Octane Vs. Ethanol

Post by Tim 1956 »



I was under the confusion that the ethanol in the gas was making my 94 1500 interstate idle up and down continuously at a stop. I changed to the recreational gas and it stopped. So I thought it was because of the Ethanol. But at those prices.. yikes. I decided to try 89 octane instead of the lowest 87 octane that I normally use and it fixed the problem. It will just sit their and idle steady all the time at a stop light or whatever. Guess I rebuilt and set the floats correctly after all last year. Did not like paying the rec fuel price. But by the end of this year it will all probably be around $4 a gallon. :D

don't leave Ethanol fuel in the bike if it is not being ridden.

if you must leave it sitting for a while, use Stabil-360 in the fuel tank, run the engine long enough that you know it has the mixed fuel in the carbs.

Yes, the downfall of ethanol. :-) But I'm in south florida. It never sits more than a day or 2. Then their are hurricanes. That will be a different story. :D
Thanks.
