Pour points of lubricating oils are very low, almost always below -20°C. Particle deposition from lubricating oil is not from any process akin to ‘freezing’…

A single-grade motor oil has a viscosity which varies steeply with temperature, limiting its use to conditions where the temperature changes are such that the…

All of the oils in the have a flash point of 60°C, signifying a vapour pressure at that temperature which is not negligible. As already…

It would be difficult to assign a pour point to a heavy residual fuel oil. This is because, as already noted, it is charged with…

The terms ‘heavy fuel oils’ and ‘residual fuel oils’ are approximately synonymous. By far the main application is shipping, where in addition to purely residual…

The correlation applied to gasoline and to kerosene: 106 k/cal s-1 cm-1 °C-1 = 333 — 0.19t at 20°C and at distillation temperatures will in…

Vapour pressures of diesel at room temperature are very low; that discussed in has a vapor pressure of 0.4 mm Hg (E 0.053 kPa). That…

Lubricity is a measure of the extent to which abrasion caused by the movement of one metal surface against another is mitigated by a particular…

The conductivity of fuel is calculated for the ability of a fuel to dissipate the static electric charge. Diesel fuel is a hydrocarbon. Diesel fuel…

The absolute refractive index of a medium is the ratio of the speed of light in a vacuum to the speed of light in that…
