How is synthetic motor oil different from regular (conventional) motor oil?
Synthetic products are produced through a synthesis process that takes very small molecules and assembles them into larger designer molecules with premium lubricating properties. Others may be produced through a synthesis process that takes very large molecules, breaks them apart, and re-arranges them to produce designer molecules with premium lubricating properties. In either case, the end products are base fluids with extremely good lubricating properties. Conventional base stocks are refined from crude oil through various hydrorefined/hydrotreated refining processes to separate and/or convert undesirable compounds to yield a suitable finished base stock.
