On my car, the oil plug faces the back, so if anything, it's easier for oil to drain from the back of the pan. Either way, as long as you can get the car on ramps, you will be fine changing the oil. I've been using ramps for 5+ years, the same pair actually, and it does great. Have used them to change oil in multiple vehicles. The only car I didn't use them for was a lowered car that only the floor jack could get under (yes it was that low). Use ramps and sleep sound!
