For you guys with bad pistons, do you use the jack to hold the weight of the car for more than a minute etc., i.e. for the duration of the task, be it 5 minutes or 1 hr etc.

I'm wondering if the piston dies because it is carrying the weight for a prolonged period rather than just jacking it up and then resting it on jack-stands as soon as ppossible, thus alleviating the stress from the hydraulic jack for greater longevity.

* Still waiting for Costco to restock these jacks!
