Your posts make it apparent that blenders who've signed on (payed the "entrance fee") to be included as "Top Tier" certified gasoline providers only have to meet gub'mnt standards to stay in that elitist club. I wouldn't, doubt, though, that most or all who've done so squirt a little more additive in the mix than minimally required to assure that spot checks won't uncover a "miscalculation". But, even the companies that aren't licensed as "Top Tier" providers also have to at least meet minimal gub'mnt standards - and may also surpass them by a small margin for the same reason. Conclusion?
 
Marketing, marketing, marketing - aka, "psychology"...
 
If drivers stick with national brands from stations with high turnover, they probably have nothing to worry about regarding gasoline quality, "Top Tier" certification notwithstanding.

...this premise perseveres when tanking up my AV6 6M coupe with RON 87..............and at 22.5k with fresh oil and a new filter...........I still marvel how well she pulls on good old 'regular' gas..........
 
...great car...

Sure about "RON" (Research Octane Number) 87? What's posted on the pumps is the Pump Octane Number - 4 pts. lower than RON. In other words Pump Octane Number 87 (unleaded regular) is equal to Research Octane Number 91. (RON 87 would be virtually U.S. non-existent pump octane 83.) I used Pump Octane Number 91 unleaded premium ONCE as an experiment and noticed no difference in startability, tractability, or fuel economy. For all the good the extra $3.44 spent did, I might just as well have tossed the money down a storm drain. Nothin' but unleaded regular since.

"There was an old wive's tale, which has never bee substanitated, that a Honda design engineer said that you could gain 10 more horsepower by burning premium instead of regular. But it is just that and has never been substantiated or proven for Honda Accord V6 engines."
 
I realize I'm a little late to this discussion, but here is the substantiation: http://www.usatoday.com/money/autos/reviews/2002-08-01-accord_x.htm
 
"The Accord V-6 ratings assume regular-grade fuel, and Honda will market it as a regular-fuel engine. But — pssst — it's good for another 10 hp and 10-plus lbs.-ft. on premium, acknowledges V-6 engineer Asaki."

I've heard this. But I have also heard that it will take a couple of tanks for the computer to adjust to premium gas. And if you burn just one tank of regular gas, you are back to square one. So if you want to run premium fuel (for the power gain) you have to continue using premium all the time. I'll stick with regular, 240 horses are enough for me.

No offense to you personally intended, but in my opinion Honda engineer Asaki's old wife would be better advised getting her tail in the kitchen to prepare a light repast of saki and sushi for honorable husband-san after a hard day at the test track. I'm also skeptical about a whole ten hp. - more likely on the order of about half that where the rubber meets the asphalt unless intake and exhaust modifications are undertaken for improved inflow and extraction at speed. I'll also disagree with my buddy elroy5 on a minor point. Nearly instant information from the knock sensors will allow the ECM to advance or retard ignition timing within two crankshaft revolutions to adjust for a change in pumped fuel octane - and the little buggers continue doing so on the fly whenever the engine's operating. (Knock sensors - the greatest advance in engine control technology since sliced bread and trade whiskey. )

Certainly no offense taken at all.
 
However:
 
1. In a case of choosing to believe a Honda engineer being quoted in a national newspaper over some random dude on some car forum? I don't know about you, but I'll believe the Honda engineer.
 
2. That said, 5 HP, 10 HP, whatever. Neither one is anything to brag about, and neither one is going to be noticeable in every day driving. Me? I use regular in my V-6.
 
3. I was just pointing out that this "mythical" 10 HP that, whether you choose to believe it or not, does have a real Honda source and is not, in fact, something someone just made up like some people on here would lead you to believe.
