Synthetic oil is a lubricant consisting of chemical compounds that are artificially modified or synthesised. Synthetic oil is used as a substitute for petroleum-refined oils when operating in extreme temperature, in metal stamping to provide environmental and other benefits, and to lubricate pendulum clocks .
RBOB gasoline is a blend of hydrocarbons suitable for use in Spark-ignition engines. It typically contains various additives, including oxygenates like ethanol or methyl tertiary butyl ether (MTBE), to improve octane rating and reduce air pollution. [2]
These are the detergent additives mentioned previously. To measure the alkalinity potential of a formulated oil, it is tested to obtain the equivalent amount of KOH to arrive at the oil's Total Base Number (TBN) with units of mg of KOH per gram of oil. As the additive package degrades, TBN will decrease until the motor oil needs to be replaced.
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.
So periodic oil and filter changes should still be done with synthetic oil, but some synthetic oil suppliers suggest that the intervals between oil changes can be longer, sometimes as long as 16,000–24,000 kilometres (9,900–14,900 mi) primarily due to reduced degradation by oxidation.
Synthetic crude is an intermediate product produced when an extra-heavy or unconventional oil source is upgraded into a transportable form. [1] Synthetic crude is then shipped to oil refineries where it is refined into finished products. [1] Synthetic crude may also be mixed, as a diluent, with heavy oil to create synbit. Synbit is more viscous ...
