My dealer said to use 91 or at least 89 octane in my 883 Sportster and HD manual calls for 87 "regular".

i've been running 87 as i'm cheap and no problems, knocking etc.

 

QT Hush,

I think different models of HD's require different octane ratings depending on their compression ratio. The 2005 XL1200R Sportster manual says to use 91 octane, what bike have you got?

ronn39,

I believe MTBE being replaced by ethanol was a federal mandate. They finally listened to the mountains of evidence that MTBE was destroying our water supply...

(From the 2005 Owners Manual):

The 883's run 8.9-1 compression, and the minimum recommended fuel is 87 octane (91 RON).

The 1200's are running 9.7-1 compression, and minumum recommended fuel is 91 octane (95 RON).

And speaking of gasoline blends, especially Methanol....

From the Manual:

"Do not use gasoline that contains methanol. Doing so can result in fuel system component failure, engine damage and or equipment malfunction. (001148a)."

 

I am sure my manul calls for 91 or better octane and I try to run that usually 93 .Some stations only carry 89 ( CASEYS) and my mileage drops 2mpg with t.his gas

 

When I puchased my bike, the guy told me to try & run at least 96 octane because of the high compression. The highest we have in town is 91, so I bought some of those little octane packets from the local Harley dealer. I think they're called Rocket Fuel. & cost $1.60 each. 1 packet treats 2.5 to 5 gallons of gas.

 

I have a 2001 fuel injected Electra Glide Classic.

 

So what do you guys think of me putting 100 octane into my 2006 1200 Low?


What would be the advantages and disadvantages?

 

got my first oil change schedualed for next Wed. (bad case of **** glacoma commin on here - (can't see my **** goin to work) so will be callin in sick) - slightly over the 1000 mile mark @ close to 1300 miles but had the blessing of the dealer to keep ridin as long as I kept her under 1500 miles and 200 mph

Will mention and give them this topic but the bottom line amounts to about .80c per tank full at whatever price the pump is stealing (currently 3.05 for 87, 3.25 for 92 octane) - not sure savin a buck is woth the worry, if it is possible, might set a buck aside with every fill up as a chrome account

 

Manual says 93 so I'll be sticking to that. Just had the dealer crack open the engine to replace some stuff and no "skidmarks" were found. And that was 54k+ miles of 93 octane. Kinda doubting that article.
