Ok... so apparently my '98 200SX SE is losing oil. It is not leaking, and it is not burning oil. I'm positive of the first and almost positive of the latter. I've had my friends drive behind me and look for blue smoke--or any smoke for that matter--and we've revved it to redline at idle looking for smoke or any sign of the engine burning oil. There is no black residue on the back of my car, and we've all been up under the car and there is no sign of oil anywhere. I can park anywhere for any length of time and no oil shows up. Where is my oil going? HELP!
