Motor oil or engine oil is an oil used for lubrication of various internal combustion engines. The main function is to lubricate moving parts; it also cleans, inhibits corrosion, improves sealing, and cools the engine by carrying heat away from moving parts.
Motor oils are derived from petroleum-based and non-petroleum-synthesized chemical compounds. Motor oils today are mainly blended by using base oils composed of hydrocarbons, polyalphaolefins (PAO), and polyinternal olefins (PIO), thus organic compounds consisting entirely of carbon and hydrogen. The base oils of some high-performance motor oils however contain up to 20% by weight of esters.
Motor oil is a lubricant used in internal combustion engines. These include motor or road vehicles such as cars and motorcycles, heavier vehicles such as buses and commercial vehicles, non-road vehicles such as go-karts, snowmobiles, boats (fixed engine installations and outboards), lawn mowers, large agricultural and construction equipment, locomotives and aircraft and static engines such as electrical generators. In engines, there are parts which move against each other causing friction which wastes otherwise useful power by converting the energy to heat. Contact between moving surfaces also wears away those parts, which could lead to lower efficiency and degradation of the engine. This increases fuel consumption, decreases power output and can, in extreme cases lead to engine failure.
This afternoon me and my roommate changed my oil I felt like a man as I drained my oil pan I put my car up on bricks now there's nothing I can't fix if I could put you up on bricks I've never changed my own oil he said I was three quarts low he shook his head he shook his head and said dan you're bad I said sometimes I forget and it might just be genetic cars escape me just like my dad and I should probably think more about where I'm going and how I'll get there and I should probably check my tire pressure keep it high so I don't stall don't stall we gapped spark plugs and I guess I learned something new but I felt bad for that poor guy at Jiffy lube he'll change oil, and I'll write songs and we'll all still get along forgive me I meant no wrong
