Understanding the Oil Light

The oil light on your 2001 GMC Sierra serves as a crucial warning system. It illuminates when the oil pressure in your engine drops below a safe level. This can occur for several reasons, including:

• Oil filter blockage: A clogged oil filter restricts oil flow.
• Oil leak: A leak in your engine can cause oil loss.

Ignoring the oil light can lead to serious engine damage. If the light comes on, it’s crucial to address the issue immediately.
