I lift my car all the time at the designated spot (behind the wheel well near the firewall). I use some wood and half height concrete blocks to get the car high enough off the ground to get the jack under it, then I have a chunk of wood in the jack circle to avoid mangling metal to metal.
I also only use 6 sided sockets as I learned my lesson as a child.
In fact, until the powertrain warranty expires (mine will be due to mileage) I bring my Volt to the dealership for oil changes. I figured if the ICE blew up due to a low oil condition, and the dealership is the only one to touch the oil, it's on them and not me. I had a coworker who blew his Chrysler Conquest engine years ago, and Mopar would not cover repair with the 10 year 100K warranty citing a low oil condition. He could not produce records of periodic oil changes since he did some himself, did some at a jiffy lube.
I plan to change my own oil once I'm beyond the warranty. I've heard it's really simple. I guess I won't find out for 20+K miles or so.
