Can I use just a hydraulic jack without jack stands?

Hydraulic jacks are mechanical lifting devices rather than secure structural supports, meaning they can fail without warning and should never be relied on alone. Attempting vehicle maintenance under a car held only by a jack creates an extreme safety hazard that prevents safe repairs when proper equipment is financially out of reach.

Should I lift each side of the car using 2 hydrolic jacks and swap tires, or buy a spare tire and do one corner at a time? The later requires more labour.source ↗

I just don't know if it's dumb to lift one side of the car at a time with 2 hydrolic jacks.source ↗

I assume you mean at a dealer or shop? The thing is I will be doing this to 3 new SUVs and swapping winter tires on all 3 as well. I figured DIY would be more economical in the long run.source ↗

Me and my manager have been getting into arguments, because I refuse to touch a car if they rotated tires after I told them they couldn't be.source ↗

There is another manager saying I should be written up for insubordination.source ↗

I told him straight up that I'm not doing it. I'm pretty sure the risk is small, but I don't know the consequences of something does happen, and I don't want to find out.source ↗

I know the answer is Jack Stands, but I physically cannot afford themsource ↗

Can I realistically trust the Jack to hold the car up for the 15 minutes it would take me to do the oil change?source ↗
