2. Motor oil - Wikipedia

   en.wikipedia.org/wiki/Motor_oil

   Motor oil is a lubricant used in internal combustion engines, which power cars, motorcycles, lawnmowers, engine-generators, and many other machines. In engines, there are parts which move against each other, and the friction between the parts wastes otherwise useful power by converting kinetic energy into heat.

3. Oil filter - Wikipedia

   en.wikipedia.org/wiki/Oil_filter

   Oil filter. An oil filter is a filter designed to remove contaminants from engine oil, transmission oil, lubricating oil, or hydraulic oil. Their chief use is in internal-combustion engines for motor vehicles (both on- and off-road ), powered aircraft, railway locomotives, ships and boats, and static engines such as generators and pumps.

4. Oil additive - Wikipedia

   en.wikipedia.org/wiki/Oil_additive

   Oil additive. Oil additives are chemical compounds that improve the lubricant performance of base oil (or oil "base stock"). The manufacturer of many different oils can utilize the same base stock for each formulation and can choose different additives for each specific application. Additives comprise up to 5% by weight of some oils.

5. Crankcase ventilation system - Wikipedia

   en.wikipedia.org/wiki/Crankcase_ventilation_system

   A crankcase ventilation system ( CVS) removes unwanted gases from the crankcase of an internal combustion engine. The system usually consists of a tube, a one-way valve and a vacuum source (such as the inlet manifold ). The unwanted gases, called "blow-by", are gases from the combustion chamber which have leaked past the piston rings.

6. Kerosene - Wikipedia

   en.wikipedia.org/wiki/Kerosene

   Kerosene, or paraffin, is a combustible hydrocarbon liquid which is derived from petroleum. It is widely used as a fuel in aviation as well as households. Its name derives from Greek: κηρός ( kērós) meaning "wax", and was registered as a trademark by Nova Scotia geologist and inventor Abraham Gesner in 1854 before evolving into a generic ...

7. Oil purification - Wikipedia

   en.wikipedia.org/wiki/Oil_Purification

   Oil purification cleans oil from contaminants. it can be used independently or as a part of oil regeneration. Oil regeneration also removes aging products (with the help of adsorbents) and stabilizes oil with additives. Regenerated oil is clean from carcinogenic products of oil aging and stabilized with the help of additives.
