I checked my oil and the dipstick was reading just below the two fill lines. That means it needs a quart, right? Like any other car? I had 1/3 of a qt in my garage, so I dumped it in just to get me to a gas station. I checked it again and the level was the same. So I went to the gas station and put 1/2 a qt. in. Checked it. Still no change. I then dumped in the rest of the oil, totaling about 1.33 qt. I then drove about 20 miles and checked it again. Now it reads WAAAYYY over-full! Like 2 inches above the full line! Then I had to drive it home like that. What did I do wrong? And now what sort of mess do I have? Did I hurt it driving it like that?
