Infiniti G35 Coupe Engine Oil Specs

The Infiniti G35 Coupe was produced from 2007 to 2007. This model typically uses 5W-30 full synthetic engine oil — a specification common to most Infiniti G35-series vehicles.

Selecting the correct oil viscosity for your Infiniti G35 Coupe is essential. Using a grade that is too thin reduces protection at operating temperature, while too thick an oil impairs cold-start flow and reduces fuel economy. Always match the exact grade shown for your specific model year.

The recommended oil change interval for the Infiniti G35 Coupe is every 5,000 miles or 6 months. Under severe driving conditions — track use, towing, or frequent cold starts — shorten this interval by 25–30%.

When servicing your Infiniti G35 Coupe, always replace the oil filter at every oil change. Using a quality filter — such as Fram, Mobil 1, or OEM equivalent filters — ensures clean oil circulation through the engine block.

Oil change costs for the Infiniti G35 Coupe at a US dealership or local service center typically range from $60 to $110 for a standard synthetic blend or full synthetic service. DIY oil changes cost approximately $30–$65 in parts (oil + filter) and take about 30 minutes with the right tools.

Always consult your vehicle's owner's manual to confirm the exact specification for your specific trim and engine variant, as some Infiniti G35 Coupe configurations may have different requirements.
