By using the term "fluid" rather than "oil," they hoped to discourage the previously accepted practice of using SAE 20 engine oil. This fluid was composed of a Group 1 base oil and additives to reduce oxidation, foaming, rust, corrosion, varnish, and sludge buildup. This was the world's first automatic transmission fluid, designed for the world ...
Most modern cars are built with organic acid technology (OAT) antifreeze (e.g., DEX-COOL [25]), or with a hybrid organic acid technology (HOAT) formulation (e.g., Zerex G-05), [26] both of which are claimed to have an extended service life of five years or 240,000 km (150,000 mi). DEX-COOL specifically has caused controversy.
Usually, it is coloured red or green to differentiate it from motor oil and other fluids in the vehicle. This fluid is designed to meet the unique demands of an automatic transmission. It is formulated to ensure smooth valve operation, minimize brake band friction, facilitate torque converter function, and provide effective gear lubrication.
Murphy oil pressure gauges with switches that activate on low pressure. Oil pressure is an important factor in the longevity of most internal combustion engines. [1] With a forced lubrication system (invented by Frederick Lanchester), oil is picked up by a positive displacement oil pump and forced through oil galleries (passageways) into bearings, such as the main bearings, big end bearings ...
Oil does not degrade significantly just sitting in a cold engine. On the other hand, if a car is driven just for very short distances, the oil will not fully heat up, and it will accumulate contaminants such as water, due to lack of sufficient heat to boil off the water. Oil in this condition, just sitting in an engine, can cause problems.

Oil cooling is the use of engine oil as a coolant, typically to remove surplus heat from an internal combustion engine. The hot engine transfers heat to the oil which then usually passes through a heat-exchanger, typically a type of radiator known as an oil cooler. The cooled oil flows back into the hot object to cool it continuously.
An adjustable pressure regulator ensures that the oil pressure is kept stable at different engine speeds. The dry-sump system requires at least two pumps - one pressure and one scavenge - and sometimes as many as four or five scavenge pumps are used to minimize the amount of oil in the engine.
