we just hit 9200 miles and like clockwork the oil light came on as it does every 1k miles. time for at least another quart - but that's "normal". can't wait for this tramp to get menopause.
Luckily my CT doesn't have any oil consumption issues, I've added one quart (no warning light, just routine check) in 14K miles. Interestingly enough, after the original set of problems I had with the car I haven't had a single problem since - other than the hesitation issue.
Guys, you better cross your fingers when saying that "these problems" never happen to you again because I did the same thing and the next day, I had the altenator problem, it took them a week to fix it because they had to order the part from Germany.
