I've put premium in two bikes that werent happy about it, Premium was the only fuel available when I was filling up and performance on both of them was awful until I'd gotten it burned off.
The CX has a few engines problems related to standing for long periods of time and exceptionally low mileage (7,000something since 1983) so I am dumping a lot of redex system cleaner through it on every fillup at the moment and she is slowly getting better.
My bike needs high octane, because the fuel tank is small if you go to a tank that doesn't have a separate hose for the different types of gas even though you order premium you may be getting enough “regular” to affect the way the engine runs. I have added octane booster because if I run a low octane fuel my engine pings like hell.
because i am a: a crazy donkey cheapskate and b: a creature of habit, i have absentmindedly grabbed the 87 octane handle (the same garbage i put in my truck) while filling up my vtx. other than suffering a bit on the mileage i didn't notice any differences. also, when filling up my earlier bikes, i always used the crap gas (poor college student) and i got years of faithful service out of them. i would try to use what the manufacturer suggests, but if that's not possible you're not going to do any permanent damage by temporarily running a lower octane fuel. if this becomes a habit, you might want to run some fuel system cleaner through it.

I think its hard to use being cheap as a reason to use cheaper gas in a motorcycle. Even now with gas prices insanely high, the most you will spend is 1.20 more unless you have a huge gas tank

True... but if the manual called for higher octane I would think there is a reason so keeping the bike it better shape/running better for 62.40 a year sounds like a deal

Hell yeh, I miss the gas mileage on my honda and being able to run low octane. My bike now gets about 45mpg and that is almost considered a gas guzzler compared to what I was getting on the Honda.
Sevulturus wrote:Indeed, mine however calls for 87 octane, and that's what she'll get. I like having the money for extra gas.
Your Buell requires high octane? Interesting. I guess that shows that compression ratio isn't the only factor determining octane requirements since the Buell has a compression ratio of 10:1 while my F4i is 12:1 and it only requires 86 octane gas.
