2. Synthetic oil - Wikipedia

   en.wikipedia.org/wiki/Synthetic_oil

   Aircraft jet engines, for example, require the use of synthetic oils, whereas aircraft piston engines do not. [3] Synthetic oils are also used in metal stamping to provide environmental and other benefits when compared to conventional petroleum and animal-fat based products. [4] These products are also referred to as "non-oil" or "oil free".

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. Shell Rotella - Wikipedia

   en.wikipedia.org/wiki/Shell_Rotella

   The line includes engine oils, gear oils and coolants. The oil carries both the American Petroleum Institute (API) diesel "C" rating as well as the API gasoline engine "S" rating. Ratings differ based on the oil. Rotella oils, like the T3 15W-40, meet both the API CJ-4 and SM specifications, and may be used in both gasoline and diesel engines.

5. Diesel fuel - Wikipedia

   en.wikipedia.org/wiki/Diesel_fuel

   A tank of diesel fuel on a truck. Diesel fuel, also called diesel oil, heavy oil (historically) or simply diesel, is any liquid fuel specifically designed for use in a diesel engine, a type of internal combustion engine in which fuel ignition takes place without a spark as a result of compression of the inlet air and then injection of fuel.

6. Synthetic fuel - Wikipedia

   en.wikipedia.org/wiki/Synthetic_fuel

   The fuels produced by the various synthetic fuels process also have a wide range of potential environmental performance, though they tend to be very uniform based on the type of synthetic fuels process used (i.e. the tailpipe emissions characteristics of Fischer–Tropsch diesel tend to be the same, though their lifecycle greenhouse gas ...

7. Diesel engine - Wikipedia

   en.wikipedia.org/wiki/Diesel_engine

   1952 Shell Oil film showing the development of the diesel engine from 1877. The diesel engine, named after the German engineer Rudolf Diesel, is an internal combustion engine in which ignition of the fuel is caused by the elevated temperature of the air in the cylinder due to mechanical compression; thus, the diesel engine is called a compression-ignition engine (CI engine).
