My dealer did that when I had an oil change on a Ford Aerostar and the tech laft the cap off and my engine seized. They had to replace the motor.

Ya, but the strength of an old man or woman isn’t going to be enough pressure to cause any damage. I’ve had one for my mom and sister, and they left no damage at all.

I have one of those for my mother, and she loved it. I haven’t noticed any damage at all to the car. Now my older sister who has cancer uses it, and she likes it. Make it easier for them to get out.
