Synthetic blends are usually a blend of high-quality and lower-quality conventional base oils, or all high-quality base conventional oils(Exxon Mobil Corporation). Synthetic blends are also called semi-refined oils, which are just actually less refined that full synthetic oils. You still get the same advantage of additives and more refinement, but you’ll have more impurities and there is actually the inconsistent molecular size of conventional oil in the blends.
