Von,
I don't have a good answer to any of your questions. However, I am now at the point that I want to see data for any position. If lucas et al. wants my business, they will have to show me some data. Likewise, I know that I cannot say that most additives are harmful. So, I also cannot make negative claims against the additive companies. I don't have that data either.
I am most cautious about products that use an emotional appeal to sell. I really don't care care how many people "feel" that a product is good or bad. I am very interested in what people "think" about a product.
GreaseMonkey,
I have seen Lucas, STP, and CD-2 used in many engines, including fairly high RPM engines. I have never seen an aeration issue. On the other hand, I have seen both Lucas and STP make some fairly thick paste when used in manual transmissions. As a kid, I saw the same aeration issue with STP used in bicycle wheel bearings (I don't know why even an eight-year-old would think that STP would stay in the bearing - make an sticky mess on the floor where you park).
