I have been running 92 octane I was wondering how the 2006's run with 87 octane?

 

Owners manual says 91 or higher, and since 91 is as high as I can get, that's what I run. Even run some octane boost about every 3 tanks...call me ****.

92 is pretty good, I have 91 in my area. Anyone else have higher?

 

This has been coming up a lot lately in the General section and even threads in here that started off differently. I've basically said the same thing before and I know there are a lot of people that totally disagree with me, but air cooled engines that run hot are more prone to detonation and the higher octane reduces the risk of this.

I'll bet many are running 87 in their '06s without any problems. But there are just too many factors for anyone to say that it is safe to run 87 octane in YOUR bike. Did you do a stage 1? With or without a remap? Dyno tuned? What octane was in the tank when it was tuned? Do you run in Alaska or Arizona? Do you never go wide open throttle or do it all the time?

I live in Florida and the heat is an issue nearly year-round. And I like to run it hard sometimes, so I'm going to run 92 or 93. I wouldn't say you have to do that, just trying to mention some of the reasons why the higher octane *might* be better, and IS safer in my opinion.

I know a lot of people think it's an unnecessary waste. But here is the other thing to consider. I'll probably average about 5000 miles per year (work at home). At 30 cents per gallon difference between the cheapest and the best (it's actually less than that here), with the mileage I'm getting now (44mpg), that's only like $34 for the year. That's hardly a tough decision in my book even if I rode twice as much.

I use 93 it's the highest available in my town.

 

say no to 87 octane, and try to stay away from those pumps with only one nozzle because if the last person used 87 octane before you arrived at the pump then you still have 87 octane in the gas hose. It will flush into your tank along with the higher octane fuel. Maybe there is not much difference, but normally I try to pull up to a pump with 3 hoses.

 

Yep, quite a few stations around me have 93 as premium. Only a couple have 91.

 

The factory says to run 91 or higher. 93 is availiable here, and that's what I run.

 

You guys are lucky! I would love to use 93, and I don't care paying extra for it, even with todays prices.
