What gas/additives do you guys use?

Manual says 87 or higher. That's what I've been using.

With such a small tank though, it's not like switching to a higher grade is going to add much cost like it would with a car, so I'm thinking of upgrading.

Do any of you guys use 89 or even 93?

Is there any benefit to it? Long or short term?

On top of this...do you guys ever use any additives when you fill up? Like STP Gas Treatment, fuel stabilizer, fuel injector/system cleaner? Anything like that?

I gained about 3-4mpg by switching up to 91-93 octane. Also all of the Triumph tunes recommend 91oct or higher...

I run 91, although I'm not sure there's any benefit. I don't fill it up THAT much, so I go with premium.

I use Sta-Bil with a full tank for winter storage and it has always emerged from hibernation with zero evidence that it was sitting that long. Nothing. Always happy about that.

I might run a little Sea-foam through every second or third tank. Just because...

I use the mid-grade of gasoline, Stabil over the winter or if I go away for more than two weeks, and a carb cleaner (Prestone, I think) for a few tankfuls at the beginning, middle and end of the season. I have no idea if any of this does any good, but I'm sure that it does no harm.

I run 91 octane in both of my motorcycles here in Colorado...anything lower than 91 octane my fuel mileage and performance drops off. Haven't had to use a stabilzer in the winter months as my bikes get ridden and never sit for more than a week or 2 at the most even in the winter.

I run the cheapest fermented goat pee I can find. Every few months I dump in a can of Genuine Snake Oil.

I don't live in a "store my bike" state. That would be the ONLY reason to add stuff to the gas, or the oil for that matter. What does your owners manual say? Of course octane has been beaten to death. Just remember that octane, like gallons are not the same in every country.

Damned Dirty Biker!

Manual just says 87 or higher.

My gas light also comes on around 100 miles. I can't remember what the manual said of how many miles to the tank, but I think it was around 180, no?

If the light comes on with under a gallon left, I'd be getting around 50mpg. So maybe it was 140, not 180 miles per tank.

Another gas thread. :-0
Someday there won't be any fuel, then what we talk about batteries?
Just stirring up the conversation.
