2005 Chevy 1500 Z-71 4X4 Oil Specificationsby JoAnn Joubert
The oil of a 2005 Chevy 1500 Z-71 4-by-4 vehicle should have the same weight and consistency of a 5W-30 oil, whether it be a suburban or truck. Changing the oil is a simple process, but be wary not to damage the oil filter. Also, if you choose to change the oil filter, be careful to properly install it because a poorly installed filter can severely damage your engine.

When to Change the Oil
You should change the oil in your 2005 Chevy 1500 Z-71 4-by-4 product when the computer within the vehicle notifies you that the engine revolutions and engine operating temperature have reached their maximum utility with the current oil. The oil life monitor on your dashboard should indicate the necessity of an oil change. However, the oil should be changed between 3,000 and 7,500 miles since your last oil change. After changing the oil, be sure to reset the oil life monitor by pressing the brake pedal three times while the truck is off, yet turned to accessory. The oil light will flash a few times before resetting.
