I think the comparison was being made to Toyota's oil, made by Exxon Mobil, vs. the Mobil 1 product. The oil made by Exxon Mobil with the Toyota label has a Toyota-specific additive package. I don't know that the additive is necessarily better. It's just what the engineers at Toyota designed for their engines.

I honestly don't know why Toyota makes it available for sale to the public since the service departments likely do not use it. I only use it when the price is about the same as something else I might buy. I don't buy a new vehicle often but I will pay extra for Toyota's oil for the first few oil changes on a new engine. I do assume this is what comes in the engine from the factory in Japan.
