I've been to all the major/well known PCMO manufacturers websites researching PDSs and such. The one odd thing I noticed while visiting them is that every last one of those mother [censored] say "unsurpassed wear protection". Not everybody can be "unsurpassed"! If one is then by logic the others cannot be. They also all say they're better than Mobil1 but ExxonMobil is still taking everyone to school when it comes to sales. Even the people that know good oil mostly seem to choose Mobil1. If these other companies were so much better, why haven't their sales held a candle to ExxonMobil's wallet? So when everybody on the market is better than Mobil and everybody is apparently "unsurpassed" in wear protection, what exactly is false advertising then?
