Who runs premium?

[EMTkid]

tarzana boy - I think this whole topic is splitting hairs for sure, but a lot of it is dispelling myths about fuel and hype etc. As far as higher octane running better in a properly tuned engine, the properly tuned part doesn't really make a difference unless the "tuning" affects the compression ratio. A fuel/air mixture will sometimes combust before the proper time (ie spark) because of the compression spontaneously igniting the mixture. In a gs there simply is not enough compression to get the 87 octane to burst prematurely. As far as late combustion, that really can't happen as long as you have a properly timed functioning spark plug, in which case it doesn't have anything to do with the fuel.

Oh, and premium is more refined than regular...by nature refined means purified and premium fuel is more pure (octane) than regular...by a small margin, but it is still a little further up the chain chemically speaking.

The history channel actually has a really neat program about the history of gasoline, i think it was a Modern Marvel...I dunno, maybe someone else has seen it? Very simplified explanation into great detail of what is was and how its evolved into the refined forms we have today.

"Paduan" over at Beginnerbikers.org, worked for a refinery and this was his take on premium versus regular:

"Regular" gas is often reformed or cracked, which means that the molecules have been modified forcibly. This grade is often unstable, and causes the fuel system problems people incur with "stale" gas.

I have a chemistry minor, and as that statement stands, it's .

"Paduan" over at Beginnerbikers.org also said:

There is always a certain percentage of water in all gasolines. THats where that little drip from your pipes comes from. Guess which blend has the most?

I don't have a chemistry minor, but in high school chemistry class we learned that the byproducts of hydrocarbon combustion are primarily carbon dioxide and water (in addition to heat, of course).  That's where that little drip from your pipes comes from.  "Paduan" over at Beginnerbikers.org is a dumbass trying to sound smarter and more important than he his.  Don't base anything you do on the opinions of dumbasses, especially when it's your money.

I run premium, and use silk scarves to clean up my oil spills.

I also enjoy lighting very expensive cubans with hundred dollar bills.

I don't think I've posted in this octane thread yet...

I run mid-grade in my Ford Exploder because it sucks ass and needs the extra cleaners they put in the gas...  If I run cheap gas, it runs like total ass and my check engine light comes on.  Don't ask me why, it just does.  :dunno:  I've taken it to 4 different mechanics and they all fix it the same way...  Clean the fuel system...  Then it runs great for a while and with cheap gas...  Same problem...  So, I run mid-grade and haven't had the problem in over two years.

In my GS, I've tried cheap gas, mid-grade, and super...  I swear it pulls a little harder on super...  So, I run super.  Yes, it's probably all in my head but the extra $0.80 a tank is worth a healthy head.

I always put the cheapest gas I can find in my wife's Hyundai... Arco, generic, whatever...  And it always runs great.  

So...  Screw your science, books, and lectures...  I'm going off of non-scientific largely-flawed personal-experience with-hyphens. :nana:

You, my friend... are a pauper.

I never light my own cigars.  Instead, I have one of my Oxford educated PhD servants use one of my $1,000 federal treasury bonds as kindling to light one dozen of the finest Andorran cigars that I keep in my titanium-reinforced cherry humidor.  After I arrive in the smoking room on my solid platinum Segway, I choose the lit cigar with the best aroma, and have the rest extinguished with Evian spring water.  

I rather dislike the smokey smell in the smoking room, so after I have finished my cigar I have all of the leather+maple furniture replaced, along with the egyptian cotton window treatments.

I find that the texture of $100 bills suits it more for use as toilet paper.  I pay a team of seamstresses to stitch $100 bills together as 2-ply toilet paper for nature's inevitable call.

Octane is resistance to detonation.

I think some one does not like me.  B) xx(

I guess a lot of people think it is better for the engine for whatever reason.  Few days ago I was riding with my dad (I have GSE he has naked Goldwing) and we stopped at the gas station becuase we needed fuel; he said imma pump the good sh*t; which was premium gas.

Sometimes i buy octane booster from walmart, and when i treat it with my gas it seems like when I power shift it into second, my shocks jump up a lot higher than without it.  Dunno it could be all mental.

I think it's all in your head...
I don't think it matters much with a carb'd bike, but I know that with some fuel injected bikes they clearly advise AGAINST octane boosters as these as the engines/fuel systems are not designed to run on super high octane fuels (although I don't know how much boost you are giving it... ).
