Those additives are nothing more than snake oil.
From a previous post of mine:
"I'm glad you haven't had any problems... but know this: Back in 1992, the National Advertising Division of the Council of Better Business Bureaus asked Petrolon (Not Peleton heheh)
to discontinue such assertions (such as improved mileage, reduced wear, and just about all of their claims) due to lack of substantiating evidence. In other words... they were sued for plain out lying. Now they are more or less like those psychic hotlines. They still make lot of money, but have to advertise "for entertainment purposes only". But it has a placebo effect for some, so perhaps its worth it for that.

CONSENT ORDER TO CEASE AND DESIST</A>

--------------------------------------------------------------------------------
Part III of the proposed order prohibits respondents from representing that any Slick 50 lubricating product for use in a motor vehicle, other than an engine lubricating product, reduces wear, extends the life of a part, lowers engine temperature, reduces emissions, or increases mileage or horsepower, unless, at the time they make the representation, they possess and rely upon appropriate, competent and reliable evidence that substantiates the representation.

Sooooo... it does... absolutely positively NOTHING. At least nothing positive they are allowed to claim anymore.
My father has also worked extensively in the oil and lubrication industry, and also strongly warns against such teflon additives in oils. They can actually be detrimental in that they clog the oil filter prematurely. And the physics behind it will physically not allow the teflon to bond to the metal. I would recommend avoiding ALL oil additives from every article I've read on the subject. There is a LOT of chemical engineering that goes into these additive packages that are in a specific balance and already included in each oil. Increasing the effect of one of the additives can have a very detrimental affect on another. And most importantly remember that its the OIL THE LUBRICATES. The oil that can do this with the least additives, is the best choice.
Although this applies to slick 50 and any other name the product might be sold under, Prolong really isn't any different. If you were really into car care and knew more than you needed to, you would avoid this stuff like the plague. You owe it to yourself to research on the net for one hour to .
Slick50, Duralube, and Prolong are constantly being sued up the @ss. How could they possibly remain afloat? Well the revenue from misinformed consumers is outweighing the lawsuits so far.
Currently the manufacturers of the ProLong engine additive have been dealt a smack in the face by a Consumer Reports Magazine report into their product. CR attempted to reproduce the "no oil" test where all the oil was drained out of an engine which had been treated with ProLong, and then the engine was run. CR managed a maximum of 13 seconds running out of each of two engine before they seized up, welding the pistons to the barrels. The case is being brought to a Federal Commision for prosecution for false advertising claims. The engines come equiped with hydrolic lifters that simply won't function w/o oil. Prolong, in their tests, modified the engines to operate w/o oil in an attempt to mislead the public into believing that the engine was able to run simply on the "treatment" of Prolong. And
it has been scientifically proven that any additive that contains PTFE (Teflon) will not achieve high enough temperatures in an automotive engine to bond to metal (if your engine got that hot, you could say bye bye engine within nano-seconds). Therefore this substance is suspended in the oil and is known to prematurely clog oil filters. Dupont (one of the largest manufacturers of PTFE) published their findings against this and went on to threaten lawsuits against any of these companies that used the Teflon trademark name and refused to sell their PTFE powder to any company with the aim of using this as an engine oil additive. Unfortunately, the oil additive makers sued Dupont and the courts required Dupont prove conclusively not that PTFE would not work as an additive in automotive engines, but that it was very harmful to the engine and therefore excusable to refuse sale based on consumer safety. Dupont had no desire to invest more resources into this and consequently continued sale of PTFE to these additive companies against their wishes. This was not due to evidence proving that these additives worked or were not harmful, but instead are simply innoscent until proven guilty.
Hopefully the current lawsuits by consumer reports will amount to enough to actually put a dent in Prolong's wallet. More likely than not, they will continue selling them though, and simply have to alter their advertising campaign.
IMO uninformed consumers DESERVE what they get, but the public can't really be required to investigate EVERY little thing they purchase (like over the counter drugs for example), and therefore we need organizations to help sue these companies that are raping the less knowledgable public. But what ends up happening? Even when someone finally invests a lot of money (it costs BIG time to fight these big company's teams of lawyers) to prove these claims are total BS or harmful to the public... they just slightly change their act perhaps with a slight disclaimer. Nothing pisses me off more than those psychic hotlines for example that make totally bu****t but then at the bottom it says "for entertainment purposes only" and then its ok.
