beat me to it.zx11_12 said:Iced is correct. I work in the gasoline certification lab for a major oil company. Running higher octane than your engine calls for gains you nothing. It only costs you more. I have seen studies that say that running higher octane actually makes LESS power if you engine doesn't need it.
The one exception to this is when you are parking your bike for the winter, or for an extended time (longer than 1 month). Premium fuel will last longer without oxidizing, which is what gums up your carbs.
I have 1 bike that requires premium and 2 that require regular...that's what I run in them except for when I park them for the winter. Then I fill them up with premium and add some Sta-bil.
Because you're not risking anything by putting in lower octane gas if the bike is designed to use it. You're just wasting money (and power). As long as you're not buying cheapass gas at the local Quicky-Mart in the first place, using 87 octane in a motor designed to use 87 octane isn't going to hurt it at all.ASharpMind said:Go with premium... Why risk a 10k+ Machine?
Maybe because I don't want to ruin my bike by using fuel my bike wasn't designed to run on. And, BTW, for those of you who didn't get Eyespy's comment as sarcasm, why do we keep having the same damn subject every single week? Gas, along with what you use to clean your damn chain, along with what oil you use, along with what would be a good first bike, along with what helmet should I buy.............does the search function not work anymore?? :rolleyesASharpMind said:Go with premium...
