see, that's why I mean by anecdotal evidence.
I have used what the manufacturers call for in all the 30 different bikes I have owned for 53 years, most with ethanol for the last 10 years, and never had a carbon build up problem and the plugs on my CB on 87 octane 10% ethanol looked great at 25,000 miles. It now has 43,000 miles. I try hard never to waste money. It's too hard to come by in any quantity lol.
