I have been worrying about gasohol for a few months, and have been carrying out some research and experimentation.

My wife put gasohol in her 1997 250 Honda rebel and it died , we had to do a total carb rebuild.

I bought several different types of fuel line and left them to soak in gasohol, some fuel line dissolved, as it reacted with the ethyl alcohol in Gasohol. Imagine what that will do to your carbs or fuel injectors.

Harley model post 1999 will run fine on gasohol.Harley says it is OK as they have prepared the fuel system to use it.

Ducati and Triumph say never use it .
Honda, yamaha Kawasaki and suzuki say do not use it.

I dont know about BMW.

If no premium 95 octane is available for my ducati i use 91 it runs OK but may require an octane booster.

Gasohol is not being promoted in europe , in fact higher octane fuels of 97 ,98 and even 99 octane are now available. In UK the lowest octane fuel is 95 octane . No 91 octane is sold.

I have used gasohol a few times in my honda shadow 1100 with no probes and seen other guys use it in a Fazers 1000 and dragstar 400 and never had any problems but I guess I will be sticking to 91 if there is no 95 avilable.
Anyone know where to buy Octane booster in Udon or Kho kaen

BKKriders have been worrying this subject to death for a while. You will have to surf for their website.
What I got from my Auto Engineering Proffesor friend at U of A is that the rubber bits in older flue systems are designed to swell in contact with hydrocarbons and they tend to absorb the alcohol , turn brittle and in some cases disintegrate. Alcohol also needs bigger jets so will tend to run slightly leaner/hotter if bike isn't rejetted. That is not usually a problem in the real world.

Gas station octane boosters are a total waste of money and will boost octane less than 0.5. Really expensive racing ones may do something but they are not available from retail outlets and are VERY expensive. Sorry did I repeat that? If you live near an airport and know the fuel guy!!!!

If you must play with octane boosting , still a waste of time, most are simply Toluene which is a main ingredient in paint thinner so available at paint shops in bulk. You have to add lots 30% to do anything.

Nissan told me that if i put Gasohol or 91 octane fuel in my new car it will void warranty 95 premium only, Honda told my mate the same for his Accord.And Mercedes Benz Pattaya have had a whole load of damaged engines from clowns putting gasohol in.

Get used to it. From Jan 1 2007 - gasohol is all you will be able to buy. That is total crap about Honda cars. They won't notice any difference.

If you take a look at
http://board.gt-rider.com/topic.asp?TOPIC_ID=1449
you will see that there is supposedly going to be a review / delay.
Personally I will believe it when it happens and to be honest I dont think it will, just like many of the proposed mega (no brain) projects.

Another little secret about gasohol they don't tell you: it causes pressurization in fuel tanks with negative vented gas caps and consequently carb problems. Alcohol evaporates at room temperature and since a gas occupies more volume than a liquid pressurization occurs. Also, I wonder what good the ethanol is doing if it evaporates before reaching the combustion chamber.
