Just out of curiosity, there hasn't been an oil leak during the last 2 days. I have some cardboard boxes underneath the x in my garage. Any advise?

Off topic, I've noticed my heater/fan speed is all over the board. Have it on high and it blows like a beast then all of a sudden it reduces a lot even though on high. Crazy thing is I feel like it fluctuates during turns. Wondering if I need a new blower motor or something like that.
