Yes, the factory fluid is synthetic. An often overlooked fact by the snake oil pushers.

I appreciate the fact that someone actually has posted a link to some very good info on synthetic ATF. However, do you you realize there are many different Base stocks to make the
synthetics from.
1-Polyalphaolefins (PAO's)
2-Synthetic Esters
a. Dibasic Acid Esters (Diesters)
b. Polyol Esters
c. Phosphated Esters
3-Polyalkylene Glycols (PAG's)
4-Silicones.
And lastly,
Hydrocracked oil, which is a Highly refined petroleum product.
This last one (Hydrocracked oil) was allowed to be used as a "Base Stock" to make a "SYNTHETIC" lubricant due to a court battle between Mobil and Castrol. This occurred in 1999, when Mobil took Castrol to court claiming on TV the Castrol "Syntec" was not a synthetic, as they were using a hydrocracked petroleum to make their synthetic oils from, and still charging the higher prices for their synthetic, versus the PAO based Synthetics on the market at the time.
The ruling released in April of 1999, stated the National Advertising Division (NAD) addressed complaints filed by Mobil Oil Corp. regarding the truthfulness of Castrol North America Inc. 's claim that its Syntec provides "superior engine protection" to ALL other motor oils, both synthetic and conventional, and Syntec's esters provide "unique molecular bonding". Mobil charged that the advertisements inaccurately represented that the current formulation of Syntec is Synthetic. The challenge was filled based on statements castrol made in a series of Television Commercials, Web site publications, package labels and brocures.
The bottom line was Mobil lost the case, as the court ruled their advertising was OK, as the SAE had determined earlier that any oil made through the process of sever cracking, and reforming processes may be
marketed as "Synthetic"
Each of the above
base stocks have differing characteristics, some very excellent. Some not so good.
There are also 5 levels of oil additive packages that the oil Companies can use or purchase to put in their products to complete the overall product. The highest level of these is 5 times more expensive than the lowest!
There are seven common oil additive families.
1-Anti-wear agents: These help to minimize metal-to-metal contact by chemically forming a film on metal surfaces to help reduce engine cylinder and piston ring wear.
2-Corrosion inhibitors: They help to prevent chemical attack from contaminants formed in the lubricant during the combustion process.
3-Detergent and Dispersants: These chemically neutralize acid contaminants in the oil before they become insoluble and form sludge. Particles are kept finely divided so they remain dispersed and suspended in the oil.
4-Foam inhibitors: These cause small bubbles to combine into larger bubbles that burst more easily therefore reducing foaming, which reduces lubrication.
5-Oxidation inhibitors: These help to lengthen oil life by reducing oil oxidation, which increases oil viscosity.
6-Rust inhibitors: These chemicals protect iron and steel engine parts from rusting due to water contamination. Heating and cooling of engine parts and lubricants leads to condensation and water formation.
7-Viscosity index improvers: These help oils to flow better, particularly when cold. And when the engine and lubricants are hot, they “thicken” oil so it adheres to internal surfaces better.
Now how about price!
If you have a large Company that has "Stock Holders", they want higher profits from their investments. So the oil Company's with Stock holders will formulate their oils to the lowest cost, that will still meet the requirements set forth by the API and the SAE, which I might add are MINIMUM requirements. Example: a $. 89 cent quart of oil can meet the minimum requirements!
To Amsoil's defence, they are a private family owned Company, and do not have stock holders, so they can put the dollars into their products, and still have a competitive price, but have a much better and superior product!
As far as I know, they are the only Oil Company that will warranty their oils for up to 35,000 miles or 1 year which ever occurs first, and have done for over 30 years! Do you know of any others?
Best regards,
