Thread: Gas O Hall

What is gasohol ?

I don't understand the whole concept.


Why does it fok up your car ? How do you use it?

Can it be used in small motorcycles ?

What is it's purpose?

Gasohol is normal petrol with ethanol added.
Gasohol E10 contains 10% ethanol and E20 contains 20% ethanol

one of my Thai friends told me it was made from coconut husks.

Coconut is used in biodiesel. Dunno about gasohol though

You should only use it if your car is manufactured for gasohol use.
It can damage the fuel system. Fuel tank, fuel lines and injectors.

How to use it?
Just fill up and drive away

in what way?

normal 95 petrol that isn't gasohol is almost impossible to find nowadays.

what do you do if your bike/car isn't built for it?

Because alcohols are electronically conductive and may cause corrosive impurities, they are more corrosive than gasoline. Alcohol also attracts moisture, which increases its corrosive tendencies.

How quickly might such damage occur.

my bike has started to make some funny noises.

Just small sniggering type or a full out belly laugh type ?

hmm, nowadays petrol 95 in Europe usually contains 5% ethanol, and
most modern engines accept up to 10% without modifications so I don't think you have anything to worry about.

Regarding damage to the fuel system, check this link:

Ethanol vehicles - Is ethanol aggressive to material? - BSR FAQ

Gasohol can damage rubber fuel lines and some gaskets, expecially in older cars & motorcycles. It also produces less horsepower. Newer/Fuel Injected engines will generally not have problems as the FI will automatically compensate for the lower power, although you probably will get poorer fuel economy.

Older engines, especially older motorcycles, tend to have a lot of problems with this stuff! I'm going to sell my 1991 Kawasaki, as I've had to spend thousands of baht repairing the engine already, with no guarentee that I won't have more problems in the future!.

Petrol resistant rubber does not get damaged by ethanol.

I used gasahol when it first came out in the states in 1979 in a 1978 Dodge Big Block Powwer wagon and had no problems with it except got less milage, but it was also 10% cheaper than Regular gasoline.

And my wife ran hitest 95 gasahol in her 1998 Honda Civic and no problems.

Yea, coconut oil in bio diesel, but you aint going to get oil from husks.

Sugar cane is what they use to make ethanol here in Thailand.
It's pretty safe to use in most vehicles made in the past 10-15 years.
I avoid it because of the corrosive quality the fuel has. Ethanol absorbs water.
And I wouldn't want to leave it sitting for a long time in the tank.
Using ethanol will also get you worse fuel economy
As long as you have a choice you're better off using straight gasoline.

And that is the same thing that Mercruiser outboards and stern drives said in the early 90s about it's use in inboard and outboard engines, and the inboards were of Volvo, Chevrolet and Ford makes.

In engines made before the advent of unleaded gasoline, the engines were built of parts with alloys that were dependant on outside lubrication and was attained by Lead additives, after lead was removed the parts were made of different metals or you could add top lube by adding Marvel mystery oil to the fuel tank when putting in unleaded.

Have you remembered to put oil in it this time? Or is it that time of year where you like to rebuild your engines?

It fine to use in modern bikes. Provided you use the bike on a regular basis. Leave it standing for long periods. (weeks at a time) expect to start having problems with it.
91 is ok to use.

I've been using 95 gasohol in all my vehicles except a 28 year old Honda dream which doesn't get used much.
The 1995 BMW GS seems to like it just fine, the last 8000 miles and I've only notice a slight decease in fuel economy(less than 5%)
I wouldn't think a 91 Kawasaki would have any problems. That's a fairly modern and tough engine.

expect to see a thread about it in the near future...

I have ran it in all the bikes at one stage due to the pump sation not having anything else with out any problems. It probably gives them a good clean out
