	Lubricating oils of different viscosities can be blended together, and it is this ability to blend them that makes some oils so useful. For example, common motor oil - shown in Figure 1 - is generally a blend of low viscosity oil to allow for easy starting at cool [[temperature]]s and a high viscosity oil for better performance at normal running temperatures.<ref name="RE1"/>		Lubricating oils of different viscosities can be blended together, and it is this ability to blend them that makes some oils so useful.

There are two basic categories of lubricating oil: mineral and synthetic. '''Mineral oils''' are lubricating oils [[oil refinery|refined]] from naturally occurring [[crude oil]]. '''Synthetic oils''' are lubricating oils that are manufactured.<ref name="RE1">How Are Products Made. (September 8, 2015). ''How lubricating oil is made'' [Online].

==Use in Vehicles==
The use of lubricating oils in vehicles is vital to their operation. When an [[engine]] is properly lubricated, it needs to put less work into moving [[piston]]s as the pistons glide easily. In the long run, this means that the car is able to operate while using less [[fuel]] and run at a lower temperature. Overall, the proper use of lubricating oil in a car improves [[efficiency]] and reduces the amount of wear and tear on moving engine parts.<ref>Kristen Hall-Geisler. (September 20, 2015). ''Engine Lubrication System'' [Online]. Available: http://auto.howstuffworks.com/engine-lubrication-system2.htm</ref>

==Recycling==
Since lubricating oils are such a valuable resource, there have been many efforts to recycle used oils. Used lubricating oil is recycled at "re-refineries", where [[water]] is removed from the oil in a process of dehydration. Impurities within the used oil - such as industrial fuel - are separated out and the oil is captured using [[vacuum distillation]]. This leaves behind a heavy waste that contains oil additives and byproducts. The extracted lubricating oil then undergoes a series of refining processes to remove other impurities. Once refined, the oil is separated into three different viscosities for a variety of uses.<ref>Australian Government Department of Environment. (September 20, 2015).
