  2. Motor oil - Wikipedia

    en.wikipedia.org/wiki/Motor_oil

    An oil pump, a vane or gear pump powered by the engine, pumps the oil throughout the engine, including the oil filter. Oil filters can be a full flow or bypass type. In the crankcase of a vehicle engine, motor oil lubricates rotating or sliding surfaces between the crankshaft journal bearings (main bearings and big-end bearings) and rods ...

  3. Lubricant - Wikipedia

    en.wikipedia.org/wiki/Lubricant

    Lubricants may contain polar additives known as friction modifiers that chemically bind to metal surfaces to reduce surface friction even when there is insufficient bulk lubricant present for hydrodynamic lubrication, e.g. protecting the valve train in a car engine at startup. The base oil itself might also be polar in nature and as a result ...

  4. Oil sludge - Wikipedia

    en.wikipedia.org/wiki/Oil_sludge

    Oil sludge or black sludge is a gel-like or semi-solid deposit inside an internal combustion engine, that can create a catastrophic buildup. It is often the result of contaminated engine oil and occurs when moisture and/or high heat is introduced to engine oil.

  5. Friction modifier - Wikipedia

    en.wikipedia.org/wiki/Friction_modifier

    They are currently used in many engine oils and, more recently, in gear oils. [1] They reduce friction by forming two-dimensional molybdenum disulphide layers on rubbing surfaces. [4] Functionalized polymers, which can be tailored to adsorb specifically on polar surfaces, have been shown to markedly reduce friction and wear. [5]

  6. Oil prices have been falling for seven weeks straight. Here’s why

    Iran is producing 3.2 million, and the oil minister said he wants to get to 3.6 million by the end of the first quarter next year. So they’re ramping up and at the same time, Saudi Arabia is ...

  7. Oil pressure - Wikipedia

    en.wikipedia.org/wiki/Oil_pressure

    Murphy oil pressure gauges with switches that activate on low pressure. Oil pressure is an important factor in the longevity of most internal combustion engines. [1] With a forced lubrication system (invented by Frederick Lanchester), oil is picked up by a positive displacement oil pump and forced through oil galleries (passageways) into bearings, such as the main bearings, big end bearings ...
