How Your Vehicle’s Lubrication System Works

How The Lubrication System Works In An Engine?

Lubrication System
 
The engine is the heart of your vehicle. Hundreds of moving parts within the engine must be lubricated. While the engine burns gasoline, it also takes in air from the outside. Thousands of gallons of air are brought into the engine for every gallon of gasoline consumed. Road dust and dirt are brought in with this air. While most of the air is cleaned, some dirt and dust may get by the air filter. In addition, incomplete combustion adds carbon deposits to the oil. Water can also come in contact with the oil from humidity in the air and from gaskets leaking. All of these factors can lead to engine oil failure. Engine oil is the substance that keeps your engine going day after day. It is extremely important to keep the oil clean and at the correct level to prevent engine oil failure.
 
 
 

Purpose of Oil in the Lubricating System

 
Without oil an engine would not run. Engine oil is processed from crude oil and is specially formulated to do four main tasks within the engine:

  • Lubricate
  • Cool
  • Clean
  • Seal

Although recommended oil change intervals vary by vehicle manufacturer, in general, a good rule of thumb to follow is to change conventional motor oil every 3,000 to 5,000 miles. “If you’re using full synthetic oil, we recommend going about 7,500 between changes.

 

Synthetic oil vs. conventional oil

Synthetic oil is exactly what it sounds like: an engine lubricant created artificially from chemical compounds. Some classes of synthetic oil start with conventional oil as a base that’s then chemically altered to produce synthetic oil, while others may be artificially created from other raw materials. In contrast, conventional motor oil (also referred to as standard oil or mineral-based oil), is refined from naturally occurring crude oil.

Expert mechanics say synthetic oil does offer specific advantages over conventional motor oil.

With synthetic, the oil’s ability to do its job within the car engine is superior to mineral-based oil.

The primary purposes of synthetic oils are to reduce engine wear during cold start-up and drive-away, and to avoid or reduce oil degradation.

In a nutshell, synthetic oil is thinner, resists temperature extremes better and generally lasts longer. You likely won’t notice any difference in how your car performs, but the durability characteristic is the most important from a car owner’s perspective, as it translates to less frequent oil changes compared to conventional motor oil.

The fundamental difference is that synthetic oil can go longer before it starts to break down when compared to conventional oil.

Why oil changes are important

Considering that an oil change can cost about as much or less than a full tank of gasoline for many drivers, they’re a relatively cheap investment to prolong the life of your vehicle.

Oil service is the most important thing you can do for your car. “Preventive maintenance doesn’t cost money, it saves you money.”

And whether you use conventional motor oil or synthetic, regular oil changes by a qualified mechanic can help ensure longer life for all your car’s mechanicals.

Whatever oil you use, someone has to check under the hood from time to time to avoid serious surprises.

 

Engine Oil Lubricates

The most important function that engine oil does is to lubricate. Within the engine there are hundreds of little parts rubbing up against each other. This rubbing creates friction. Friction is the force that resists motion between two bodies in contact. Engine oil molecules are like little ball bearings. The oil molecules have a tendency to stick to metal surfaces, but have less of a tendency to stick to each other. Oil decreases resistance and friction between two sliding bodies, resulting in a reduction of engine wear.

Trouble Guide
** Excessive Oil Consumption

  • Broken or worn piston rings
  • Worn valve guides or seals
  • Improper oil viscosity

 

Engine Oil Cools

While engine oil does reduce friction, it obviously cannot eliminate it. Without engine oil, friction would build up undesirable heat, causing the engine to overheat, damaging internal components. Engine oil is pumped throughout the engine, moving into various parts and then back to the oil pan. In the oil pan or through an engine oil cooler, heat is dissipated to the outside air. Engine oil helps cool your engine in this process.

 

Engine Oil Cleans

 

The internal combustion engine is not very efficient (only about 28 cents of every dollar spent on fuel results in moving the vehicle). This inefficiency causes unburned deposits to build up within the engine. Some dirty air may also come in through the air filter during the intake process. While the engine oil is lubricating all the critical engine components, it also cleans by removing particles of carbon and dirt. As the oil is pumped throughout the engine, the dirty particles are screened out by the oil filter. Clean engine components help insure proper lubrication.

Engine Oil Seals

 

During engine operation, the pistons are rapidly moving up and down. Engine oil is also moving up and down with the pistons. Not only does engine oil lubricate, cool, and clean; it also seals between vital components. Engine oil seals between pistons and the cylinder walls to reduce blow-by. Blow-by is the gas that escapes past the piston rings and into the crankcase. Engine oil acts as a seal between components that are separated by gaskets. For example, you should put a thin film of oil on the oil filter gasket before installation to seal the connection between the filter and engine.

Overfilling Oil ?


If one is good then two is better, right? Not always. Engine oil contains detergents to help clean particles and other materials in the engine, similar to soap in a washing machine. If you overfill your engine oil, you will get air bubbles. Air does not have much of a lubricating ability. And adding too much oil can increase oil pressure causing failure to various seals and gaskets.

 

Understanding Oil Ratings
Reading an oil bottle can be very confusing. The three main ratings you need to become familiar with are:

  • SAE – Society of Automotive Engineers
  • API – American Petroleum Institute
  • Energy Conserving

Conventional and synthetic oils begin in the ground. But that’s where the similarities end.

Synthetic oil is not only refined but also distilled, purified and broken down into its basic molecules. This process not only removes more impurities from the crude oil but also enables individual molecules in the oil to be tailored to the demands of modern engines. These customized molecules provide higher levels of protection and performance than conventional oils. But the synthetic base oil is only half the story. The correct blend additives must go into the mix to create the oil.
