Mobil Drive Clean (5000 *and* 7500).
I used DC 5k during my break-in period for roughly 5k miles as the first oil I changed to after the Factory Fill. I then used the Mobil Drive Clean 7500 for another 11,500 miles. During this time, I recall stacking up nice with a certain S2000 doing stop light excavation on Westheimer so I know the oil performs and aids in that regard. I will have to qualify all of this by saying that it was the oil I used immediately after the Mobil series at 21,500 on the ODO that was the MC that provided me the greatest asset with which to compete ahem (beat) a certain Supra motor but all of this is neither here nor there as far as your question.
