What Fuel for 79 GS1000?

[Guest]

In the midwest U.S. the superunleaded at the pump is an ethanol (alcohol) blended gasoline and typically rated at 89 octane.
Do any of you use this in your old GS's I've stayed away from the alcohol blends up to this point for my bike's but run it in all my autos since it is cheaper and higher octane.

I cant recall the last gas pump I've seen that did not say, "contains up to 10% ethanol".

I'm sure in some locals that is appropriate, since I believe the gas gets mixed somewhat. Here in Ne. The pump choices are 87 octane unleaded and 89 octane super-unleaded w ethanol.
I don't use the ethanol blend as I didn't know how the old bike would react. Octain, it sounds like a safe bet you use the ethanol blended product with no ill effects? Is there a noteable performance increase with the 89 octane?

Never tried it in the Suzuki. Although I have tried it in my Toyota Pre-Runner and the only thing I notice is a bit better milage.

I've noticed lately - past year+ - that if anything I'm riding/driving has been acting oddly (fuel related) that I had just been to a Shell station. I'm not trying to knock Shell because I had always defended them but then fuels came up on another Mfr forum and after multiple people commented on Shell, I started to pay attention. Point being... maybe you steer clear of Shell till you're happy with how she behaves in general so as to not perceive a problem where there might not be one. Otherwise, as stated before, start low and increase as conditions require.
