ok, so last week I *attempt* to check my oil with the car running, as per the manual. I unscrewed the cap, it's VERY hot, wipe it off, put it back in w/o screwing it down. I pull it out, and oil's all over the stick, can't get an accurate reading. So, I try it again, same results. Finally, I shut it down, put the dipstick in, and get a full reading. What am I doing wrong here? The car was very hot, and had just been driven hard for an hr. Is that why I couldn't get an accurate reading while it was running, it was TOO hot?
