Many credible industry studies have shown oil takes time to set up (about 3k mi as a matter of fact), particularly zddp anti-wear additive - - anti-wear performance actually improves substantially with age/miles. By the time the oil hits 7500 mi, it's rockin. Nevertheless, impossible to convince folks of this.
