The part about obtaining samples from the manufacturers is well taken. The part about not liking the tests because the fuel was untreated is not.
In the referenced testing, they were striving for repeatability, and in that, since you cannot guarantee what is in the treating of the fuel at the pump, the obtaining of untreated fuel is the only way to make a reasonable attempt at finding the effects of OTC additives.
The only problem I see with the Spicer study is that they didn't test my additive of choice.
MGW, if you are so sure you have the correct testing methodology, then why don't you run a series and prove it? Then we can all read your write up and critique it here on the forum, in the same cynical way so many like to Monday morning quarterback anyone's efforts at getting anything done.
Junk Science? Nope. It isn't a perfect study, but is is light years ahead of anything you guys have done.
