Re: Regular v premium
Read and heed this man's post. It is more conformation to what I've been saying every time this subject comes up. This not only applies to our little bicycle engines but to your daily driver. Running high octane, or 'premium' fuel above what the auto maker recommends will be a benefit, but only to the folks making and selling it to you. You and your stock engine will not see any advantage.
