TYPES OF ANIMAL OIL

• Whale oil • Harts' horns • Drying oil • Fish oil • Shark liver oil • Tallow • Neat foot oil • Blubber

• Cod liver oil • Lanolin • Lard

WHALE OIL the oil obtained from the blubber of various

species of whales, particularly the three species of Right Whale and the Bowhead Whale prior to the modern era, as well as several other species of baleen whale.

a liquid wax and not true oil. It flows readily, is clear, and varies in color from a bright honey yellow to a dark brown, according to the condition of the blubber from which it has been extracted.

DRYING OIL is oil that hardens to a tough, solid film

after a period of exposure to air. not harden through the evaporation of

water or other solvents, but through a chemical reaction in which the components crosslink by the action of oxygen.

use has declined over the past several decades as they are replaced by alkyd resins and then other binders.

FISH OIL Oil derived from the tissues of oily fish. Sparked a lot of interest in the study

treating clinical depression and especially, bipolar disorder.

Have been limited studies done on the subject, there have been notable trials that showed significant evidence to suggest that the omega-3 fatty acids in fish oil acted as a mood stabilizer, or at least, enhanced the benefit of SSRI medications

TALLOW A rendered form of beef or mutton fat,

processed from suet. It is common for commercial tallow to

contain fat derived from other animals, such as pigs or even from plant sources. Tallow oil is used to lubricate.

NEAT FOOT OIL Oil is yellow oil rendered and purified

from the shin bones and feet (but not the hooves) of cattle.

Used as a conditioning, softening and preservative agent for leather.

Used for a blend of pure neat foot oil and non-animal oils, generally mineral or other petroleum-based oils.

BLUBBER Under the skin of whales and other

large marine mammals Used as a source of oil. Used in the manufacture of soap,

leather, and cosmetics. Used in candles as wax, and in oil

lamps as fuel.

COD LIVER OIL Nutritional supplement derived from

liver of cod fish. High levels of the omega-3 fatty acids,

EPA and DHA High levels of vitamin A and vitamin D

LANOLIN Yellow waxy substance secreted by the

sebaceous glands of wool-bearing animals.

Used by humans comes from domestic sheep.

Protect wool and skin against the ravages of climate.

Used extensively in products designed for the protection, treatment and beautification of human skin.

LARD Pig fat in both its rendered and unrendered

forms. Used in many cuisines as a cooking fat or

shortening, or as a spread similar to butter. Many contemporary cooks and bakers favor it

over other fats for select uses. Clear, colorless oil pressed from pure lard

after it has been crystallized, or grained, at 7° C (45° F) oil consisting chiefly of olein that is expressed from lard and used especially as a lubricant, cutting oil or illuminant.

RECIPROCATING LUBRICATION SYSTEM

Brake – in oil (MIL – L – 6082E & SEA J 1966)

The most used in aviationi. Grade 80 or SEA 40ii. Grade 100 or SEA 50iii. Grade 120 or SEA 60


Oil Properties


Process of straight mineral

oil Straight mineral oil are takes

from petroleum by fractional distillation process.

The produce in residue state

use to make a lubrication oil and straight

mineral oil.


History of Straight Mineral Oil

Old primary lubrication oil for aircraft. Cannot operate at high temperature. It will sludge or clog the oil strainer if it

contamination with water, fuel or lead. It still used until now for oil

consumption stability.


Break – In Time

Used on new engine for first 10 – 15 hours. Oil need to drain and replace with ashless dispersant oil. Two reason used straight mineral oil rather than ashless dispersant oil :-

1. Ashless-dispersant oil have higher film-strength. It will prevent the piston ring from rupturing the oil film and therefore the necessary abrasion on the cylinder wall will not occur.

2. It will from a glaze inside piston ring groove.


Correct grade ang high power setting of a straight air will achieve a successful break in.

High power setting mean high combustion pressure, due to piston ring design.

It will force the piston ring out to rupture the oil film.


Manufacture Nowadays, a lot of company make and

sell the straight mineral oil such as Aeroshell and Castrol.


Safety Precautions

• If the oil contact to our skin, it will plugging of sweat glands and hair follicles.

• This can lead to skin irritation or dermatitis.

• Wear something to cover your skin.

• Remove it by waterless hand cleaners follow by soap, water and soft skin brush.


Warning An empty container of it can be very dangerous. Do not drill, pressurize, cut, weld, braze, grind, flame, spark; they may explode and cause injury or death. Do not clean by yourself because it hard to remove and have toxic. Need to be dispose at safe environment.
