On the other hand, the gel point of crude oil is dependent upon the composition of the crude oil as some crude oils contain more or less components that dissolve the paraffins. In some cases the gel point of a crude oil may be correlated from the pour point. [1] [2] The gel points of some common petroleum products are as follows:
It is defined as the minimum temperature in which the oil has the ability to pour down from a beaker. [1] [2] In crude oil a high pour point is generally associated with a high paraffin content, typically found in crude deriving from a larger proportion of plant material. That type of crude oil is mainly derived from a kerogen Type III.

Most often, mineral oil is a liquid obtained from refining crude oil to make gasoline and other petroleum products. Mineral oils used for lubrication are known specifically as base oils . More generally, mineral oil is a transparent , colorless oil, composed mainly of alkanes [ 2 ] and cycloalkanes , related to petroleum jelly .
The aniline point measure of the ability of the base oil to act as a solvent and is determined from the temperature at which equal volumes of aniline and the base stock are soluble High aniline points (approximately 100°C or greater) imply a paraffinic base stock, while low aniline points (less than 100°C) imply a naphthenic or aromatic stock.
In crude or heavy oils, cloud point is synonymous with wax appearance temperature (WAT) and wax precipitation temperature (WPT). The cloud point of a nonionic surfactant or glycol solution is the temperature at which the mixture starts to phase-separate, and two phases appear, thus becoming cloudy.
Melting points (in blue) and boiling points (in pink) of the first eight carboxylic acids (°C). For most substances, melting and freezing points are approximately equal. For example, the melting and freezing points of mercury is 234.32 kelvins (−38.83 °C; −37.89 °F). [2]
