Explained - Synthetic Vs. Conventional
Ok, Here is a collection of information I have put together on the subject of Motor Oil, Mainly, Why bother to spend the extra sometimes 400% cost for a quart of oil. 
Definitions to start with.
"Oil", a suspension of minerals that are separated from crude oil in the cracking tower. The Crude is heated to different temperatures and then removed, graded, filtered and packaged by characteristic.
"Synthetic Oil", A Completely man made lubricant. It has no natural waxes and is usually made to a much higher tolerance than regular oil.
What Do The Numbers Mean?
On every bottle of motor oil there is a seal that gives you three pieces of information:
* The API service rating
* The viscosity grade
* "Energy Conserving" indicator (it either is or it isn't)
The API service rating is a two-letter rating that tells you the type of engine the oil is meant for (gasoline or diesel) and the quality level.
The viscosity grade (for example, 5W-30) tells you the oil's thickness, or viscosity. A thin oil has a lower number and flows more easily, while thick oils have a higher number and are more resistant to flow. Water has a very low viscosity -- it is thin and flows easily. Honey has a very high viscosity -- it is thick and gooey.
The standard unit used to measure viscosity is the centistoke (cSt). According to the Automotive and Industrial Lubricants Glossary of Terms:
Viscosity is ordinarily expressed in terms of the time required for a standard quantity of the fluid at a certain temperature to flow through a standard orifice. The higher the value, the more viscous the fluid. Since viscosity varies inversely with temperature, its value is meaningless unless accompanied by the temperature at which it is determined. With petroleum oils, viscosity is now commonly reported in centistokes (cSt), measured at either 40°C or 100 °C (ASTM Method D445 - Kinematic Viscosity).
The centistoke rating is converted into the SAE weight designation using a chart like the one shown on the Superior Lubricants Web site.
Multi-Weight Oils (such as 10W-30) are a new invention made possible by adding polymers to oil. The polymers allow the oil to have different weights at different temperatures. The first number indicates the viscosity of the oil at a cold temperature, while the second number indicates the viscosity at operating temperature. This page from the Sci.Electronics.Repair FAQ offers the following very interesting description of how the polymers work:
At cold temperatures, the polymers are coiled up and allow the oil to flow as their low numbers indicate. As the oil warms up, the polymers begin to unwind into long chains that prevent the oil from thinning as much as it normally would. The result is that at 100 degrees C, the oil has thinned only as much as the higher viscosity number indicates. Another way of looking at multi-vis oils is to think of a 20W-50 as a 20 weight oil that will not thin more than a 50 weight would when hot.
This is why some companies choose to offer Single Weight Oil for Racing. The Royal Purple Synthetic that I run has a weight of 30W, they offer multi weight oil such as 05W30 and 10W30, but the single weight oil gives a more consistent oil. This is only recommended for cars that require this level of thought such as a motor designed to run at much higher HP than the original design permitted. It is not recommended to change the oil rating just because... You should research your oil requirements based on precise calculations or stick with the OEM recommendations..
Ok,
Why Pay the Extra money?
Basically, unless you need it, you don't have to pay. As long as your Oil meet the basic OEM requirements, Bob's your Father's Dog. Your Precious Warranty will fix any problems you might have. Hell, Millions of people have and will continue to run Conventional Oil.
End Of Discussion...
Now, for the rest of us who thing that good is not acceptable and want excellent... Enter the Synthetic. Right off the bat you are paying at least double the cost by volume. Why... The cost of R&D and the materials themselves. You are getting a better product.
All oils have a point of breakdown, as oil is heated it will still lubricate metal on metal contact and cool the parts as well. This is the point of having it there to begin with. So regular oil, regular driving, regular engine. No problem.
Synthetic oil has a much higher tolerance for chemical breakdown. Basically, it will continue to lubricate under harsher conditions.
It has the added feature of not Gelling in the winter. Conventional oils have suspended waxes in them that are natural. If you were to freeze 1 L of Conventional Oil and a MOBIL 1 down to -40 Deg and then pour them out, the Conventional Oil will run like cold honey. The Synthetic will pour almost as well as when it was warm. So cold starts in the winter... The oil is pumping much faster during those critical first second. The start is also easier because the oil pump isn't being forced to pump Gel through your filter.

AMSOIL INC. set out to examine the specifics of the overly broad Nothing Outperforms... Mobil claim. AMSOIL 5W-30 Synthetic Motor Oil (ASL) and Mobil 1 SuperSyn 5W-30 Motor Oil were analyzed in five key bench tests measuring motor oil performance: NOACK volatility, flash/fire point, pour point, four ball wear and total base number (TBN). As shown in the charts below, AMSOIL outperformed Mobil 1 in all five areas
NOACK Volatility
The NOACK Volatility Test determines the evaporation loss of lubricants in high-temperature service. The more motor oils vaporize, the thicker and heavier they become, contributing to poor circulation, reduced fuel economy, increased oil consumption and excessive wear and emissions. A maximum of 15 percent evaporation loss is allowable to meet the API SL and ILSAC GF-3 specifications. As shown in the graph, AMSOIL 5W-30 Synthetic Motor Oil lost an extremely low 4.9 percent of its original weight during high-temperature service, maintaining its superior protective and performance qualities,while Mobil 1 SuperSyn 5W-30 Motor Oil lost 9.17 percent of its original weight.
Four Ball Wear
The Four Ball Wear Test determines the wear protection properties of a lubricant by measuring the wear scars produced by four metal ***** in sliding contact under the test parameters. The smaller the average wear scar, the better the wear protection provided by the lubricant. As shown in the graph, AMSOIL 5W-30 Synthetic Motor Oil completed the Four Ball Wear Test producing a smaller wear scar than the Mobil 1 SuperSyn 5W-30 Motor Oil.
Flash/Fire Point
The Flash/Fire Point Test determines the lowest temperatures at which application of a flame will cause lubricant vapors to ignite (flash point) and sustain burning for five seconds (fire point). Lubricants with higher flash and fire points exhibit more stable volatility characteristics and are safer to use and transport. As shown in the graph, AMSOIL 5W-30 Synthetic Motor Oil has higher flash and fire points than does Mobil 1 SuperSyn 5W-30 Motor Oil.
Pour Point
The Pour Point Test determines the lowest temperature at which a lubricant flows.The lower a lubricants pour point,the better protection it provides in low-temperature service.As shown in the graph, AMSOIL 5W-30 Synthetic Motor Oil has a lower pour point than Mobil 1 SuperSyn 5W-30 Motor Oil.
Total Base Number
Total Base Number (TBN) is the measurement of a lubricants reserve alkalinity. The higher a motor oils TBN, the more effective it is in handling contaminants and reducing the corrosive effects of acids for an extended period of time. As shown in the graph, AMSOIL 5W-30 Synthetic Motor Oil has a higher TBN than Mobil 1 SuperSyn 5W-30 Motor Oil.
Our lineup of Mobil 1 Extended Performance high-endurance motor oils includes a 5W-30 grade, which is the viscosity most recommended by car builders over the last 10 years. This viscosity is recommended for most General Motors vehicles and many imports. The 5W-30 is a good viscosity for a broad range of applications and climates.
All Mobil 1 Extended Performance viscosity grades have been tested to be fully compatible with engine seals and conventional oils. A special oil filter is not required.
Mobil 1 Extended Performance motor oil is designed for today's longer service intervals. Mobil 1 Extended Performance products contain 50 percent more SuperSyn, 37 percent more cleaning agents, and 36 percent more anti-wear additives than Mobil 1. Mobil 1 Extended Performance with the Advanced SuperSyn System helps keep engines running like new and helps extend engine life by reducing wear and oil breakdown. Please follow the recommendations in your owner's manual while your car is under warranty.

Oh BABY, Now We Talking...
http://www.royalpurple.com/
This is the tech-sheet for it. There have been independant studies that have found all their claims are true. It was designed by a "Chemical Enginer" who's specialty was industrial lubricant" It's his lifes work and quite remarkable. Basically. The Metal Protection is off the scale and the breakdown point is also off the scale. At $9.00 per L it's the most expensive, but who cares if it saves your motor how much it is...
Royal Purple strives to produce lubricants that provide the highest level of performance available on the market today. Because Royal Purple's sole focus is to create state-of-the-art lubricants it develops products that significantly outperform in laboratory settings and more importantly, in the field.
Many view lubricants as a commodity, where low price and service issues dominate purchasing decisions. Therefore, oil companies seeking large market share have a great incentive to keep manufacturing costs low and little incentive to dispel the myth and upgrade the quality of their lubricants.
Royal Purple, however, recognizes that lubricants are not commodities. Reliable equipment operation critically depends upon the quality of the lubricant used. Lubricant performance directly and significantly affects how long, how reliable, how efficient and at what cost (i.e. parts, labor, downtime, number of oil changes and energy costs) your equipment will operate. For instance, lubrication-related failures account for 54 percent of all bearing failures.
The key to Royal Purple's ability to outperform leading synthetic-based and mineral-based oils is SynerlecŽ, the cornerstone of Royal Purple's entire line of products. SynerlecŽ is Royal Purple's proprietary, lubricant additive technology that strengthens the oil film to provide extra protection and performance.
Summary of Customer Benefits:
High Film Strength
Royal Purple's lubricants are up to 700 percent stronger than other synthetic oils.
Reduced wear and downtime.
Improved equipment life and reliability.
Lower operating temperatures.
Reduced part replacement.
Reduced bearing and equipment vibrations.
Reduced maintenance costs.
Longer Oil Life
Royal Purple's lubricants last up to 400 percent longer than other synthetic oils.
Outstanding Corrosion Protection
Royal Purple's lubricants provide greater protection than traditional circulating and EP oils.
Uniquely combines both high film strength and outstanding rust and corrosion protection into one oil.
Excellent Demulsibility.
Royal Purple's lubricants save equipment and oil changes by rapidly and completely separating from water.
Proprietary additive technologies protect in wet environments by displacing harmful water from metal surfaces.
Rapidly and completely separates from water and does not emulsify with water.
High Cleanliness.
Royal Purple's bearing and hydraulic oils are typically 200 times cleaner than conventional lubricants delivered in steel drums or by bulk delivery.
It occurred to us that we've yet to run a test with Royal PurpleŽ oil that didn't result in a power gainit might be a marginal gain (as with our little Acura Integra), but it's a gain. We've also torn down some of our dyno engines that have been seriously abused, but with Royal P in the pan, the bearings have looked new. So consider this an approval of the company's line of synthetic lubricants with SynerlecŽ. We also like the spray lubricant, and while we can't document any improvements thanks to synthetic wheel-bearing grease, it makes us feel like we're doing the right thing when we pack bearings with that stuff, too. David Freiburger, Hot Rod Magazine

This time it's a quest for torque. Luckily, we got horsepower as a bonus...Royal Purple bought us 7 hp and 10 lb-ft. Combined with the extra engine protection and heat resistance, this is a no-brainer.
Engine Masters
For the third year running, Royal PurpleŽ synthetic motor oil was the oil of choice for the winner of the Popular Hot Rodding Engine Masters Challenge. This years 3rd annual competition saw 50 engine builders vying for up to $100,000with the top three finishers all using Royal Purple products.
Holy ****, With that kind of testamony, why would you run anything but...

I read the thread where a guy was trying to trash you about your f/i info and I wanted to kick his ass. even if someone were to use opinions as well as facts, that's what I come here for. At least you sound more educated than some of the losers I see posting unestablished nonsense. I know this thread was purely informational, but I just wanted to say Brian MP5T rocks

Thanks for the compliment.
Just so we are clear on this thread.
You Probably noticed my writing style in the first post as it was written by me,
I would like to be able to claim all the second and third "Belt Fed Statisitcal ****" but I'm sure that you all saw that they were taken directly from the 4 Oil Companys Web sites. The Intro to Royal Purple was me but the rest was them.
I posted the additional information from the web sites to give you all some idea about what the manufacturer is saying about their product.
The Forced Induction 101 thread was all writen by me unless specified in the thread.
I don't care if someone has a problem with what I say. If it's proven to be wrong, I will change it. I just can't stand negativity and hostility for no reason. Act like a human and we all seem to be able to work through it, Insult and Bitch, and Humans tend to take a Defensive and Hostile stance. It's counterproductive. Respect. We are here to discuss and learn. Even if a couple people have a problem with the way I explain or my opinion, there are some others who learn from it and are happy, so I continue to do it...

Brian, awesome job man. You are a great help to this community with helpful and useful information.
Correct me if i'am wrong but I think I remember reading somewhere in this org that someone took apart an engine that used Royal Purple for a couple years or something and then once the engine was taken apart all the parts were purple because of the oil. Any truth to that?

Of all the synthetic oils you posted data-sheets on ONLY the Mobil 1 (basic formulation NOT the "extended" mileage version) currently meets the GM4718M standard neccessary for maintaining the warranty coverage on the LSJ.
Others that meet the GM4718M standard include the Texaco Havoline Synthetic and Chevron Supreme Synthetic.
Using ANYTHING ELSE has the potential to void your engine warranty
