Older I got, the more nervous in the service dept I get. Will not get under a car (other than just reaching in) with any lift system that allows air between top and bottom. So have a pile of of 1" X12" X24" boards that after using jack to lift wheel I put under tire. Four of these boards have a 2X4X12 screwed on to front and back, they are always the top board to keep car from going forward or backward.
Also took a series of boards 6',5',4',3',2' lined em up even at one end, voila a ramp, screw 'em together, 2X4 at high end--can push car up.
Oil change should be possible without any lift,most big box parts stores have metal pan that fits under oil pan, can get an extra inch or two with floor jack as needed, I always do that anyway after most oil drained to tilt pan for extra little bit
