I know oil consumption threads are all over this forum, its actually what saved me from what would have been a big mess. I am getting towards my first (although the previous owner had the a few oil changes done) and figured it was a bit since I checked my oil. My other vehicles had all been diesel trucks which unless your leaking oil it is very rare to have to add oil between changes.
Anyways reading through a few of the oil posts I figured it would be a good idea to check the oil. Sure enough it was right at the very bottom of the dipstick, thank god it was still on it. I added about 1 1/4 quarts to it and it will be getting changed here right away (just before I park it for the winter).
Had a good scare this weekend, and now I am going to religiously check it at every fill up. If you haven't checked your oil in the last 500 miles I suggest you do it.
