Pretty much what it says on the topic, I got my bike a few weeks ago and wanted to know your suggestions!

 

Premium.... unless I can't find it... It's also what HD calls for...

 

Many posts on this subject, do a search of pure gas, or octane, or ethanol.

 

I use what ever my finger hits but read this article

Do you need premium fuel

 

I have an older EVO and ran Regular without a problem for several years.

It was time to do the top end last year which included higher compression.
My bike requires premium now. I may be getting more mpg though which offsets the premium cost somewhat.

 

First choice would be 93 plus but I'll run regular or E-10 if the good stuff isn't available. Hasn't hurt the bike yet and it sure beats walking.

 

I don't think premium grade will give you better gas mileage. If the engine doesn't ping on regular gas then it will probably be ok to run it. However, I put premium in mine.

 

I like to run 100LL if Im close to the hanger. If not or out traveling, I'll use the highest available.

 

I always run synthetic. Oh wait different thread!

 

I was using premium ever since I got my bike over a year ago. Just recently, about a month ago, I switched to regular. Honestly, I can't see/feel/notice any difference.
