Viscosity is a fluid's resistance to flow and listed on motor oil as an alphanumerical value, such as 5W-20 or 5W-30. Owner's manuals often recommend two oil viscosity values for vehicles. Conventional oil is the cheapest type of oil that meets API and SAE standards. Premium conventional oil is the standard oil for newer vehicles. Full-synthetic oil is beneficial to high-tech engines that require superior performance, although it is more expensive than other types of oil.
