Regular, Mid-grade, or Premium fuel?

With stock engine (pistons, cams, carburetor), is the best choice to use Regular gas? If not, what advantage has another grade over it?
My engine spec compression is 8.9 to 1, whatever that means. Whatever does that mean, anyway?

It won't hurt anything to run premium. My bike never ran right on 87 octane, I think 89 is OK, but higher than that isn't necessary.daveo wrote: Is it a waste of fuel (and money, of course), if not needed for good combustion? And, if the compression ratio doesn't warrant using Premium, doesn't some unburned fuel blow out the exhaust, and carbon-up the spark plugs?

8.9:1 compression - Is this a Harley or an old Kaw that needs a ring job? :laugh: My KZ650-C1 is 9.5:1. Ed
