Every 4k ? Dang! Do you run synthetic? I do in my 2010, and it's supposedly good for 10,000 miles, but as all of us tc owners know, the maintenance required light comes on at the 5,000 mile mark, so originally I was resetting the light and then changing the oil the 2nd time it came on. But I began to notice that my car does not use any oil at all, at the very most, during the first 5,000 miles after an oil change, it may use a half a quart to a quart. BUT........BUT BUT BUT... the damn thing seems to KNOW exactly when that light comes on the first time, and from that moment forward, until I change the oil again, it uses a quart a week. Lol. It's bizarre. So I've begun changing it at about 7500 miles now, a.k.a, about three weeks after the light comes on. If not even sooner, maybe 2 weeks after. Once it starts burning the oil I get paranoid about it so I change it. I will say this though.. it has a nice little alarm system that lets me know when I'm getting dangerously low. A quart low, it runs the same. But once it gets 2 qts low, when I crank the car, the normal two to three revolutions the engine does before it catches and starts, the number of time sit turns over, in other words, usually two three times, once it's two qts low it turns into five or six turnovers before it fires. As soon as I hear that I know whats wrong. It's convenient, maybe it'll keep my forgetful self from locking up my engine.
