Yes, I'm an idiot. I was adding hydraulic fluid to my 580sl and needed a new 5 gallon can. So I just grabbed a new traveler's brand pail from tsc that I had and opened it up and put the pump in it. After putting in a gallon or so I noticed that the fluid was going in slower that usual. It's about 45 degrees in the building so I didn't think much of it. Then i happened to notice that it's 80/90 and not hydraulic fluid. I don't remember even having a new pail of 80/90. Anyways, do I need to drain the hydraulic fluid now? I assume I do but I hate to do it if I don't need to since it was recently changed.
Thanks
