So I changed my oil today, and took off to work on a friends computer. He's about two miles away. Got to his house and after a while had to come back home to get a cable and off again to his house. Fix the computer, hopped on the "Biglet" at got about 3 or 4 blocks away before noticing something just isn't right. Stopped and looked at the left side where a strong blast of air was coming from and oops... NO STINKING OIL CAP!!! :BLAM: And a wet oily pants leg to boot. Boot was oily too. So back tracked very slowly at an idle to his place looking for the cap. Found it in the middle of his drive way. Put it on, checked the oil, just below the full line and tightened it with some pliers this time, not just by hand. Guess I got lucky that I wasn't doing 70 somewhere and not noticing it was gone, because the engine would have been gone by the time I saw a low oil light.
