The oil in an Infiniti M45 should be changed approximately every 5,000 miles or every six months, whichever comes first. Regular oil changes are crucial to maintain the engine's performance and prolong its lifespan. Neglecting to change the oil can result in reduced fuel efficiency, increased engine wear, and potential engine damage.

The power steering fluid level in an Infiniti M45 should be checked regularly, typically during routine oil changes or every 10,000 miles. Maintaining the proper power steering fluid level ensures smooth steering operation, prevents power steering system damage, and helps maintain optimal steering performance.

The spark plugs in an Infiniti M45 should be replaced approximately every 60,000 to 100,000 miles, depending on the specific model and driving conditions. Regular replacement of spark plugs ensures proper ignition, optimal fuel combustion, and helps maintain the engine's performance and fuel efficiency.

The timing belt in an Infiniti M45 should be replaced approximately every 90,000 to 105,000 miles or as recommended by the vehicle's owner's manual. Replacing the timing belt at the recommended interval helps prevent potential engine damage, ensures proper engine synchronization, and enhances overall engine performance.

The transmission fluid in an Infiniti M45 should be flushed and replaced approximately every 60,000 miles or every five years, depending on the driving conditions and manufacturer recommendations. Regular maintenance of the transmission fluid helps to ensure smooth gear shifts, prevent transmission damage, and extend the lifespan of the transmission system.

The cabin air filter in an Infiniti M45 should be replaced approximately every 15,000 to 30,000 miles or as recommended by the vehicle's owner's manual. Regular replacement of the cabin air filter ensures clean air circulation inside the vehicle, improves air conditioning and heating system efficiency, and helps prevent the build-up of allergens and pollutants.

The fuel filter in an Infiniti M45 should be replaced approximately every 60,000 to 90,000 miles or as recommended by the vehicle's owner's manual. Regular replacement of the fuel filter helps maintain fuel system cleanliness, prevent fuel delivery issues, and ensures optimal engine performance and fuel efficiency.

Infiniti recommends using premium unleaded gasoline with an octane rating of 91 or higher for the Infiniti M45. Using the recommended octane rating helps optimize engine performance, prevent knocking or pinging, and maintain the vehicle's fuel efficiency.

The recommended tire pressure for an Infiniti M45 typically ranges between 32 to 35 PSI (pounds per square inch), depending on the specific model and tire size. Maintaining the correct tire pressure improves fuel efficiency, enhances tire performance, and ensures optimal handling and safety on the road.

Infiniti recommends using a high-quality, maintenance-free battery with the appropriate specifications, usually a Group 35 or Group 24F battery, for the Infiniti M45. Using the recommended battery ensures proper electrical system operation, reliable starting power, and helps prevent potential electrical issues.

Infiniti recommends using a specific type of coolant, usually a long-life ethylene glycol-based coolant, for the Infiniti M45. This coolant is designed to provide excellent corrosion protection and heat transfer properties for the engine. Using the recommended coolant helps maintain optimal engine temperature, prevents overheating, and ensures the longevity of cooling system components.

Infiniti recommends using a high-quality synthetic motor oil with the appropriate viscosity grade, usually 5W-30, for the Infiniti M45. Synthetic oil provides better protection against engine wear, improves fuel efficiency, and offers enhanced performance, especially in extreme temperature conditions.
