What kind of gasoline to use on 1999 Honda CR250?
Where I live we have 3 grades of pump gas with the octane being
87/91/93. It is good to run a higher octane in your bike, however,
if you are putting the gas in your bike and then using it, 87
octane will not hurt your machine. 87 octane hurts your bike if it
sits for too long. If you plan on letting your bike sit for more
than a week, you definitely want 93 or higher. If you are going to
let it sit all winter without riding, you want to either drain the
tank and run the gas out of the carb or mix some of the STA-BIL
fuel stabilizer with your gas.
