Got a used 2004 CTT about a month ago. I do mostly short, city driving (about 3-4 miles a day round trip beleive it or not). Do you expect more or less oil consumption for this type of driving? I checked the oil a week or so ago, and it seemed fine. I checked it this morning, and to my dismay it was very low (not low enough for the oil warning light to come on). Fortunately I had a quart of Mobil 1 handy. Any thoughts would be appreciated. Also, how low does the oil have to get for the oil warning light to turn on? I dumped in a full quart and it brought the oil level to a little less than half way between the max and min marks on the dip stick. Part of the problem, I beleive, is that the car was not fully up to temperature before I checked the oil level. Thanks.

 

One quart every 1k-2k miles is typical for a CTT.
