The Pour Point temperature at which diesel fuel loses its fluid character and that pumps would stop operating.
12.
The sample is then cooled and then inspected for pour point as per the usual pour point method.

The sample is then cooled and then inspected for pour point as per the usual pour point method.
14.
The lowest temperature at which movement is detected on the sample surface is determined to be the pour point.
15.
The method usually gives higher pour point because the thermal history has not been cancelled by a prolonged thermal treatment.
16.
In this area we recommend that owners of above-ground oil tanks add a pour point depressant to their tanks during winter conditions.
17.
They act to reduce the formation of wax crystals in the fuel, thereby lowering the pour point and the gel point of the fuel.
18.
The oil we receive ( and deliver ) will vary greatly in its measured pour point and we never know exactly what we are getting.
19.
The oil must kept warm ( above its pour point ) in the fuel oil storage tanks to prevent the oil from congealing and becoming unpumpable.
20.
For the fuel to become pumpable again, it needs to be brought above the gel point temperature to the Ungel point, which is typically near its pour point.
