I always use  , will 87 hurt ? Probably not , however many say and have had problems with low octane being dirty , so its one of those things . take the chance or just go with a higher octane. Lower octane doesn't equal "dirty", lower octane is usually more pure than higher octane, higher octane usually has alcohol and other stuff (like detergents, stabilizers and the likes) added to the mix, alcohol is not good for our scoots since it can cause backfires, dirty piston cams, higher operational temperatures and premature components failure (like valves). Interesting reading here: www.nicoclub.com/archives/gasoline-octane-myths.htmlMost of the fuels here no matter what octane have all the additives and ethanol. Also the higher octane burns hotter which can help lower the build up caused by these fuels. |

Rather than take advice from "certified mechanics" (certified by who?), why not do a little research? How about taking some advice from the US Federal Trade Commission: www.consumer.ftc.gov/articles/0210-paying-premium-high-octane-gasolineExcerpts: What are octane ratings? Octane ratings measure a gasoline's ability to resist engine knock — a rattling or pinging sound that results from premature ignition of the compressed fuel-air mixture in one or more cylinders. What's the right octane level for your car (vehicle)? Check your owner's manual. Regular octane is recommended for most cars. However, some cars with high compression engines, like sports cars and certain luxury cars, need mid-grade or premium gasoline to prevent knocking. Will higher octane gasoline clean your engine better? No, as a rule, high octane gasoline doesn’t outperform regular octane in preventing engine deposits from forming, in removing them, or in cleaning your car's engine. In fact, the U.S. Environmental Protection Agency requires that all octane grades of all brands of gasoline contain engine cleaning detergent additives to protect against the build-up of harmful levels of engine deposits during the expected life of your car. Should you ever switch to a higher octane gasoline? A few car engines may knock or ping even if you use the recommended octane. If this happens, try switching to the next highest octane grade. In many cases, switching to the mid-grade or premium-grade gasoline will eliminate the knock. If the knocking or pinging continues after one or two fill-ups, you may need a tune-up or some other repair. After that work is done, go back to the lowest octane grade at which your engine runs without knocking. Bottom line: Scooters, even those with a BBK, are not high compression engines. I have never heard a scooter engine with octane related knocks or pings. All gasoline is required by the EPA to have cleaning agents regardless of the octane rating. Using high octane in your scooter will do nothing but make you spend a bit more money. If you do use it, fine, if you normally use it and get lower octane by accident, also fine. The only thing you may want to search for in your attempts to fill up is gasoline with no ethanol mixed in, it can gum up your carb if allowed to sit for a while. |

Quoted from your link: "Unfortunately, this is where the myth of what gasoline’s octane rating really means creeps into the picture. Time and again, people will be told that high octane fuel burns cleaner or more completely, and that it will give them extra power and better fuel mileage than Regular octane gasoline because it contains more ‘energy.’ These blanket statements are simply not true. In fact, the octane rating for gasoline has nothing to do with the amount of power locked inside of it – it actually relates to just how much a fuel can be compressed before igniting. The higher the number, the less likely it is to ignite under pressure." |

I've said this in almost every " octane " thread . many experts say higher octane is better and many say it doesn't make a difference . I've rarely heard anyone say lower octane is actually better. So which do u believe ? No one here has ever done any lab tests on the difference in octanes so we are left to choose . I'd rather go with the higher octane , its a win win choice. I've had my scoot for nearly 4,yrs . the previous owner used nothing but 87 . when I got the scoot it was running like " u know what " so I took the carb apart cleaned it " yes it was dirty " but it never ran right until I bought a new carb . I have yet to have any issues with the carb even having the slightest bit of build up in it. Also let 87 sit in your tank over the cold months and see what happens . I have also never had gum up over the cold months it has sat with the fuel in the tank . there are other +'s with then just everyday use. |

Somebody give the man a cigar, we have a winner. Scooter engines's compression is no where enough for preiginition of a lower grade octane level. I would guess the higher gease gas may even be older than lower grade gas from customer demand. |

Thanks jerry , I have done my own research on octanes . there are more sides then just what u posted . alley always makes it an argument , however I said over and over I'm not saying that i know this to be a fact . its a choice between two sides . no big deal . alley just likes to argue , its just in his blood . his blood pressure must be through the roof.

The main thing to remember is that higher octane burns hotter , therefore the hotter it burns the more contaminants are burned away. This can be backed with physics but how much of an impact will it have ? |

Hey lain , even if lower octane will not make a difference in performance or cleanliness , remember I have yet heard of anyone getting bad gas while filling up with , and if you end up leaving the scoot sit for a few months , octane will last longer in the tank . so your choice buddy. |
