Essentially, you can choose between two types of motor oil for your vehicle: synthetic and conventional oil. Most cars can use both types of oil, but depending on your car’s condition, you may benefit from picking one option or the other.
Conventional oil is cheaper than synthetic oil. However, you’ll need to pay to replace it more often than the alternative, and it is less capable of dealing with changing temperatures. Synthetic oil costs more but won’t need to be replaced as regularly and can provide better lubrication than conventional oil.
