How is the oil made?
L’oil eating is in do contained in plant seeds. To extract it, different steps are carried out by the manufacturer. These include the cleaning and grinding of the seeds; and heating the seeds before a first pressing. This first press gives a oil raw pressure.
If your car lose oil, there may be several reasons. The most common is a leak at the seal. For example at the crankcase seal or the valve cover seal. The pump oil can also cause a leak as a result of a fault.
The oils are classified into five “API groups”. The oils belonging to groups I, II and III come from petroleum refining (mineral origin). Contrary to their detergency, their wetting power and their smoothness with respect to metals generally decreases with the group.
IV.PROPERTIES AND FEATURES OF THE OILS PJ Viscosity and pour point are the main properties. Plus one oil thicker, the higher its viscosity. Fluidity is the inverse property of viscosity. The viscosity of most fluids decreases as the temperature increases.
The consistency of an oil depends on its fatty acid composition. Indeed, saturated fatty acids are solid at ambient temperatures (20°), and melt when temperatures are above 30°. Tropical butters: Shea, Mango, Cocoa, etc. are a good illustration of this phenomenon.
Motor oil performs very important functions. It creates a film on the surface of parts to prevent wear, prevents moving parts from overheating and protects them from corrosion. It also cleans the engine. The absence of lubricant is dangerous for the latter.
In the United States, petroleum is considered an oil. It can also come from the distillation of coal or oil shale. They are traditionally used for mechanical lubrication;
no edible oil because not suitable for cosmetic use. keep the vegetable oils, and mix in the fridge. keep liniment and hydrosol away from light and heat, in the bathroom cupboard, if used daily. otherwise in the fridge.
