Why Fully Synthetic Oil is recommended ?

 

Synthetic oil is a Lubricant consisting of chemical compound that are artificially made (synthesized). Synthetic lubricants can be manufactured using chemically modified petroleum components rather than whole crude oil, but can also be synthesized from other raw materials. Synthetic oil is used as a substitute for lubricant refined from petroleum when operating in extremes of temperature, because, in general, it provides superior mechanical and chemical properties than those found in traditional mineral oil.

 

 

Advantages

The technical advantages of synthetic motor oils include:

• Measurably better low- and high-temperature viscosity performance at service temperature extremes
• Better chemical & shear stability
• Decreased evaporative loss
• Resistance to oxidation, thermal breakdown, and oil sludge problems
• Extended drain intervals with the environmental benefit of less oil waste.
• Improved fuel economy in certain engine configurations.
• Better lubrication during extreme cold weather starts
• Longer engine life
• Superior protection against "ash" and other deposit formation in engine hot spots (in particular in turbochargers and superchargers) for less oil burnoff and reduced chances of damaging oil passageway clogging.
• Increased horsepower and torque due to less initial drag on engine
• Does not contain detergents

The Short Story

For most, here's all you need to know: Buy a brand-name oil that exactly matches your vehicle manufacturer's specifications and certification requirements, and change your oil according to the carmaker's recommendations. That will allow your engine to offer maximum performance and last as long as possible. Disastrous consequences await those who deviate from the manufacturer's recommendations. Those who want more, read on.

 

Weight and Oil Viscosity

Oil is like pancake syrup. Without blending and additives, on cool days oil would be as thick (viscous) as Mrs. Butterworth's stored in the refrigerator. At high temperature, though, it would get uselessly thin, like microwaved syrup. Long ago, the Society of Automotive Engineers (SAE) developed a rating system for oil viscosity, the most basic of characteristics, which is often called weight. It's expressed by four or five characters, such as 10W-30. The lower the number before the W (for "winter"), the better it flows in cold temperatures. The number after the dash indicates how well the oil flows when it's warm. Higher numbers mean the oil is "heavier," or more viscous. Multi-viscosity oils developed several decades ago mean you don't have to worry about using different oils for winter and summer.

Don't select heavier-than-recommended oil in the mistaken belief it'll provide better protection. Old-timers are used to heavier oils, but many manufacturers currently specify light oil, such as 5W-20. One reason is that some modern engines have incredibly tight clearances between parts. Especially when the engine is cold, a heavier oil may not reach into these tight areas. The lighter oil also helps provide better fuel economy.

 

Certifications

Quality oils carry up to three certifications from three different organizations. Your owner's manual will say which standard is required. These certifications indicate that the oil met the testing and content requirements of these organizations. The most well-known is the American Petroleum Institute's (API) "starburst" and "donut." In the center of the API circle is the SAE weight (e.g. 10W-30). The outer ring will say "API SERVICE" followed by two letters: "SM" has been the top API rating since 2004, and API says it'll work in all automotive gasoline engines. The previous standard — "SJ" — was for 2004 and earlier model years. If the service rating starts with a "C," it's for diesel engines.

American and Japanese automakers combined to create the International Lubricant Standardization and Approval Committee (ILSAC). Its current standard is GF-4. A new standard, GF-5, is scheduled for 2010. Finally, some European cars require oil certified by the European Automobile Manufacturers' Association (ACEA).

How to determine if a synthetic oil is good or bad?

 

I always hear people telling me that Mobile 1 is the gold standard in engine oil. So whats the difference between that and other fully synthetic oils?
