The first type of oil that we will list is conventional motor oil. Conventional motor oil is the oldest type of oil out there. This type of oil is mineral-based, which means that it is derived from mineral sources. Such as crude oil.

This type of oil is basically a by-product of the refinement of crude oil into gasoline or diesel. So, in order for refineries not to throw it away, they produce lubricants out of it. This type of oil is rich in zinc and it is the way to go for older motors that were not designed to work on synthetic oils.

The second type that we are going to cover is the synthetic blend. Also known as semi-synthetic. This type of oil is mostly mineral-based. But improved with some synthetic properties that make it last far longer than the regular mineral oil. This type is most commonly known as the best high mileage oil.

The lower the first number the thicker the oil is at low temperatures. So, if you live in cold climates, you should get something like 10w-20 instead of 0w-40. The oil that is rated at zero, is really thick and will not work with your engine.

The second two digits indicate the performance of the oil in high temperatures. The higher the number is the thinner the oil is at high temperatures.
