A great article on the effectiveness of oil additives. Be sure to read every word of it.
I'll post the conclusion below for those short on time:
The major oil companies are some of the richest, most powerful and aggressive corporations in world. They own multi- million dollar research facilities manned by some of the best chemical engineers money can hire. It is probably safe to say that any one of them has the capabilities and resources at hand in marketing, distribution, advertising, research and product development equal to 20 times that of any of the independent additive companies. It therefore stands to reason that if any of these additive products were actually capable of improving the capabilities of engine lubricants, the major oil companies would have been able to determine that and to find some way to cash in on it.
