Why does my oil warning light come on?

What does a car oil warning mean?
The dashboard oil light comes on when your engine suffers a drop in oil pressure. Without enough oil pressure, the engine can’t lubricate itself. Continuous lubrication is necessary for the engine to run, so if it’s not adequately lubricated it will seize, and it could stop abruptly, which could cause an accident.

The oil won’t run through the components of your engine to accurately lubricate the vehicle’s system.

Why does my car take so long to warm up in cold weather?
There’s a few reasons why a carbureted car wants to take more time to warm up in very cold weather: first, it’s likely older, and that means getting less-viscous oil to as much of the engine as possible is even more important; same goes for getting some heat into all the cold, brittle rubber hoses and connectors and so on.
