You guys sure this blower stores 8 oz. of oil? I changed it todaya nd I don't think I got that much out and I certainly didn't put that much back in. My car was level and I kept shooting oil back in until it started to come out of the drain hole, which in turn I quickly plugged. And when I was removing the blower I was shoving that hose in there in every imaginable angle trying to make sure I sucked out all the oil. Now I'm wondering if I still have a lot of old oil in there and I used 10w - 30. I'm pissed.
It's fine if you took less out than what you put in if you feel you sucked it out. On a level surface I would take the drain plug out again and allow the oil to come out since you plugged it up while it was still leveling off. Once all the fluid drains out plug it up again....just like a differential
