I have a 2010 Electra-Glide classic. I am going to Denver Colorado. I have been told that the octane levels in the gas are below manufactures recommendation of premium or 91+ octane. Do I need to add a booster to the fuel for the higher octane

 

Wouldn't hurt. Suggest Lucas

 

 

I used to run Moroso Octane booster in a street car that had a compression ratio of 13.5:1. It contained a chemical named Methylcyclopentadienyl manganese tricarbonyl (MMT). I used it in concentrations higher than recommended and it left a redish substance on the plugs, enough that I bought a small spark plug cleaner/sandblaster to clean them.

I'm not sure how octane boosters react with catalytic converters. Maybe check on that before using it.

 

The less air density at higher elevations lowers you CR a little so less octane should be required, that being said almost all of the larger stations have 91 octane gas.

 

Out in South Dakota, when I was there a couple times for Sturgis, it's sometimes hard to find gas above 89 octane. It all worked fine in my bike, but it's a 96 not 103. Fuel mileage sucked, however.

 

I never had any issues finding 91 on a recent trip to Colorado. I always carry some octane boost with me when touring. My Glide doesn't like it when the temps get above 90-100F and needs it even with high octane fuel.

 

I have 10.5:1 compression in my 103 and have ridden it over 70,000 miles all over this country. I always try to use the highest octane available wherever I am and have never had any problems with any low octane fuel anywhere.

I think octane booster is a joke. Read the label. All claims I have read is if you put in the recommended amount, it will raise the octane .1. That's one tenth a point, not one point. I admit I haven't researched octane booster very much because I have never for one second thought I needed an octane boost.

The only time I have suffered for high octane is the 1st 100 miles into Canada from Ste Suit Marie.
Make sure you gas up in the states or after the first 1oo miles in Canada, which i think is around Thunder Bay...cant remeber so dont hold me to it.

 

You should be fine with whatever gas you use.

H-D realizes we don't sometimes follow the recommend fuel they want us to use or is not available when you need to gas up, so they managed to include various sensors that compensate for that.
