No reason to believe that you can’t run nitrile for 10kI'm going with Yogi's statement here, "it's deja vu all over again." As noted, similar statement from FB/Fram reps when black nitrile first showed up on EG/TG. At some later point, did admit black was nitrile caused by supply issues. Many here speculated that early on.
Want silicone adbv on MP series, look for blue or orange. Run black adbv MP for 5k, be fine. As for later burn test result, sticking with Accam's. To this point on adbv material, only wrong once.
