Can I run 87 octane or do I need 89 or 91 in a 2008 vulcan classic 900?

ditto...

you don't gain much by spending the extra duckets... you're better off running regular and every do often running a cleaner through it. my local dealer offers a bottle for $9 and lasts for like 10 fill ups (or something close to that)... it's like your cars injector cleaners just for our bikes.

octane required

Back in the spring when I joined the forum I was scolded by not doing a search before making a new thread. As you will see this was a hot topic back then too. Looks like most posters back in the spring think you should follow the owners manual recommendation?

I have never been able to establish a whit of difference between any grade. Some suggest premium is a bad thing.

I wondered the same thing, and for a few years ran 93 octane. A few months ago, I saw a few threads about octane and switched to the regular 87. Since switching to regular grade, I have noticed a slight increase in fuel economy. I wouldn't say this is a definitive, permanent change. I've done a few trips on the regular gas and less commuting. But I can say that I have not seen any ill effects of going with regular gas.

For what it's worth, I'm riding an 07 900 classic that I run on 10w-40 dino oil.

+1.
Gas is expensive enough. Use "regular".
I HAVE to use 92+ in my Harley - and it SUX.

Read the pump. When I rode down through Utah, I saw alot of 85 octane regular there. I bought the lowest grade that was 87 or higher octane, which was usually the middle grade, as I recall.

I've heard some say that at higher altitudes you don't need as high an octane rating, but I wasn't in an experimenting mood, being 1000 miles from home.
