the lower your car is, the less you should use the renault jack, as the biggest stress is in the low positions at the part what was bent. and usually there is no weight, but when lower, there is.
Own experience
I don't know your mechanical knowledge, but maybe it would be good to find a specialist local to you to take a look at your 172 if you are unsure about it. These cars must be enjoyed, they are made for it
They are turd. However I have to use mine as the jack I bought doesn't go low enough to fit under my car. Idiot.
I know Ad's private plate is a reflection of his name,
but whenever I see it I read it as T21 AIDS.
