My car on E20, 8 years, 120tkm. Since about 10 years most cars are specified for E20, some for E85 ("flexfuel"). Cars/vehicles are built for the fuels specified by the manufacturers and will work! But I am tired to repeat. Model T might have a problem. Link to comment Share on other sites More sharing options...

They tried some years back to stop selling "Benzine" the HiSo boys in Bangkok with their high end cars were not amused - so doubt it very much!

My cars and bikes here sit for 6 months - tank full of 95 Gasahol The key word there is "Full" leave them half full (or empty!) and you will have problems, learnt that the hard way!

How would that affect crankcase seals? As part of the induction process in a two stroke motor the fuel mixture is drawn from the carburettor into the crankcase (by virtue of the rising piston?) and then is pumped from there through the transfer ports into the cylinder above the piston ready for the compression stroke. So the fuel/oil mixture is in constant contact with the crankcase. My first bike, way back in the 60s, was a two stroke with worn seals and the primary chaincase used to fill with oil over time and mess with the clutch!

Alcohol is supposed to wreak havoc with the crankcase seals. The nearest places where I can buy a can full are now some 60ks away in the larger cities. Let's hope that it doesn't vanish completely. I have a 2 stroke Yamaha outboard and also faced that dilemma several years ago when benzene got harder to get hold of around Bangkok. I read lot's of conflicting advice from around the world about gasohol in 2 stroke outboards. In the end I decided to avoid the hassle and just go with gasohol. So several years (would guess about 5) later and there have been no issues whatsoever. Edited February 15, 2020 by thedemon 1 Link to comment Share on other sites More sharing options...
jadee Posted February 16, 2020 Share Posted February 16, 2020 The Thai gov is planning to make E20 the 'designated' fuel soon, but I don't know about whether they'll stop benzine. Link to comment Share on other sites More sharing options...
KhunBENQ Posted February 25, 2020 Share Posted February 25, 2020 Bad news (update). From years of observation I stated that "major" PTT stations still have benzene (petrol). A mate told me that he got it last week in our area. Today I did a 200km return trip to Khon Kaen (for an unrelated reason with newer E20 car). And all the major stations do not have it anymore. Only one PTT station where I usually pass by had it (I drove in to doublecheck). So prepare for problems finding benzene depending on your area. Anyone interested in a 15 year old Vios, 85 tkm, first hand Link to comment Share on other sites More sharing options...
canthai55 Posted February 25, 2020 Share Posted February 25, 2020 Unless you are driving an Ark, gasahol will not harm any vehicle built in the last 40 years. All those doom and gloom - ers are living in the 70's when it first appeared, along with the problems. Long since fixed 2 Link to comment Share on other sites More sharing options...
