E10 is sold as "Gasohol 95" which should answer your question.

10% ethanol, 95 octane.

Where do you see "E10" on the signs?

I am not aware that any popular scooter or motorbike produced in Thailand would not run on Gasohol 95. Can't tell whether your model is happy with Gasohol 91 (91 octane, 10% ethanol).

E20 is not specified/recommended for most motorbikes.

What does the sign at the filler cap say?

 

Pure petrol (benzene) without ethanol is quite rare nowadays only at major filling stations.

Some historic/vintage models seem to depend on.

 

That's all what PTT offers (depending on station).
Pure petrol (named "benzene" here) is the yellow one (46.44).

Rare as written.

Gasohol 95 is the mainstream car fuel. Some use 91 for scooters.

E20 is fine for most motorbikes, and use it for our scooter, and  my cbx500. Crf runs on E10 same as my 1000

Thanks for that.

Just bought a new Toyota car and they strongly advised against E20.

Suprised me as I have driven about 140 tkm on E20 with old Mazda 2.

Old Honda scooter allows only E10 according to the filler cap sign.

Gasohol 91 is also E10, but they are phased out

 

on simpler ecu bikes that don't have O2 sensor while it's fine to use E20 and even say so in the manual and on the tank/gas cap I find that switching between them produce strange result, from running very rich to the point of stalling when switching from regular E10 to E20 and vice versa

 

 

95 and 91 is fine for my Honda Click 160, check your manual may say on the front

And the significant price difference that existed for some time recently seems gone/shortlived (now 38.15 vs 38.55). Subsidies cut?
