The whole purpose of my initial post was to inform everyone of my experiece, nothing more nothing less. I wasn't trying to claim top prize in a science fair and I don't get commission from the oil companies for getting people to switch to a higher octane gas. If you don't think what I reporting is true, perfectly fine with me. I don't feel the need to try to win votes in my favour... to be honest, I could care less.

Just to clarify, I should have used "bias" not "faith" in my reply. I'm basing my experience from the 2 fill-ups with the TCH and multiple times with my previous car. I'm not a "car guy" so I don't know much about the inner working of an engine, and don't have a bias either way re. higher octane = higher performance and economy.

 

I think I need to clarify my comments re. boost in power. To be honest, I don't think the power difference is enough to result changes in the 0-60 times. However, there is definitely an overall sense of power/stabilty (maybe the correct word is torque) when accelerating and maintaining that speed.

 

I have a suggestion. Since a few of you have bought ScanGauges, it might be worth using them to characterize engine behavior on various fuel grades. One of the instantaneous readouts on the SG is spark advance, which varies depending on what the knock sensors tell the ECU. My recommendation would be to use that readout while running through a tank of regular fuel and get an idea of what the spark advance looks like under a variety of conditions. (It does jump around depending on what the car is doing.) Then run through a tank or two of higher octane fuel and see what happens. Increased spark advance on high octane fuel would be an indication that the car is having trouble on regular.

I did this experiment a couple of weeks ago and came to the conclusion that higher octane ratings don't help me. YMMV.

 

leepark, I think the phrase is "couldn't care less". This is the least you can care. "could care less", leaves room for less careing. Your welcome.

 

Since when was this a grammar class? This isn't the first time I overlooked grammar and selling prior to posting, and I'm sure it won't be the last. Are you going to edit all my posts? What's your email? I'll email all my future posts (and work documents) for you to edit prior to submitting. Thanks in advance, I really needed an editor. Next time I make a wish I'll wish I was as perfect as you... you're my hero!

 

Leepark, Don't sweat the small stuff, all forums have what they call the web police that have nothing better to do than critizise spelling or grammer (sick people) lol. sum peeple yust hav 2 mutch tyme!!!

 

BTW, I think you should get an editor yourself. WTF is "careing"? If you look careful, you can find numerous mistakes (punkuation, gramehr, ...) in your reply... I thought you were PERFEKT!

 

Steve, I am sorry this offended you; it wasn't my intention to make you look bad. Enough has been said already by others regarding my first post, but this one comment tells me you really didn't understand what I meant. I have no better ability to override my human abilities than you or anyone else. There is zero reason to assume that my "trying it" would result in any better data than the report on which I was originally commenting. If I tried it, and then found the premium fuel did, or did not feel more powerful, my opinion, too, would still be a wholly untrustworthy opinion.

My reason for posting was not to criticize you, but to inform you and the many participants here who share your most common misunderstanding of this human condition. We all make better judgments when we recognize what evidence is useful and what evidence is not. It has nothing to do with smarts, or honesty, or character, etc., but everything to do with understanding a most significant frailty of the human mind, and knowing when to distrust yourself because of it. In its most basic form: humans easily recognize patterns where none exist.

If we're going to be picky then it's caring, not careing. Take 2 points off for spelling. By the way, you're welcome, not your welcome.

 

And there's the buzzer. Tie score. Back to the newsroom. Today's topic: power and octane. Perhaps we should wait to see what Bigfoot finds since I believe he is conducting some in-depth trials with the TCH and higher octane fuel. https://www.greenhybrid.com/discuss/...tch.10733.html
