Most 'dino' oils have about 20-25% additives, depending on viscosity and brand. But that figure is almost universal

Mobil 1 has about 10-12% additives, far less than 'dino' oil, because the synthetic base stocks are much, much closer to 'perfect' and able to do an outstanding job without the use of nearly as many additives, which can be thought of as modifiers or 'band-aids'. This higher percentage of actual OIL in the Mobil 1 formula lets the oil lubricate and cool your engine better. That is why engines that use a good synthetic get noticeably better mileage, run cooler, last longer, make more power, and produce fewer emissions. But to me, the most important reason that I use Mobil 1 is because there are no trace elements in it. None! Remember, it is the sulfur and phosphorous that helps lead to sludge formation in an engine. Without these trace elements in the oil, the formation of sludge is remarkably reduced. Engines that are run exclusively on Mobil 1 stay unbelievably clean and sludge-free. Sludge is far and away the leading cause of engine failure. That's why I don't like the Castrol synthetic product: It still contains many trace elements. Now Amsoil advertises that their oil is the 'extended drain interval' oil. They do this by pumping up the additive package. They can have as much as 3 times as many additives as Mobil 1, so in theory it can take more 'shearing', lasting longer. More additives means less actual oil in the mix, resulting in less lubrication, less cooling, more wear and tear...you know the rest. The oil may last longer, but at what price? Your engine? That's not a good trade off for me. Don't get me wrong. Amsoil is a very good oil, but no matter how good any oil is, your engine is still going to produce contaminants and by-products, and the longer they are in your engine the more damage being done.
