Where do I find the right Gasoline for my Moped?

The reason for this could be that it was old. As it's more expensive than the 91 gasohol = few people bought it, and it got old. Hence it runs better with 91 gasohol which 99% of the population buys, and gets replenished more often.

IMO there's no way 95 benzine would make your bike perform worse than 91 gasohol.

Thanks for your post. As far as I remember did I switch to NGK Iridium after my bad experience with the 95 and yes, I understand, it makes sense that basically nobody's buying 95 and it must have been old.

 

  I've just changed my oil, hit the road and the bike's running great on 91. It's been like that since August/ September and I appreciate that my bike's running well on 91.

 

  Keep them wheels rollin'..........

It's a 1100cc Virago with two carbs and a TPS Throttle Position Sensor, only a few bikes were made with one) I wrote that it was bought from a shop ( Red Baron) in Bangkok 16 years ago, not that it ran in Bangkok. 

I had the Bulldog version of this bike in the Uk.

Frighteningly fast.

It's really fast and an edition of only 2,500 that were built.

The gear box is differently stuffed, so less RPM's when accelerating than other Viragos. 

 

   165 km/h was all I could do until now, it's just too dangerous to ride faster. Not on Isaan roads with all the crap driving around. Yamaha talks about 190 km/h top speed, but 180 km/h suits me well.

Don't think I ever got mine to 100mph in the UK.

It was my divorce death wish purchase, but the death wish wasn't that strong.

I'm not planning to buy new valves, seats etc and spend a lot of money on it. I've got only 19,600 km's on the clock.

 

  But thanks for your input. 

I have strong doubts that an 1996 engine was designed for run any Ethanol. You might find related info on the Yamaha website.

It took me a while to find such info for my 2001 bike, now I am sure i can use Gasohol.

From that point of view stay safe and run it with pure Benzin. Ethanol may damage your rubber/plastic sealings.

No engine minds higher octane, only too low octane for long time could create troubles.

 

Assuming you did all 19,600km in 14 years, it means you do max 1,400km a year, 120km a  month. Most probably less.

Furthermore assuming an average consumption of 6l/100km:

=> 84l/year => additional cost for use of 95 instead E95 approx 650THB per year , 55THB or 2l E10 a month !

So what?

 

In my humble opinion the mentioned not-well-running in the city comes more from partial use of gasohol and simply not running enough km to keep tank, carburator and seals clean from influence of Ethanol.

 

Ride safe mate!

Sounds to me you're looking for trouble 😄 if it runs well on E91 then it's carbs and timing have been tuned to it, E95 shouldn't be a problem either.

I will add that my bikes happily run on E95, the Guzzi will run on E91 at a push

I know you guys know this but for others:

 

There is no E91 and at least currently in Thailand no E95. The E prefix is used to specify the ethanol percentage in the fuel. So E91 theoretically would be 91% ethanol.

 

All gasohol - both 91 and 95 octane - in Thailand is E10 so 10% ethanol.

 

Benzine has 0% ethanol and in Thailand comes with 95 octane rating.

 

IMHO it's better to say "gasohol 91", "gasohol 95" or "benzine" for the common motocy fuels.

You either have a wicked sense of humour or a fascinating insight into history, certainly makes my "Benzine" boring 🙂

Of course the Benzene is also 95 octane.

But it would surprise me if your bike has a problem with higher octane. Usually it's the other way round.

Exactly, something is wrong with his bike. Going to lower octane will cause the problem of pinking, going higher octane is just wasting money but will not cause engine problems. There used to be a 91 Benzine, red pump but you do not see many these days. Maybe his bike needs Leaded gas? But that would make it a dinosaur.

I'd never thought about that. After some Googling, it seems that you're right:

 

  “Benzin”, the German word for gasoline/petrol is actually named after Karl Benz, the inventor of the first motor car, who built one it 1885 and patented it in 1886 as an "automobile fueled by Gas". “Benzin”, the fuel his car actually ran on is consequently named after him. Other Germanic languages and Polish also use similar names for it.

Regarding Yamaha, 87 octane is okay for this bike. 91 octane with 10 % ethanol seems to be okay. 

 

   Thanks for your post.

I thought whether I should bring this up and decided against :biggrin:

 

Gasoline, petrol, gas. Pick what you like best.

PTT uses gasoline on their website while the Thai script for this fuel corresponds to "benzene".

Even when it sounds weird, he's right. It was named after Mr. Karl Benz, daddy of Mercedes. Mercedes with her daddy Karl:
