2004 Infiniti q45 how to change oil?

To change the oil in a 2004 Infiniti Q45, start by warming up the engine slightly to thin the oil, then turn it off and allow it to cool for a few minutes. Secure the vehicle on a level surface, raise it with jack stands, and place an oil catch pan under the oil pan. Remove the drain plug and let the old oil drain completely, then replace the plug. Finally, remove and replace the oil filter, fill the engine with new oil through the oil filler cap, and check the oil level with the dipstick.
