Some adjustments to ignition timing may help on some machines.
But its not all doom and gloom, a backlash against Gasohol is already happening , Chevron /Texaco were going to stop selling regular 95 and only sell gasohol 95 but my sources tell me they have cancelled the idea and will continue to sell regular 95 as will Shell. jet has stopped selling regular 95 but Jets sales have fallen as people desert the forcourts so they may reintroduce 95
Thai consumers have noticed up to 10% less mileage per litre on gasohol which makes it more expensive than regular also the debate about Biofuels staeling food from peoples tables is ongoing.
Farmers have found that many types of petrol driven farm machinery ,pumps ,generators ,threshers etc do not run on Gasohol .
Also water contamination from separation of water in gasohol is a problem and many consumers have had engine faliures and had to have fuel tanks drained . it also causes other problems as its storage life is not as long as regular fuels..
I have traveled widely around Chonburi ,Rayong and Trat this week on the Ducati and found Regulkar 95 more available than 3 months ago. The Ducati S4 does run on gasohol but I still try to get 95 as often as possible .
Jerry you have to realize that we need ethyl alcohol to boost our gasoline with octane, Before and probably still today they use a little MTBE or something alike to boost the octane. That is derived from methyl alcohol or better known as methanol which have much worse corrosive side effects than ethyl alcohol ( if you know somebody racing with methanol he can tell you. You can’t even leave the fuel in the engine overnight!!) ). MTBE boosts the octane and it is like etyl alcohol an oxygenate that adds oxygen to the burning process. MTBE also reduces the unburned hydrocarbons and carbon monoxide in the exhaust also like etyl alcohol. The problem with MTBE and it’s derivates is that it is cancer causing.
One point that could back up your “experience” is that the better octane booster you use in the petrol the lower class gasoline
(gasoline derived at a later stage when the crude oil is heated up) you can use. That could explain the problems Jerry have experienced . On the other hand I think that the ethyl alcohol is mixed into the petrol at a very late stage and I am quite sure that it is mixed in the gasoline used for normal 91-95. Maybe Jerry your friend at the Mathaput refineries can tell when they mix the different blends.
You told us that Gasohol tends to leak water into your tank and petrol system Where have you got that from? You said:
Also water contamination from separation of water in gasohol is a problem and many consumers have had engine faliures and had to have fuel tanks drained . it also causes other problems as its storage life is not as long as regular fuels..
One of the advantages with Gasohol is the blend’s ability to absorb water which may help to clean up the petrol system. Pure gasoline can not be mixed with water so the water is left all over the systems as small “rain drops”. Ethyl alcohol absorbs water, especially 99,5 pure alcohol. (everybody who has done “moonshine” alcohol knows how difficult it is to get the last water out when distilling the “moonshine”.)
An other advantage of the gasohol blend is that the ethanol’s corrosive power helps clean up the petrol system (fuel injection as well as carburetor system). Off course that can cause a problem when you change to Gasoline because all the rubbish is mixed with the gasoline and can be stacked in carburetor.
And Jerry you have a tendency to say “ consumers have that and that experience” Where do you take the information from since I can not find it…Pls don’t say that “ my neighbor….”
From where have you heard that gasohol “gets bad” more quickly than traditional gasoline. Pls remember that the only no gasoline item in Gasohol is pure 99.5% alcohol. Do you think that get “sour” when get old…..I think it is the other way around. Traditional gasoline have MTBE or it’s derivates which “gets old more quickly”.
I try to believe you Jerry when you say that you get 10% less mileage on Gasohol. But are you sure that you really checked it up or did it just feel like that. How many kilometers did you do to check it up. Same weather condition, same road conditions etc ?
The reason I ask you is because you have posted some posts before that are not so accurate:
When i run my non EFI Honda 125 wave on gasohol95 the fuel consumption is 25% worse so no savings for me , the bike is not as smooth either.
I put a few litres of gasohol 95 in the Ducati yesterday and the bike ran OK but there was more vibration and a bit less power and response the exhaust note was a bit flatter too.When i refilled with regular 95 the machine was better a little smoother and harder edge to the sound and a bit more power
Since the 10% blend is very lean it is quite questionable if you can detect the increase in power or mileage. The energy value in pure gasoline is 18.000 (BTU/LBS) and in ethyl alcohol 13,000 (BTU/LBS) and thus Gasohol has 17,500 (BTU/LBS) . That indicates a loss of mileage at approx 2,8 %. Then we also have to take into account that the stoichio-metric air-fuel ratio (which means the chemically optimal air/fuel ration) which is about 9 for ethanol and 14 for gasoline and thus 13,5 for Gasohol. This means that that ethanol can accommodate more fuel than gasoline, thus producing more power but worse mileage The ability to take use of the better air/fuel ratios is easier on fuel injected vehicles than carburetor models. Still we are talking about an 1-3% increase in power and about the same decrease in mileage.
Anyhow all talks about huge decrease in power and mileage are bullshit.
But we are lucky to have our own “Jerrymeter” on this board. He and only he can test and give accurate information about power, mileage and sound, taking into account altitude, temperature and different fuels only using his left side of the brains.
[i]I find it strange that many people do not notice subtle changes in how their bikes run due to fuel, altitude, temperature , I have been working on bikes for 35 years and can hear and feel differences in running on many machines that indicate faults or poor fuel etc.
May be it is because i started on primitive old Brit bikes and Hds .

The rubber deterioration is a more serious problem. Anyhow I don’t believe in any immediate problems when changing to gasohol except that the gasohol may clean up old rubbish in the fuel system. The ethanol blend is still quite lean and it will take time before problems can occur because of Gasohol. Also most of us have bikes newer than 10-15 years and they already have E10 resistant rubber parts .
Some older carburetor bikes may need fuel lines and rubber components in the carbs updated with Gasohol compatible parts.
I can believe that farmers have had problems with their machines. Have you ever seen a farmer who doesn’t complain. Anyhow I would like to know what is your source of information. How many farmers complain? How representative is that group etc. Or did you just thought that they must have problems…….
But its not all doom and gloom, a backlash against Gasohol is already happening
It may be true but I haven’t seen such an information in the newspapers, internet or on tv. I am very impressed that you have sources inside Chevron/Texaco, Shell and Jet giving you secret figures. The thing I had read is that Gasohol is moving faster than planned in Thailand and now they are introducing E85 gasoline earlier than planned. Gasohol has already 50% of the market. (my source Bangkok Post and Nation)
Thai consumers have noticed up to 10% less mileage per litre on gasohol which makes it more expensive than regular
Again this statement could be correct and if you make it in England, it can go like that, as everybody in England know ,or at least think you know, because you live in Thailand and know most of everything in Thailand. But now you are in Thailand so please give your source. I haven’t read about it any place. Is it only what you hear from Thai consumers then how many Thai consumers you know (the sample) and how many Thai consumers are there (the whole population) (I don’t remember anymore if this is the right mathematical vocabulary in English) Or maybe it is as usual that you think Thai consumers must have noticed 10% less mileage, because Jeff has…..
And then we have ongoing debate of Biofuels staeling food from peoples tables.I will try to make it short and simple despite that it is a complicated issue.
You need a Kubota to go to rice field many times. You need a Kubota to pump the water into the field. You need a Kubota to prepare the field (that is when you put the metal wheels on ) You need a Kubota when harvesting. You need a Kubota when you are bringing the rice sacks to the rice dealer. A very very high portion of the cost to produce rice is gasoline. It is so high that for example the extra gasoline cost for pumping water into the fields for a second season a year is higher than what you get for the rise. So under normal circumstances a price increase of gasoline must be reflected in the price of rice otherwise the fields would be idle. Nobody wants to produce rice when cost is higher than the selling price. If that happens and the selling/buying price is still lower than the cost to produce rice the Government steps in and buy the “extra” rice at a higher price and put the rice in government warehouses all over the country. Normally this happens when the rice harvest is good and plenty of rice is produced keeping the price down. These government bond warehouses are a continuous story of scams and frauds. Rice of a certain quality grade should be found but no….Rice of quality A was put in but quality C came out etc. The stocks in the warehouses can also be collateral for bank loans and hups!! what has happened to the collateral…..There is also a lot of politics in this rice stocking, before the elections the ruling party buys up rice at a high price to get the votes and leave the rice stock “bomb” to next government. Thai style but all over the world subsidies fuels corruption. If somebody living permanently in Isahn or somebody else with inside information pls correct if I tell lies. I would be happy to know more.
That is the easy side of this problem but why have rice increased at the most 3-fold and anyhow much more than the price of crude oil. Some people try to explain that with claims that the Ethyl alcohol business needs the crops. That is partly correct but agriculture business is quite slow to change. If you grow rice now on a small land you cannot convert alone to another crop and your land may not be suitable for another crop. In agriculture all changes are slow and all price changes should be slow.
This time however everything went fast and maybe to fast. The world realized once again that the globe must produce more food and we need more idle land to grow food. That is mainly Africa that has that. Anyhow this together with the rising cost of everything caused land price to increase making it even more expensive to produce food.
At this stage the most greedy Capitalists moved in buying future crops for delivery year++ at price xx and when the price situation changed they sold this paper again with a profit. And this business boomed causing prices to spiral up. Now lately the most greedy and well informed have left the market and the prices are coming down. It is a little questionable how moral these futures markets for food are and the futures markets have far outgrown their agricultural origins. Now it is plain business and most agricultural stables are bought and sold on these markets.
So the prices will start to come down again but everything will be more expensive than before because oil prices will not come down in the long run. But for Thailand this can be good. A high rice price will benefit the farmers since Thailand is the world’s biggest exporter of rice. A high rice price will enable the Thai government to sell out their huge rice stocks at a good profit. Higher prices for land will help the debt situation for farmers with high debts.The bad thing is that all Thai people have to pay more for their daily rice and that can be a tough thing to swallow.
Anyhow Gasohol is not
staeling anything.
I am happy that you have driven widely around the eastern seaboard last week. Sorry we didn’t see each other. Anyhow you need some km:s in your meter. When you tried to sell your Ducati about 6 months ago it had 12.000 km on it. When you bought it a little used in 2002? it had a few thousand already so you have done 10.000 km in 5 year that is about 2 Eastern Seaboards tour a year….Or maybe the meter had made a turn so it is 110.000 km…. I think that Captain Slash can have a laugh.
