All,<br /><br />There are, at last count, eighteen different blends of "regular" unleaded gasoline utilized in this country. All eighteen of those are mandated by regional, federal and/or state governments.<br /><br />Arizona is a perfect example. Phoenix metro uses a different blend than outstate and is sold for an average of $.15/gallon more than outstate gasoline.<br /><br />That, in itself, is the reason for much of the distribution issues and high prices. Another growing issue is that our refinery system is stretched to bursting. We have not built a new refinery, in this country, in over fifteen years. All due to environmental issues and NIMBY's (not in my backyard syndrome).<br /><br /><br />There is NO shortage of crude. <br /><br />I realize this does not address the "octane" issue yet it does help explain why one cannot put all gasolines into the same comparison group.

So really all we have learned here, and we already knew it is that if the manufacture says minimum octain 87, The engine will run fine with 87, If it says minumum 87 better if run on 89, then run 89, There will still be no advantage to running higher than manufacture recommends. The quality of the fuel matters little, because we have no choice as we have to use what is available locally. This was about as bad as a good oil argument.

How do you think a manufacturer feels when they get down to recommending something?<br /><br />True, there are standards that must be met. Yet, I can assure you, the political standards are met long before the performance ones are.<br /><br />It has ben my experience (automotive) that engine complaints that can be attributed to fuel quality are most often regional.

I opersonnally would foloww the mfr's recommendations to the letter. Motors are too expensive not to. One thing to keep in mind for those of us who have large fuel tanks is that gas loses octane over time. You may want to consider adding some 93 octane to your tank on refuels for this. Otherwise it's a waste of money IMHO. BTW,enjoyed this "last word on octane rating".
