According to the MSDS for each product, the EP contains more PAO. Otherwise, they are VERY similar as noted.
Very similar and probably formulated sightly different for the reasons they are labeled differently.

Full synthetic oil uses a synthetic base stock mixed with a variety of additives that boost the performance of the oil. While all synthetics on the market may offer a higher level of protection than conventional or synthetics blends, not all synthetics are equal. Each synthetic brand uses a mix of high-performance fluids and additives. How these formulations come together results in various protection levels and attributes.
o not all synthetics provide the same protection? Why not?
Here’s why. Not all synthetics are formulated the same way. They can contain very different types and combinations of base oils and additives. Even minor differences in formulation can have a major effect on performance. For example, add a bit more of one additive and you get better cleanliness, but you might lose some wear protection. Cut back on this additive and you get better performance at high temperatures, but the cold-weather startup isn’t as good.
So, what’s a guy (or gal) to do? The best approach is to look for a full synthetic product that offers optimal performance in every area. That way, you’re not getting short changed in one area just to get better performance in another. Also, be sure to select synthetic oils that use high-quality base stocks to ensure powerful performance and protection.
