Yes, but it’s a good idea to maximize safety by inspecting each ramp for cracks, damage or missing anti-skid pads prior to use. Line them up and ensure that each tire sits fully within the width of the pad. Always set your parking brake and place wheel chocks behind the rear wheels before going underneath the car. When filling oil, add an amount just under the factory capacity, back the vehicle off the ramps onto level ground, and check the oil level again to fill it to the proper level.
