MDO is widely used by medium speed and medium/high speed marine diesel engines. It is also used in the larger low speed and medium speed propulsion engine which normally burn residual fuel. [1] Those fuels result from a catalytic cracking and visbreaking refinery. [1] Marine diesel oil has been condemned for its nimiety of sulfur, so many ...
MGO (Marine gas oil) - Roughly equivalent to no. 2 fuel oil, made from distillate only; MDO (Marine diesel oil) - Roughly equivalent to no. 3 fuel oil, a blend of heavy gasoil that may contain very small amounts of black refinery feed stocks, but has a low viscosity up to 12 cSt so it need not be heated for use in internal combustion engines
Data available until 2011 for fuel oil sales to the international marine shipping sector reports 207.5 million tonnes total fuel oil sales with HFO accounting for 177.9 million tonnes. [9] Marine vessels can use a variety of different fuels for the purpose of propulsion, which are divided into two broad categories: residual oils or distillates.
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.
It is the only remaining, not revoked classification of the API Two-Cycle motor oil specifications (TA, TB, TC, TD). Being a very old standard itself, most currently produced 2T lubricants meet its specifications, even the lowest quality ones; current high-quality oils exceed them (often labeled "API TC+" although not based on actual measurements).
MMboe – million barrels of oil equivalent; MMboed – million barrels of oil equivalent per day; MMbpd – million barrels per day; MMcf – million cubic feet (of natural gas) MMcfe – million cubic feet (of natural gas equivalent) MMcfge – million cubic feet (of natural gas equivalent) MMS – Minerals Management Service (United States)
The oil and the oil filter need to be periodically replaced; the process is called an oil change. While there is an entire industry surrounding regular oil changes and maintenance, an oil change is a relatively simple car maintenance operation that many car owners can do themselves.
The NLGI consistency number is also a component of the code specified in standard ISO 6743-9 “lubricants, industrial oils and related products (class L) — classification — part 9: family X (greases)”. [1] The NLGI consistency number alone is not sufficient for specifying the grease required by a particular application.
