It varies with the oils viscosity.
You are essentially answering your own answer within your own question. Vegetable oils and other food oils are edible oils. The other oils that cannot be eaten can be grouped into this other major category called non edible oils such as engine oils, etc.
Essential oils derived from edible foods are also edible. They may be too strong in flavor or irritating to your mouth (such as oils from hot peppers).
The pour point test determines the lowest temperature at which a substance will flow or be able to flow. This is important for understanding how a substance will behave in cold temperatures, such as in transportation and storage of petroleum products. Knowing the pour point helps prevent issues such as pipeline blockages or difficulties in starting engines in cold climates.

Floc point, also known as Freon floc point, is used to measure the performance and consistency of refrigeration oils. In order for the refrigeration system to function properly, the oil used should be compatible. Wax can separate when an oil solution is cooled with Freon. Once the wax is separated it is called flocculation and that is the reason it is called floc point.

Yes, viscous oil can freeze, but the freezing point will depend on the specific type of oil and its composition. Generally, oils with low viscosity and high pour points are more likely to freeze at lower temperatures compared to oils with higher viscosity and lower pour points.
Animal fats tend to go rancid with time. Vegetable oils will too eventually, but have a longer shelf life.
Edible oils have varying densities, so measuring by weight in kilograms provides a more accurate representation of the quantity. Additionally, weight measurements are more consistent across different types of oils compared to volume measurements in liters, which can be affected by factors such as temperature and viscosity.
