Default Fuel Question

Due to some health issues I won't be able to ride for a few weeks. I have the bike on a battery tender but was wondering if I need to put some fuel stabilizer in the tank or not? If so, what brand would you use?
Thanks in advance...and BTW..Happy Thanksgiving to all....

How many is a few weeks? Gas with the 10% ethanol can start to break down in as little as 3 weeks. If your looking at 2-3 than I wouldn't worry about it but any longer I would put in some sta-bil.

I have left my bike sit with a full tank for 3 months and it fires right up and never had a problem. A few weeks will not be a problem

Yeah a few weeks is not an issue, but if a few months then I would add some Seafoam to the tank. I use Seaform for winter storage and it stabilizes the fuel and also cleans the injectors.

I don't think a few weeks will be a problem. A few months and I would use something just to be safe.

Is this a problem for fuel injected bikes or just carbs? I had heard in the past that the breakdown will not harm FI.

Default Never use it

Never use it. Long as it does not sit over 4-5 months it will be OK. My bike seldom sits over a few months but my riding lawn mower sits 5 months and all I do is try to make sure tank is below half to add fresh gas. If I do not catch it does not appear to hurt anything even with the new gas with 10% ethanol. Been doing it this way 40+ years and I do all my own work. Think I know what I am talking about. My 12HP Sears mower was used in 1989 when I got it. Kept a 69 Firebird 10 year sitting till my son and I restored it and it did not hurt carb. Still ran when we got to it. Hope you are filling well soon.

These days, fuel has so many additives and stabilizers and cleaners in it....I don't bother anymore. Versus 20-30 years ago...fuel would "go bad" over a period of time. Even with my boats..which I winterize, I just top off the tank. In the spring..fire right up just fine.

I think Stonecats right but I think one of the biggest things that has helped is that especially your CA bike has a completely sealed system that only allows air in when running and prevents the gas from evaporating. I've see bad gas that has set open in a jar and it gets thick.

Gas is better now than it was 20 years ago, but it still breaks down over time.

If it's going to be more than 3 or 4 weeks before you will be able to burn up most of the the old fuel and refill with fresh gas then you should use a stabilizer.

I prefer SeaFoam or Stabil. Add it to the tank, fill up, and then let the bike run at least 5 minutes before storing it.
