Oil and grease can reduce the amount of friction, making it easier for parts to slide against one another, and reducing the amount of heat produced.
It's to reduce friction (and thus heat) generated while the machine's parts are moving.
The term grease is applied to many different chemicals, hence it has no specific formula. Generally, there are fatty or oily chemicals making up grease. It can refer to a lubricant, or equally well to drippings that are produced in cooking meat.
some use magnets others use lubricants such as oil and grease
a "lubricant" is a friction-reducing substance: a substance, typically oil or grease, applied to a surface to reduce friction between moving parts
Grease can be used as a noun (the object 'grease'), or as a verb (the act of applying grease to something). For example:'He applied grease to the pan to prevent food from sticking to it.''He was sure to grease the pan to prevent food from sticking to it.'
Grease is used as a conditioner on dry hooves. It keeps the hooves from drying & cracking.
Thermal grease to allow heat to transfer to the heat sink.
Industrial lubricants.
It is acceptable to load dishes and let the dish washing machine run if there is food debris or grease residue on the inside of the machine
The 3 common lubricants are grease, oil and wax. They are used to decrease the friction between touching forces. For example, in trumpet slides, slide grease is applied once in a while on the slides to make the slide easier to pull in and out.

Depends if the jacket is machine washable. If it is, try Dawn dishwashing soap. It cuts grease. Let sit on stain for about 1/2 hour and then machine wash it on hot.
