I use the Sector111 "flat jacks" which have the rubber pad on top (4 jack stands), to work on the car. I use the 1.5 ton harbor freight aluminum racing jack to lift the car onto the stands. I sometimes use a hockey puck (courtesy of BWR) on top of the aluminum racing jack lift point to get that extra inch to get the car on top of the sector111 flat jacks. With any lifting hydraulic jack, make sure it is rolling freely as you lift, so the lift point does not move reletive to the car's chassis. I refuse to pay dealer price for an oil change.
