I didn't get a chance to look for an oil trail; it seized up in the middle of that hail storm. There was about 4 inches of hail and water on the road that I was plowing my way through (craziest thing I've ever seen). I don't think it dumped the oil all at once... it's more likely that it just started using/leaking oil faster than I was used to. Over the past six months, with all the repairs and replaced parts I had been doing, it started to use less and less oil. As a result, I got out of the habit of checking the oil level everytime I filled up the gas tank. It was kinda nice... almost like having a normal vehicle. Oh well.
As for the mileage, I had just hit 151k a few days before...
