When choosing a station to fill up, If you are like me and always run premium in bikes, look for a gas station that has a separate hose and nozzle for each grade of gas. If you buy from pumps that have only one hose for all 3 grades of gas, there is at least a gallon or so of whatever the last customer purchased in the hose between the nozzle and the mechanism that switches grades of gasoline inside of the pump. This being said....The first gallon or so that comes out of the nozzle is most likely going to be the low grade stuff. Therefore you will not be putting very much premium into your 2.6 gallon tank. Look for stations that have a separate hose for premium.

Your Rebel was designed for running on regular gas. Why pay more, unless is is alcohol-free gasoline?

Yep. My understanding is that there is absolutely no advantage to using premium gas. It may run hotter and damage the pistons.

Premium (high octane) does not run hotter, burn slower or produce any more power.
Octane is only to raise the point of heat ignition. Spark is spark. Once sparked, they burn the same speed and the same temperature.

That's 91 RON (research octane number) or 86 PON (pump octane number)
In the United States, the fuel is graded by PON.
86 PON is all that is required.

I expect ethanol content has more to do with choosing higher octane gases. At least here in New Brunswick, there are some vendors who sell ethanol-free 'hi-test'. I use it in chainsaws, rototiller, snow blower, outboard motor, weedwhacker, and motorcycles.
Before the advent of 'corngas', I used nothing but regular.
Our government has issued a caution about using ethanol-laden gas in smaller engines and older vehicles of all kinds.
Given the role that ethanol content plays in reducing gas mileage, it MAY be that use of ethanol-free higher octane gas will increase your gas mileage.

Here in AZ, alcohol gas is all that is available, in any grade. Alcohol will definitely cause damage to your fuel system, and lower both your power and mileage. The U.S. EPA does not care about your engine. The Rebel actually runs best on low octane. It has low compression and a very small bore. Using premium will reduce power and eventually result in carbon buildup in the combustion chamber, plugs, valves, and in the exhaust.

Gasoline will burn, but will NOT explode out in the open. It is gasoline vapor in a confined area that explodes. Spilling it all over your tank will ruin your paint eventually. And at todays prices it is a waste of money. I fill up all my bikes while sitting on them, I just pull up to the pump, pop the cap, insert the debit or credit card, and fill it up. You can get more in the Rebel that way than having it parked on the sidestand.

If you have a CA Rebel, the best thing you can do for it is to remove the evap cannister, throw it in the nearest trash can, and vent the tank directly to the atmosphere. You won't have any more problems.

Some stations have gas nozzles that are either full on or off. These can be really messy trying to fill up a motorcycle tank. I have actually carried a bicycle water bottle with me for use when I run into one of those. I fill the tank as close to full as I can without splashing gas all over, then put gas in the plastic bottle and use that to finish filling the tank.

Fortunately I have never had to use reserve on the Rebel, and only 3-4 times in my whole life. I always fill the tank up before it gets that low, and if I have any doubts about their being a station within range, I carry extra gas with me.

Bummer, Jerry. One wonders how a state can decide that no one will sell gas that is safe for lawnmowers, outboards and old cars.
At one of the stations I frequent, they clearly indicate that the regular has 10% ethanol, the high octane has 0% ethanol, and the 'blended' or midgrade is, of course, 5%.

Drool!

That's "premium" that's worth buying!

It isn't a single state. There has been a mandate that all grades of fuel be sold as 10 percent ethanol. I think it goes in to full effect starting the new year.

It'll be the same here soon, until one day somebody wakes up and asks why we're doing this when it makes no economic or environmental sense whatsoever.

seems my bike I fill up every 100 miles. not really sure what my mph is. It just seems like a good easy number to remember and not get stuck some where. not even sure who big a stock tank is. never got to the reserve to even see what or how far it would go..
