Re: Interesting winter reading....
To me it seemed unbiased as he showed the additive helping and hurting various oil. It also showed the ranking of oils 1-124 or whatever. The question is, is this a valid test? I would say his results might be unbiased and correct for what he did, but is it the correct test? Is he answering a question that wasn't asked?
In other words, he's checked what is the best ford to buy, and he might have a correct list of fords by ranking, but the real question is, what is the best CAR to buy. See the difference? His list of fords is correct and unbiased, but how valid is this test in the real world.
(of course Ford IS the best car to buy but that's besides the point LOL!!)
