Most 2007 Infiniti models require a full-synthetic 5W-30 engine oil. The exact grade and capacity depend on the engine and model, so always verify with the owner's manual or the under-hood specification label.
Model-specific oil recommendations
Below is a concise guide to the common oil specifications for the 2007 Infiniti lineup. It covers the main engines found in that year’s models (V6 in G35/M35/FX35 and V8 in FX45/QX56). For each model, synthetic 5W-30 is typically recommended.
- G35 (3.5L V6, VQ35DE): 5W-30 synthetic oil, API SN/ILSAC GF-5 or newer; check capacity in manual.
- M35 (3.5L V6, VQ35DE): 5W-30 synthetic oil, API SN/ILSAC GF-5 or newer.
- FX35 (3.5L V6, VQ35DE): 5W-30 synthetic oil, API SN/ILSAC GF-5 or newer.
- FX45 (4.5L V8, VK45DE): 5W-30 synthetic oil, API SN/ILSAC GF-5 or newer.
- QX56 (5.6L V8, VK56DE): 5W-30 synthetic oil, API SN/ILSAC GF-5 or newer.
Capacity varies by engine, generally around five quarts for the V6s and more for the V8s; always verify the exact amount in your owner’s manual or on the service label under the hood.
Climate considerations
In regions with extreme temperatures, Infiniti may recommend an alternate viscosity. Typical guidance for 2007 models is to use 5W-30 synthetic under normal conditions, with possible adjustments to 0W-30 or 10W-30 based on climate. Confirm the specification for your vehicle’s climate with the manual.
Always follow Infiniti's official guidance for oil type and change intervals, and use a high-quality API SN or ILSAC GF-5 or newer full-synthetic motor oil.
Summary
For 2007 Infiniti models, the prevailing recommendation is a full-synthetic 5W-30 motor oil, applicable to most G35, M35, FX35, FX45, and QX56 engines. Always cross-check the exact grade and capacity for your specific model and engine in the owner's manual or on the under-hood label, and use a certified oil that meets API SN/ILSAC GF-5 or newer.
