2. Marine diesel oil - Wikipedia

   en.wikipedia.org/wiki/Marine_diesel_oil

   Marine diesel oil (MDO) is a type of distillate diesel oil. Marine diesel oil is also called distillate marine diesel. [1] 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]

3. 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 special type of motor oil intended for use in crankcase compression two-stroke engines, typical of small gasoline-powered ...

4. Fuel oil - Wikipedia

   en.wikipedia.org/wiki/Fuel_oil

   In the Russian practice, though, "mazut" is an umbrella term roughly synonymous with the fuel oil in general, that covers most of the types mentioned above, except US grades 1 and 2/3, for which separate terms exist (kerosene and diesel fuel/solar oil respectively — Russian practice doesn't differentiate between diesel fuel and heating oil ...

5. Saturate, aromatic, resin and asphaltene - Wikipedia

   en.wikipedia.org/wiki/Saturate,_Aromatic,_Resin...

   Saturate, Aromatic, Resin and Asphaltene (SARA) is an analysis method that divides crude oil components according to their polarizability and polarity. The saturate fraction consists of nonpolar material including linear, branched, and cyclic saturated hydrocarbons ().

6. Heavy crude oil - Wikipedia

   en.wikipedia.org/wiki/Heavy_crude_oil

   Heavy oil is asphaltic and contains asphaltenes and resins. It is "heavy" (dense and viscous) due to the high ratio of aromatics and naphthenes to linear alkanes and high levels of NSOs (nitrogen, sulfur, oxygen and heavy metals). Heavy oil has a higher percentage of compounds with over 60 carbon atoms and hence a high boiling point and ...

7. 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.

8. Urals oil - Wikipedia

   en.wikipedia.org/wiki/Urals_oil

   Urals grade oil was traded in Northwestern Europe on June 25, 2020, at a premium to Brent of $2.35/bbl – a record in the entire history of monitoring since September 1994. [4] Since the 2022 Russian invasion of Ukraine , the price of Urals oil has dipped to $15–20 under the price of Brent.

9. Ramsbottom carbon residue - Wikipedia

   en.wikipedia.org/wiki/Ramsbottom_Carbon_Residue

   The Ramsbottom test is used to measure carbon residues of an oil. In brief, the carbon residue of a fuel is the tendency to form carbon deposits under high temperature conditions in an inert atmosphere. This is an important value for the crude oil refinery, and usually one of the measurements in a crude oil assay.
