Lubricating the engine
The oil is the lifeblood of the engine
Do you ever wonder how the lubrication system works? Let me explain it to you…
The components of the lubrication system consist of:
- Oil pump
- Oil filter
- Oil pressure sensor
- Oil pressure indicator light
The OIL is a lubricant designed to reduce contact between two moving surfaces in order to reduce friction. The reduction of friction greatly reduces the wear of the surfaces and thus lengthens their service life. The reduction of friction also reduces the energy required for the motion. Oil serves other functions also. It serves to carry off excess heat as well as providing corrosion protection by coating parts with a protective film. The oil rating is based on two main properties: the viscosity index and flash point. The viscosity index refers to how engine temperature affects the rate at which a particular oil resists changes in its ability to flow. That is, under high temperatures, an inexpensive oil will experience rapid changes, while a good oil will resist changes in viscosity. Flash point is easier to understand, as it refers to the temperature at which oil will give off vapors when heated. A low flash point indicates that a protective film of oil on the cylinder walls will burn off sooner than a oil with a high flash point. As oil burns off cylinder walls, the engine loses protection.
The OIL PUMP is a rotary pump, located inside the engine, driven by the crankshaft at about the same RPM as the engine. The oil pump forces oil under pressure through an OIL FILTER , then various passages, channeling the oil to various moving parts. The oil pump is supplied by oil in the lower pan of the crankcase.
The OIL FILTER is designed to filter out metal shavings, carbon deposits, and dirt. The oil filter is not completely effective because it only filters a small amount of oil at a time. This cleans the oil better and doesn’t restrict the flow of oil to vital engine parts. The oil’s continued exposure to high temperatures eventually contaminates, decomposes, and loses its lubricating qualities. Also the way a car is driven affects the durability of oil. Manufacturers recommend a specific oil change interval. This is just a guideline, because the conditions that an engine is run is critical to the way an engine will last. THE HARDER YOU RUN AN ENGINE, THE MORE OFTEN YOU SHOULD HAVE THE OIL AND FILTER CHANGED.
The use of high quality oil and oil filters is essential to long engine life.
Additives to the oil are not usually effective, however I have found that a product called
PROLONG SuperLube Engine Treatment
works very well to decrease friction and improve engine efficiency of any engine with any oil.
The OIL PRESSURE SENSOR is a device monitoring oil pressure while the engine is running.
The OIL PRESSURE INDICATOR LIGHT illuminates when the oil pressure (normally about sixty PSI) drops below a preset value, usually about two to four PSI.
The oil pressure indicator light will not illuminate if the oil level is LOW. It will only come on when the oil level is EMPTY.
The oil level should be checked at least monthly to assure proper lubrication at all times.
…and that’s the way the lubrication system works!!
