I would strongly advise using
two sissor jacks for emergency on the road, otherwise use a floor jack when at home in your garage.
And also to put some wheel blocks on the opposite side.
The car is very heavy and the more you are moving up the car,
the more it become difficult to crank up.
Having two sissors jack help to balance the load,
cranking is more easy by alaternatively cranking each jack, like one inch up at the time.
This is also more secure, not only by having two lifting point, but also
the big issue when lifting a car,
is that
the car might have tendency to slip a little bit in one direction, unless you are in a perfect flat location.
So when using two sissors jacks, you can then readjust the position of one of the jacks, to avoid the sissor jack to get too much torsion.
See a previous posting about the jacks I carry for emergency, a 2.5 T for the rear and a smaller one for the front.
Thanks for the write up. I knew those Modern Spare Jacks were crap. Get any OEM Jack used on Ebay, they will be a LOT more rugged. See my thread on the topic. The perfect Model 3 emergency jack?
