Must be the fact I own Harbor Freight (Horrible Fright) floor jacks and trolley jacks, but not for a million dollars would I do anything without jack stands, even without removing the tires, if I can't fit under it with a foot to spare, it gets jack stands (well, oil changes are on ramps).
Even with as minimally as I drive mine, I do at least 3 oil changes a year. I am not sure I really trust the oil life indicator as it has me do it every 2,000 miles ( ASSUME it isn't just mileage based, but other things like the fact it spends 40% of its life at WOT), I reset it once and change the next time it goes off, usually around 4,000->4,500 miles.
My Grand Marquis...I am due for my 61st oil change since owning it, and that even includes the 2 changes with Mobil 1 extended 15,000 mile changes.
