I have the same jack (but with Craftsman's name badge), it won't even reach the frame on my Pathys. I picked up a 3 ton in a nice set and it has a max height of about 2', it can barely get the wheels off the ground by jacking on the frame, but at least it CAN get them clear. I only use the little guy on little cars, it is 1" shorter at it's lowest and can fit under cars better.
BTW is there any way to refill the little ones? I think mine has an air bubble in it or something. I only get lift with like the last 1/2" on the stroke.
