[QUOTE="PistolWhip, post: 10233065, member: 30361"] I don't think anyone is saying that you’re flat out wrong by putting an additive in your oil. I think what UnleashedBeast is saying is that if you [B][I][U]NEED[/U][/I][/B] to put additives in the oil, you’re probably not using the best oil that you could be. The thing you need to understand about manufacturer recommended lubricants is that the manufacturer has a lot more to consider than just engine longevity. In fact, engine longevity is at the bottom of the engine oil priority list when the engineers decide which is best to recommend. As long as the engineer can guarantee that the engine lives beyond the warranty period (which is not a difficult task now a days with the way engines are built you can pretty much run cooking oil in them and get 50k miles out of them), the actual longevity beyond that is not even in the equasion let alone top priority list when deriving the recommended oil. They consider things like CAFE standards, federally mandated Catalytic Converter warranties and survivability, fuel mileage concerns and most of all, which one of their own in house oils will fit all of the above. Clearly they want to make as much money on the "aftermarket" as possible so they will never recommend an oil that they don't make. It's also not very smart business to recommend an oil that will lend to a high percentage of catalyst failure before the federally mandated warranty is up. So if you break it down, the pecking order when deriving a manufacturer recommended oil is: What do we make that will... Will it meet the latest API standard? Is it possible to reduce the additives enough to maintain Catalyst operation beyond 100k miles but still insure engine life beyond the much smaller 50k mile warranty? Will it give us the best possible rated fuel economy? AND that's about where the manufacturers cares end when it comes to recommending engine oil... There is NO law that limits the amount of zinc additives in motor oil. In order to meet the standard qualifications of API SM, the oil must come below a certain level of zinc and other additives. It's that simple and has nothing to do with law. So, if the oil company wants the oil to be able to wear the API SM approved label, it must conform to those specific standards. At the same time, in order to ever be one of many "manufacturer recommended" oils they must wear the API label. So, clearly the oil company is going to meet the standards in an effort to sell more oil... That certainly doesn't mean it’s the best standard or the best lubricent for a long lasting high performance engine.
