The performance benefits of aftermarket additives are mostly unsubstantiated.
AMSOIL has long discouraged motorists from using any kind of aftermarket lubricant additive. After all, AMSOIL synthetic lubricants use the finest quality synthetic basestocks and additive systems. AMSOIL's response to the question "Should aftermarket additives or aftermarket products be added to AMSOIL motor oils?" is " No, you don't need them. AMSOIL motor oils are formulated under the strictest quality control standards to provide superior lubrication performance. Additives cost money and only detract from the quality of AMSOIL motor oils." Additionally, not only do they detract from the quality of the motor oil, but they can also be damaging to your engine.
A perfect example of why AMSOIL discourages use of aftermarket additives is the Federal Trade Commission's (FTC) recent lawsuits against many auto additives, seeking to halt false and misleading advertising and gain refunds for customers who purchased the products. According to the FTC, the enhanced performance benefits claimed by many additivess provide are totally unsubstantiated, and in the same tests cited to support performance claims, motor oil treated with additives actually produced more than twice as much bearing corrosion than motor oil by itself.
The CRC L38 test is a standard auto industry test which measures the bearing corrosion protection properties of motor oils. According to the complaint, in early 1997 an independent testing facility performed two CRC L38 tests of the popular additives. The results showed motor oil treated with additives produced more than double the bearing corrosion as motor oil alone. According to the FTC, the defendants eliminated the bearing corrosion results, as well as all other negative results, to produce one "report" from the two sets of tests, using this "report" in its infomercials and on its website.
The FTC charge alleges that the additives did not possess and rely on reasonable substantiation from the following product claims:
increases gas mileage by a minimum of 10%, reduces engine wear, reduces or eliminates engine wear at startup, reduces engine corrosion, extends engine life and reduces emissions.
The FTC also alleges that the defendants falsely represent that the results of the CRC L38 test prove:
increases gas mileage, reduces engine wear, extends engine life, lowers fuel consumption by 8.5%, lowers wear on valve stems by 66%, lowers wear on piston skirts by 60% and cuts carbon build-up on valve stems by 66%
Finally, the FTC charges that the additives do not have substantiation for the representation that the testimonials and endorsements shown in advertising are "the actual and current opinions, findings, beliefs, and/or experiences of those consumers; and typical or ordinary experience of members of the public who use the product."
The lawsuits a long line of FTC charges against auto several additive manufacturers. The FTC has previously halted allegedly deceptive advertising by the marketers of Dura Lube, Motor Up, Prolong, Valvoline, Slick 50, STP and other major brands of engine treatment systems.

As of date, there is not a single charge against AMSOIL's claims by the FTC.
Here is my opinion (not only is it my opinion but it is my opinion backed by proven scientific research and testing by some of the worlds best chemists and engineers):
Stay away from all aftermarket additives!
You can't necessarily improve an oil by putting in more
additives. In fact, you can make things worse. For example,
sulphur compounds have antiwear, antioxidation characteristics,
but they can reduce fuel economy and affect catalytic
converter operation. Too much of a particular detergent
could affect the antiwear balance. Too much of a specific
dispersant could affect catalyst performance and reduce
fuel economy. Antiwear and friction-reducing additives
also may have ingredients (such as sulphur) that could
affect catalyst performance.
You simply do not need them and you surely don't need the problems they may cause with your engine. If your still not convinced then think about this statement:
The major oil companies, including AMSOIL, are staffed with the, bar none, some of the best chemists, scientists and engineers the world has to offer. Now, don't you think that if they determined that their motor oil was lacking an additive that they would blend it in their additive package? They obviously have the technology and resources and the financial backing to do it. Then why don't they? The answer is simple: They are not needed!
How can it be that some fly by night additive manufacturer can have a miracle, cure-all additive without knowing the chemistry of the oil it will be used in? The answer is, they don't. They simply are out to get your money by using false and deceptive advertising to appeal to your desire to have what they are selling in your engine. They are masters at marketing, not science chemistry and engineering and I would equate them to nothing more than snake oil companies. Thank goodness for the FTC that is actually doing what it is supposed to be doing; protecting the consumer and going after these companies and hopefully put them out of business!
