and the filter properly. Use a high-quality synthetic oil that meets Infiniti/Nissan specifications.
Bottom line: accuracy matters. Use the recommended oil specification for your model year, replace the filter, and verify the level with a clean dipstick after the engine has settled.
Summary
The Infiniti Q50’s oil capacity varies by engine: roughly 5.2–5.5 quarts for the 3.7L V6, about 6.0 quarts for the 3.0L twin‑turbo, and around 5.5 quarts for the 3.5L Hybrid. Always confirm the exact capacity for your exact model year and VIN in the owner’s manual, and follow proper fill procedures to ensure accurate leveling and engine protection.
