All engine oils are made of base oils and additives. Fully synthetic engine oils contain 100% non-conventional, high-performance fluids. Semi-synthetic engine oils (also called “blends”) contain a smaller percentage of these high-performance fluids in combination with conventional mineral oil. Mobil 1 is a fully synthetic motor oil.
