As for those articles,I didn't write it. Just thought it was a good way to show how marketing has played in this. For every one instance someone says theirs is better, there's always someone else stating the oposite.
For every action there is a oposite and equal re action.
Everytime a politician states a "Fact" against one, the other states a "fact" just the oposite.
LE say's their oils the best, Others will tell you the oposite.
Someone show's their oils tests are better, someone else comes out with the same test showing theirs was better.
Marketing... This is one reasn why I don't like to see testimonials and quite frankly, in house test results against other oils unless actual #'s and or details provided.
I think that I have seen more useful information come off the oil analysis as it gives a more over all concept on how an oil works in real time applications. Of course, even that varies because there is no two tests identical but you look and take all the variables into account, give it your best guess on quality, then the ultimate way to prove to yourself if its the best, is to see if it is the best for you and your application by running it in your vehicle and use oil analysis to verify you made the correct choice for yourself.
