He he, well, that's the way it goes. Realistically, a lot of additives have a long and storied history. Some may have never been worth a hoot. Some might have been more useful with various older technologies, including older oils, leaded fuel, carbs, and so forth.
rdalek: This has nothing to do with opinion. Science isn't dictated by the FTC or courts. I know what the Planck constant is, I know the value of pi, and the speed of light, and I don't care if the Supreme Court of both our countries disagree - it's not a matter of opinion.
I've had vehicles last hundreds of thousands of miles, with many going to the wrecker with perfectly fine running engines. So, I can't think of any additive that would help on that front. Engines of that vintage in my usage were also clean internally, so I didn't need an additive to help with that (and that's even more obvious with today's oils). The only thing left would be an additive that would save enough fuel to offset its price, and that's essentially impossible to measure outside of a laboratory setting, so once again, I'm not interested. I can't tell the difference between a heavy 40 and a light 30 in fuel consumption, so I can't see an additive making a difference, either.

As opposed to a non-testable hypothesis?
