It is amazing engineering... whether base or additive... synthetics are purified and uniform...

"Synthetic oil is not only refined but also distilled, purified and
broken down into its basic molecules. This process not only removes
more impurities from the crude oil, but also enables individual
molecules in the oil to be tailored to the demands of modern engines.
These customized molecules provide higher levels of protection and
performance than conventional oils."

"Pure, Uniform Molecules Form Strong, Stable Lubricants
Petroleum oils have molecular structures that are randomly organized
and, consequently, have limited performance abilities. Their varied
and inconsistent molecular structure results in less film strength and
lubricity. Their paraffinic wax content also makes them more
susceptible to viscosity variance and cold-temperature flow problems."
