I have used Redline synthetic in my Subaru for a while now and have been very happy with how steady it keeps oil pressures throughout various temperatures, and has stopped my 2.2 from burning oil. But I just learned about a company named MPT Industries who claims to use higher quality base stocks and yotta yotta yotta. But their "street" oils have a high quantity of zinc and phosphorus (Typically only reserved for "racing" oil) which implies it's going to unnecessarily bully my cat/con and do more bad than good since Yolanda the Honda doesn't get raced like the Subaru. Has anyone had experiences with either company? I would like to see some UOA from each of the companies after use in a Honda engine. And I beg you, please don't start an argument about some other oil company being better for half the price, nobody want to sort though that junk. If you have no first-person data to add, don't comment please.
