I also only use Regular US 87 with 10% ethanol and no problems in 30k miles.

In regards to ethanol in premium, especially in the middle of the country (corn country).  Unless specifically posted as ethanol free you should assume there is ethanol in all grades of gasoline rather than the other way.

Near me we have a few (can count on one hand) the number of stations that have any ethanol free gas.  It is sold at premium prices.  I do my last fill-up with that if winter is going to be long (more than a month) and I won't be riding at all.  So typically in late December I fill with that, stabilizer, and let her sit full on tender.  But here in KC, winter is really Jan/Feb and sometimes isn't that bad.

Exactly my method but I'm at just over 10K miles.  For those interested, and in the USA, you can go to https://www.pure-gas.org/ and see if there might be any stations selling alcohol free pumps.

BTW, When I filled my Concours up Sunday morning at a Mobil station, just east of the US-131 Post Drive exit north of Grand Rapids, under the Premium button it said 93 octane and "Contains No Ethanol".

Hi All,

I live in western Canada and from day one have run with 87 octane (R+M/2) with no issues other than saving lots of money over my 87000 kms  :046:

best regards,

I also run 'mid-grade' due to pinging under load. Rarely does it with the 89 octane mid-grade
