Here is an article I wrote a year ago when the Ministry of Energy attempted to claim that all cars could run on E-10. Subsquently all major Thai manufacturers came out and stated that not all of their cars could run on gasohol.
If they won't run on E-10 you can safely bet that even less will run on E-20. If there is no petrol 95 we are simply screwed, and even more people are screwed worse with E-20
Oct7, 06:
Why does the PTT and the Energy Ministry continue to disseminate misinformation in an attempt to defend the ill thought through decision to withdraw petrol 95 and replace it with E-10 gasohol?
Bangkok Post reports Oct 6, 06 on a long-term test performed by the Dept. of Alternative Energy & Efficiency and PTT on 3 older Japanese vehicles claimed to represent 60% of the total number of 10+-year-old cars on Thai roads. Contrary to the test report, 2 of the 3 cars tested are deemed E-10 incompatible by the manufacturers.
The Toyota tested was a Corolla 1.3 litre 2E engine, (produced from 1985-90). Toyota's compatibility statement is very clear in that pre July 94 Corollas are not compatible, and "will not operate satisfactorily due to material incompatibility issues".
The Honda is only described as a more than 10-year-old 1.5 litre Civic with a CVC(C) engine. The only Civic listed by Honda as E-10 compatible is a 2004 or newer – clearly excluding the test vehicle. Honda then goes on to say that they do not recommend E-10 for some other vehicle models because there may be driveability issues.
The Mitsu tested is described only as a more than 10-year-old 4G-15 engine.
Mitsu's compatibility statement reads "all petrol engines manufactured since 1986 will operate satisfactorily ....... vehicles with carburetors before 1991 may experience hot fuel handling concerns and may experience a lower level of durability in some fuel system components".
Also tested were some unnamed 10 year + European cars, that the Ministry claim showed no engine problems. Euro manufacturer statements show however, that some or all models of Alfa, Audi, Fiat, Lotus, MG, Rover, Porsche, Ferrari, Maserati, Citroen, Peugeot, Renault, and Volkswagen are either gasohol incompatible or not recommended.
The Ministry is conspicuously silent regarding compatibility of the 23 million small motorcycles on Thai roads. Note that no major Japanese manufacturer, including Honda, Yamaha, Suzuki, or Kawasaki recommends the use of gasohol.
Thai vehicle manufacturers seem loath to publish a statement on gasohol. The public must educate themselves about compatibility, as the information coming out from the Energy Ministry and PTT is circumspect at best. See for yourself at:

The new government must review the decision, to stop selling petrol 95 Jan 1. 07, and rethink the Ministry’s stated long term goal to phase out petrol entirely by 2012. By all means introduce gasohol, but keep petrol available for those that have no other choice.
