Yes, very normal.
The check engine light comes on when the ignition is on and the engine
is not running. It is a reminder to start the engine.
The check oil light comes on when the ignition is on and the oil
pressure is low. When the engine is not running, the oil pressure is
very low, zero.

the owners manual usually addresses such things.
You should read it if you have one.
If you don't have one ...order one from dealer.
