87 is best, even in my 'Busa which is not stock it produced more HP with 87 than 91.

A dealer once offered me some contact cleaner to clean my O-ring chain. I laughed so he offered me brake cleaner as an alternative. Guess they were out of stock on real chain cleaner! Had a discussion with his boss about that one but I don't know that there was any fallout over it.

Well CA gas is oxiginated or some ****. So it's not the same as normal 87oct. Most people have to run 91 on performance 87oct engines.

Weird, I assumed 91 was the way to go, guess I was wrong =/

Except on tour, all my gas is bought in California and I buy 89 octane. Never a ping or any other problem and certainly no reduction of power although I've never dynoed it using two different octanes. I have a stock 06.

Two things: 1) Go to another Dealer
                   2) Quit listening to the EXPERTS next door!

I use 87 and have NEVER had any problem. Remember 87 burns faster than 91, giving you better gas mileage. Besides thats what the STOCK engine was designed for

Yes CA gas does have some different additives in the mix...but you should try 87...unless you like to waste the extra $$$

 

[javie]

I'll fill up with 87 tomorrow and see the difference..

save me some$$

Search the threads, at least 100 on this subject in the past year. A lot of technical information in some of them.

RUN 87

Even when I lived in CA, I got better mileage with 87 than with 91. Octane is a measure of how fast the gas burns. The oxygenation doesn't do anything to the octane at all, if I'm not mistaken.

Yer better off with 87. However, if you have to choose between 86 and 88, go with the 88.

I tried some 87 about a week ago. I will never use it again, it was kinda bucking in the lower RPM's(under 3k)

 

[BA BUSA]

Must have been all the extra HP that you're not used to

 

[Rhythm]

Use 87 octane and 91 when the outside temp is averaging in the 90's and above.

kairles, nice pipes. She's a looker in white and silver... I like it, I like it a lot.
