  2. SAE J300 - Wikipedia

    en.wikipedia.org/wiki/SAE_J300

    The oil fails the test at a particular temperature if the oil is too viscous. The grade of the oil is that associated with the coldest temperature at which the oil passes the test. For example, if an oil passes at the specified temperatures for 10W and 5W, but fails at the 0W temperature, the oil is grade 5W. It cannot be labeled 0W or 10W.

  3. Motor oil - Wikipedia

    en.wikipedia.org/wiki/Motor_oil

    Motor oil, engine oil, or engine lubricant is any one of various substances used for the lubrication of internal combustion engines. They typically consist of base oils enhanced with various additives, particularly antiwear additives , detergents, dispersants , and, for multi-grade oils, viscosity index improvers .

  4. Calculated Carbon Aromaticity Index - Wikipedia

    en.wikipedia.org/wiki/Calculated_Carbon_Aromati...

    The running of all internal combustion engines is dependent on the ignition quality of the fuel. For spark-ignition engines the fuel has an octane rating. For diesel engines it depends on the type of fuel, for distillate fuels the cetane numbers are used. Cetane numbers are tested using a special test engine and the existing engine was not made ...

  5. Viscosity index - Wikipedia

    en.wikipedia.org/wiki/Viscosity_index

    Historically, there were two different oil types recommended for usage in different weather conditions. As an example, with winter oils and cold starting the engines, and with temperature ranges from, say, −30 °C to 0 °C, a 5 weight oil would be pumpable at the very low temperatures and the generally cooler engine operating temperatures.

  6. Two-stroke oil - Wikipedia

    en.wikipedia.org/wiki/Two-stroke_oil

    The oil is dyed blue to make it easier to recognize in the gasoline. It appears black in this bottle because it is not diluted. Two-stroke oil (also referred to as two-cycle oil, 2-cycle oil, 2T oil, or 2-stroke oil) is a type of motor oil intended for use in crankcase compression two-stroke engines, typical of small gasoline-powered engines.

  7. Oil pump (internal combustion engine) - Wikipedia

    en.wikipedia.org/wiki/Oil_pump_(internal...

    Indications of low oil pressure may be that the warning light is on, a low pressure reading on the gauge, or clattering/clinking noises from the engine. Low oil pressure is a problem that must be addressed immediately to prevent serious damage. The leading cause of low oil pressure in an engine is wear on the engine's vital parts.

    en.wikipedia.org/wiki/Subaru_FB_engine

    The FB is built at Gunma Oizumi Plant and was initially available as a 2.5 litre displacement engine, starting in Forester models, with a 2.0 litre model to follow in Imprezas. [1] [4] 0W–20 oil is used to help fuel economy, and approximately 1 litre more oil is used as the newly adopted timing chain requires an oil supply. [2]

  9. Total base number - Wikipedia

    en.wikipedia.org/wiki/Total_Base_Number

    Base Number (BN) is a measurement of basicity that is expressed in terms of the number of milligrams of potassium hydroxide per gram of oil sample (mg KOH/g). BN is an important measurement in petroleum products, and the value varies depending on its application.
