(Just a quick one!) High octane fuel?

[KCvale]

Hmmm... Logic tells me running Premium especially for the extra rich gas/oil ratio during break-in would be best.
It's not like we are talking a lot of money in cost per/mile.

If crappy gas and an oil mix is all you need, why not just fill-up on diesel fuel?

A very interesting comment, please elaborate on that "logic".

Yeah.....with about 95 percent of todays cars using regular gas, I avoid using premium due to the possibility of contamination from laying in the station tanks too long.

Allow me to rephrase that...
Instinct tells premium should be better, I am looking for the facts as to why it's not is all.

See above post.

Fuel grade (octane requirement) is a function of compression ratio. If the manufacture recommends a fuel with a octane rating of 87, nothing will be gained running higher octane fuel. The "logic" that if it cost more, it must be better, doesn't always work. In any event, during the break in period, the engine will have lower compression.

Because diesel fuel is not the same as crappy gas and oil mix.

Seen it, I consider the people in this community to be living it. We're pretty much doing what those "daring early pioneers" did, except our machines are a little smaller.

another point to consider, premium fuel will have less if any ethanol like someone else stated, which dries out gaskets and seals in the carburetor. We like to run premium fuel in any small engine we repair at work. (I am a small engine mechanic by trade) The EPA is even trying to make it so all gasoline sold is 15% ethanol content, but the small engine manufactures are all trying to fight that as small engines will not run right on 15% ethanol blend and the ribber diaphragms used in the carbs for fuel pumps will not hold up to it along with other issues.

When I get my 80cc 2 stroke kit, I am going to deck the head to raise compression to better match premium fuel. It will give me more bang for the buck, for little cost.
