Number 3 fuel oil was a distillate oil for burners requiring low-viscosity fuel. ASTM merged this grade into the number 2 specification, and the term has been rarely used since the mid-20th century.

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.
The octane rating of gasoline is measured in a test engine and is defined by comparison with the mixture of 2,2,4-trimethylpentane (iso-octane) and normal heptane that would have the same anti-knocking capability as the fuel under test. The percentage, by volume, of 2,2,4-trimethylpentane in that mixture is the octane number of the fuel.
Heavy crude oil has an API gravity below 22.3° (i.e., 920 to 1000 kg/m 3) Extra heavy oil has an API gravity below 10.0° (i.e., greater than 1000 kg/m 3) However, not all parties use the same grading. [9] The United States Geological Survey uses slightly different ranges. [10] Crude oil with API gravity less than 10° is referred to as extra ...
The burning of fossil fuels produces around 21.3 billion tonnes (21.3 gigatonnes) of carbon dioxide (CO 2) per year, but it is estimated that natural processes can only absorb about half of that amount, so there is a net increase of 10.65 billion tonnes of atmospheric carbon dioxide per year (one tonne of atmospheric carbon is equivalent to 44 ...
The test is important in relation to the use of additives that allow spreading the usage of winter diesel at temperatures below the cloud point. The tests according to EN 590 show that a CloudPoint of +1 °C can have a CFPP −10 °C. Current additives allow a CFPP of −20 °C to be based on diesel fuel with a CloudPoint of −7 °C.
Any reading between 20% LEL and 80% LEL in a confined space. Any reading on a pipeline operating at 30 percent specified minimum yield strength (SMYS) or greater, in a class 3 or 4 location, [clarification needed] which does not qualify as a Grade 1 leak. Any reading of 80% LEL, or greater, in gas associated sub-structures.
Previous research showed that resting energy use, or metabolic rate, didn’t change from ages 20 to 60. The new study’s findings don't contradict that. The new study’s findings don't ...
