If the oil light comes on, immediately pull over safely and turn off the engine. Do not continue driving.
Here's what you should do:
1. Check the oil level: Use the dipstick to check if the oil level is low. If it is, you'll need to add oil (the correct type and amount are specified in your owner's manual). After adding oil, let the engine run for a few minutes to allow the oil to circulate, then check the level again. If the light remains on after adding oil and the level is correct, then the problem is more serious.
2. Check for leaks: Inspect the engine for any visible oil leaks.
3. If the oil level is fine and there are no visible leaks, or if the light stays on after adding oil: The problem is likely more serious and requires professional attention. Do not attempt to drive the vehicle. Have it towed to a qualified mechanic or Chevrolet dealership. The problem could be a faulty oil pressure sensor, a failing oil pump, low oil pressure due to a worn engine, or something else.
In short: Adding oil might temporarily resolve a low oil level issue, but if the light remains on, it means there's a more serious problem that needs professional diagnosis and repair. Do not drive the vehicle until the issue is resolved.
