Just bought a 99 Boxster and finally exposed the engine compartment. When I checked the power steering fluid level, it does not even register on the dip stick. I looked into the reservoir and cannot see any fluid at all. The car seems a bit hard to steer, but I thought that was just normal. Could I be driving it without any power steering assist and not even know it?? I would think I would hear some bad sounds or something?? I will pick up some of the Pentosin fluid as soon as I can, but any advise would be appreciated
