Car doesn’t move until high RPMS.

I only question where full is when the car is cold. I’ve check it correctly before but never done it cold.

It's meant to be checked hot, in neutral.

If you are filling after a service I fill it to full line cold, not running. Start it, put it in neutral, recheck and keep adding until you're close. Get it to temp and check/ fill one more time.
