Infiniti M45 Manufacturer Oil Approval Reminder

Many Infiniti M45 engines require oils meeting specific manufacturer-required oil approval standards or certifications (such as API SP or ILSAC GF-6). Confirm the correct specification in the owner's manual before buying oil.

Severe Service Change Intervals

Short trips, long idling, dusty roads, extreme heat or cold, aggressive driving, frequent stop-and-go traffic, and repeated city use can justify a shorter oil change interval. Follow the severe-service schedule in the owner’s manual when it applies.

Infiniti M45 DIY Oil Buying Guide

Most Infiniti M45 records on this page are near 6.5 quarts with filter, but some years differ. After selecting the exact year, buy enough oil to cover the listed capacity and keep a small reserve for top-off. Add oil gradually and recheck the level instead of pouring the full amount at once. Oil change prices vary by shop, oil approval, filter type, location, and engine. Use the listed capacity to estimate oil quantity, then compare local shop quotes or DIY parts cost.

DIY Oil Change Checklist

Confirm year and engine block displacement

Check exact quarts required with filter

Buy correct SAE viscosity grade (e.g. 0W-20 or 5W-30)

Confirm Infiniti approval standards

Use a filter that matches the exact Infiniti M45 year, engine, and housing style. Do not buy filters by make and model alone.

Do not overfill — top off gradually
