There premium 91 octane says 100% ethanol free, but it looks like it has 10% methanol. I think that's just as bad on small engines, carbs, lines, etc..

Confirming that they still carry ethanol free in 91 octane.

I drive a 2000 Geo Metro, non ethanol makes a world of difference on performance and economy. I fill up once a week here, have not had any issues.

This is at the Sinclair station where Highway JJ (east of Mexico) meets 54. Only Octane 91 is Ethanol free. Just found out and confirmed this today (722/14).
