This will then put stress, wear, and tear on your engine. And the oil in your vehicle is still not warm and will not flow.  

Revving Your Vehicle Will Make It Like It Is Driving

If you rev your engine, you are not driving. But your engine will still get pushed through. It can be tough on your vehicle.
