I only have my Spyder that I can talk about. I tried 3 tanks of premium and found no difference in anything, so for me a waste of money. Then after checking the research video ( by the way, I agree the first test was BS) I wonder how many manufactures are stating a higher octane just so that it looks better to the buyer? I mean, after all, "My car needs a higher octane so that means I have a better car ,,,right"? So the folks who can and want to spend more on their car so that they have something better than their neighbor now have a channel to dump the extra cash.
I really liked the fellow from Quebec, that guy is awesome for his job. Skirted around every question put to him, but sounded really good on the surface. He actually had no input into the conversation whatsoever.
Advertising today is all about what the advertiser thinks the consumer wants to hear, put in such a way that when the ad is done the consumers mind is lead to believe that what they wanted to hear was actually said,,,, when in fact, nothing was actually promised or held out as truth. But the consumer goes on their way thinking that they now know and can rely on the information they have in their head as truth.
