All the fuel here has been 10% for a few years now and it runs fine in cars and bikes. It is the small engines and older boats that have so much trouble. I abandoned Stabill in favor of Star Tron http://mystarbrite.com/startron/
a few years back and it took care of the few issues I was experiencing. Sucks to have to buy something else to put in fuel but you gotta do what you gotta do sometimes.
