Come to think of it I filled up the oil before I left that day and I spilled some so that is probably oil.
My dipstick was reading really weird though. I took it out I wiped it off and I put it back in and when I pulled it out again it had nothing. So I freaked out but then I tried the same thing later and it said nothing again, but when I put it in a 3rd time I moved it around a little bit and it said it was full.
Am I doing something wrong?
