Correct. 91 octane has faster combustion and can damage an engine designed to run on 95 octane. You hear this klak klak klak klak when accelerating; not very healthy for your motor. It's useless to put 95 oct in a 91 running engine, just more expensive. Link to comment Share on other sites More sharing options...
transam Posted April 16, 2019 Share Posted April 16, 2019 I believe all petrol here now has a small % of Ethanol in it, think 10%.. Link to comment Share on other sites More sharing options...

No reason not to use the least expensive recommended fuel (91). I read that alcohol in the fuel pulls moisture out of the air so you should not store vehicles with fuel containing alcohol. (benzine 95 alcohol-free) IIRC Thailand Benzine 95 = 5% alchohol Link to comment Share on other sites More sharing options...
Jaxxper Posted April 16, 2019 Share Posted April 16, 2019 I'm told that using the "E" fuels does detract from the performance. My Honda will take anything from 91 to E85 but I always stick with 91. I guess the "E" fuels are OK in an emergency. Link to comment Share on other sites More sharing options...

eisfeld Posted April 16, 2019 Share Posted April 16, 2019 The very simple rule as to what fuel to use is to just use the fuel recommended by your manufacturer which is usually written somewhere on a sticker or worst case in the owner manual. Never go for lower octane than specified as that can damage the engine due to premature detonation. Using higher octane wont do anything (no damage, no performance gain, no increased/lowered consumption) and just cost a little bit more*. Apart from octane you also need to know how much ethanol your engine can deal with. Pretty much all vehicles built in the last couple years will be fine with the 10% found in Gasohol. Many can t ake E20 too, but just check as mentioned. Higher Ethanol fuels are cheaper but also consume more liters per kilometer so it offsets itself. When parking the vehicle for a long period of time, filling up with Benzine can be a good ideal as it is void of alcohol which absorbs moisture from the air. Fuels: Benzine (usually 95): 0% Ethanol Gasohol 91 and 95: 10% Ethanol (and 90% Gasoline/Benzine) E15: 15% Ethanol E20: 20% Ethanol E80: 80% Ethanol etc. And of course there's Diesel. If you put Diesel in a vehicle not made for it or vice versa, then you are headed for destination farked. *: exception are not-so-common higher performance engines Link to comment Share on other sites More sharing options...
johng Posted April 16, 2019 Share Posted April 16, 2019 If you put diesel in a petrol engine not much will happen as it won't run very well if at all...but no lasting damage.If you put petrol in a diesel engine...it will run and destroy the engine.

lvr181 Posted April 16, 2019 Share Posted April 16, 2019 What ever the manufacturer recommends. Don't go to a lower octane rating, unless you really need to and don't waste money on higher octanes because your car's ignition system is not designed to obtain the best performance available from the higher octane fuel (all modifications aside).

There is both 95 Octane Gasohol with 10% ethanol and 95 Octane Benzine with 0% ethanol available in Thailand. One could call the Gasohol also E10 though that name is not really used here. So what you were being told is not correct, there is no E5 here. transam: you should know better, old petrol head! ???? Link to comment Share on other sites More sharing options...

No idea what your "Solah" is supposed to mean, i think you got something wrong (or maybe it's Laos, Khmer or Lanna and not Thai) Thais say/write ดีเซล, which is just Diesel written with Thai alphabet. Because of how Thai works they read it "Diesen" (they pronounce it about like "decent" without the t). When standing at the gas pump and you say anything like Diesel, the Thai person should understand it. Link to comment Share on other sites More sharing options...

As the price diff was small I tried 95 gasohol. It seemed to have a bit more power But given the NYT article and answers here I wonder if it was the placebo effect. I started looking up specs online......no manual handy......but given the variety of names this model can have and also reading octane ratings can be different in different countries and people speaking of 87 on Suzuki forums I thought I’d present the article locally for comment. Kinda interested why there’s such a saving in the US but just a baht here.......do they use gasohol? BTW yesterday checked car no octane rating on door rim but discovered that someone’s put a Nissan fuel cap on my Suzuki Vitara with nothing written. If we think there’s no difference in power I’ll change back and buy myself a treat now and again. Sent from my iPad using Thailand Forum - Thaivisa mobile app That should be able to run on paraffin ... just add a little drop of the local whisky to help it along ...
