Grade Of Fuel Poll

Marten · Apr 26th, 2009, 07:49 AM

I use 91 , its the highest here, Sunoco has 93 our dealer says Sunoco blends Ethenol to get it to 93 and not to use it. I have tried it seems fine. I try and run the highest available.

Now I am confused ( doesn't take much ) my manual says up to 10% ethanol is ok up to 10% methanol is not ok. My question, is the manual incorrect and I should stay away from 10% ethanol. I can get 94 octane with ethanol or only 91 without where I am.

Here in Canada they have mandated the Ethanol mix,so I have been running Sunoco ultra 94,at least they state it on their pumps.and it gives me an octane rating 3 higher then Shell or the others.JMO

i was getting a little pinking on the bob after the 103 upgrade (running 10.5 compratio) so i have upped the fuel to 99 and the pinking has more or less gone away, once i start tweaking the map i may be able to get back onto the cheaper stuff at 92

I use Shell 93 whenever possible. Suppose to have something that keeps the valves and pistons cleaner. Hope it's true

I run a couple gallons of 110 through my softtail about once a month. Eliminates any chance of pinging, but you can't beat the smell of running 110.

I mix it with 92.

Even though my clymer manual says 87 is norm I run high test. Every Harley rider I have asked says to run high test because it is best for Harleys.
