lol i think i just had a wtf moment seeing that

 

my bike gets 16,300 leagues per hoghead.

 

For my first post, I figured I would chime in.

Running a higher octane will not make your engine lose power. Also premium gas compared to regular gas has no extra detergents or any "extra" cleaning agents. Also, per a post on the front page, all pump grade gasolines contain 10% ethanol. Per EPA (and a few dozen other standards and authorities including SAE and ASTM), all street grades will contain 10% ethanol and 90% gasoline (unless you are running a higher ethanol fuel, i.e. e85, 90, 100).

Please advise that running a higher octane will not reduce KNOCK per se. Knock is the premature ignition of fuel due to high temperatures (a 87 octane will ignite before a 89 and so on). Knock can be, and often is, a precursor to pre ignition.

Pre ignition is the the ignition of the airfuel mixture within the cylinder by a source other than the spark from your spark plug. These points may be ring lands, valve seats, burrs on the cylinder head etc. Knock can cause pre ignition by uncontrollably raising temperatures on said parts/points.

Long story short, if you run your engine hot all the time, it wouldn't hurt to run a higher octane. If you have a ECU flash that advances/retards timing, it may also require a higher octane (possibly along with colder plugs).

Hope this helps,

Knock is not a precursor to "pre ignition"; it's the result.

I really doubt that.

 

of course! I didn't buy matching pink handlebar tassles for nothing

(I figure if nobody else was going to try to salvage this thread, I will!)

This.

 

Wow LMAO that was good

 

Once I was able to actually get to a pump (was almost hit twice) I went premium, both the other grades were plastic bagged!
