It appears that the Thai government is once more propping up the palm oil business to the detriment of motorists.  Having got rid of petrol a while back, they're now getting rid of gasohol 91, forcing motorists to switch to E20.  Is there a list anywhere of which Thai cars can use E20 and which can't?

I believe all Toyota and Honda cars can use E20 from 2008 on...

Don't know why the wording has been translated as "forcing".

There is no word of abolishing gasohol 95 which is the obvious alternative.

Out-phasing 91 has been announced long ago (during last year at least).

91 octance abolished in Germany since > 10 years. An anachronism.

A car running on gasohol 91 will have zero problems with 95.
Price difference is marginal since long. 27 Satang as of today at PTT.

Some price reductions from today.

 

E20 might be risky if your car is not specified for.

(what car, how old?)

I have a Mazda 2, 2011 which is specified for E20.

99% running on E20 since then.

Could be true.

I only know from observation since 2011.

My car has a corresponding E20 sticker on the inside of the filler flap.

"E0 to E20 ... suitable"

 

BTW: PTT still sells petrol (without Ethanol) at major stations.

See picture above for 33.66 Baht.

 

I guess the OP refers to this article from The Nation:

"pushing", "promote" are the words.

Makes sense for those (majority?) who use gasohol 95 with cars specified for E20?

 

petrol/ gasoline no ethanol is available at a few brands of garages, as there is only 1/2 a bht between ethanol 91 and 95, i can not see any problem in swapping to 95 if e20 is not suitable for your vehicle.

my old car a 2006 honda city would not be suitable for e20

My knowledge of car mechanics is very limited, but I know that (perhaps 40 years ago) the timing of my motorbike needed to be changed switching from 91 to 95 (or whatever the grades were then in the UK).

Timing is usually altered if you use a lower octane to stop knock...But most engines now have knock sensors to do that stuff automatically...

And remember that E20 is knock strength 95 at least. I remember having seen higher numbers.

Petrol is 95 too.

Using E95 will be OK, you don't say what vehicle or the year your car is it may well be able to run E20.

Ethanol don't come from Palm Oils, 

Palm oils is for Biodiesel

 

Ethanol used in Thai 'Gasohol' of various strength is from cane sugar

 

E20 should have octane rating of around 98

E85 is probably around or over 100

 

If they stopped E10 'Gasohol'91 that'll means there's less option for older cars, but seeing the difference in price between 91 and 95 Gasohol, the jump to use E10 Gasohol 95 should be neglegible
