Is 95 octane the highest avaialble in Thailand?

[Tuvoc]

All I ever see when I visit are 91 and 95 Gasohol, 95 benzine sometimes, E20 and E85

 

Standard (and lowest) in UK is 95, and then there are the 97, 98 or 99 Premium available depending on brand.

As far as I know 95 Gasohol is the highest octane, there is some gasoline ( petrol ) available in Thailand don't know at what rating.

Most vehicle here run on 91Gasohol  E20 and more recent E85.

There was reports that 91 gasohol was being removed at sometime.

There is no higher than that at regular pumps.

95 octane benzene (gasoline) is available at major stations only for close to 37 Baht/liter currently (August 2018).

But you find it nationwide just not at every minor pump.

 

I remember some reports (rumors) that in the Bangkok area there are sources for 98 octane benzene for the "Ferraristi".

95 does for most vehicles.

I would say most people who want/need that fuel could buy it by the drum.

Well you can bet your boots that those Ferraris and Lambo's are not running on "benzine gow ha".  I always hear that racing fuel is available  in BKK.  No idea where but Google it.  Racing fuel in Bangkok.  Or similar.

[Briggsy]

PTT Group list 6 gasoline-category fuels for sale none with an octane above 95.

Out in the sticks here about 34b a week or two ago.

I believe the yellow 95 is the highest performance gas available in Thailand.

Yes at PTT the signs are yellow with black print.

And it is benzene/gasoline 95 (no ethanol).

Just a snippet when no choice.

Ferrari recommend not using ethanol and to use 91 - 94 octane gasoline.

As a practical matter, most Ferrari drivers decide to live dangerously and just buy widely-available premium unleaded with 10% ethanol. 

I've been told it's not a big issue, if you drive the car regularly.

England has 91 and 95. Shell "Ultima" is considered one of the best. Anything higher will require additives. What fuel makes do you believe offer higher than 95.

[The Fat Controller]

Tesco Momentum is 99 RON and available at most Tesco petrol stations.

 

Sainsbury offer 97 RON.

 

BP and SHELL also have products higher than 95

 

91 RON has been discontinued, basic unleaded is 95

Forgive me if any of these details are incorrect.  Perhaps someone else can chime in:

Buy a small bottle of nail varnish remover for 10 baht (it's just acetone).  Acetone has an octane rating of 150 (the max on the scale).  To a full tank of gasoline or Diesel you probably only want somewhere in the region of 1ml (depending on tank size, quality of local fuel etc).  I tried this in a diesel truck here a few times.  I think (without measuring it accurately) it perhaps had a little more go, or a little better economy, but not enough to be sure from confirmation bias.  What I did notice for sure though was that it was much smoother and didn't hesitate from a standing start nearly as much.

I did (or at least I did in UK) think that 98 was 'high performance', whereas apparently that's not the case at all.  More like it softens the ignition into a smooth burn rather than an explosion with a better flame front.  Or summik like that.

Of course, do your own research first if you're thinking of doing this....

Although E20 is marketed at 95 ron, just by the nature of the increased level of gasohol it contains it is actually has a higher octane rating than 95 (98+) as per this link, be aware that your car must be capable of handling fuel with the increased levels of gasohol before changing to it however, older car's may need a new fuel pump, new fuel lines and other parts in the fuel system before they can safely run E20.

 

http://www.pttplc.com/en/Products-Services/Consumer/For-Vehicle/PTT-Blue-Innovation/Pages/PTT-Gasohol-Blue-E20-Test.aspx

 

E85 has an even higher octane rating of around 105 however for a car to be modified to run E85 if it was not orginally designed to the fuel system will need to be modified and the car will need to have its ECU remapped.

hope that helps

I just googled what kind of fuel Ferrari, Lamborghini, Bugatti, McLaren etc. use... it's 95 octane (some models just 91 octane)

So there is simply no requirement for higher octane fuels

In western countries you probably just find these "premium" fuels more often (they exist in Thailand, but are rare) because more people are willing to waste money on it than in Thailand.

Back in Europe this was 101 octane. Good stuff

[gaff]

Anybody has been using E20 since the first day when they bought a new car ? Is it better to change sometimes ?!

My wife uses only E20 for her HRV. Average mileage in city 1lt / ~11,5km. Once I put Shell V power in and the mileage was way better. But one liter cost almost 10 thb more than E20 at PTT, so back to E20.

If the car can use E20 use it, if the car can use E85 use it pretty simple really..

No surprise there and they could use gasohol fuels if they spend some dosh on changing engine components.

Interesting. I was not aware acetone was rated so highly in terms of octane.

An alternative hypothesis - acetone is mutually soluble with hydrocarbon or water. As water contamination in fuels is always an issue with fuels, perhaps the improved performance is due to a better azeotrope.

Are you sure the quantity is 1 mL ( millilitre )? I would have thought 1 litre in a fuel tank of ( for example ) 70 litres would be necessary to have any effect.

OK so Ferraris are fine on pump gas.  I think that may be recent, but whatever!  Thanks for the advice on that one.  Good to know in case I win major lottery and have a rush of blood to the head.  I would most likely probably buy a lexus SUV or a diesel SUV (Fortuner or Mu - X.  Bangkok has a huge collection of very expensive performance cars, many of which will need higher octane than 95.   I am sure it is available as a form of boutique product at specialist gas stations.  I use 95 zero ethanol (light green colour) even in my 4T Honda lawnmower and Honda line trimmers.  As it is the olly gas I have around the place it also ends up in any 2T  engines that end up here including contractor's chainsaws.

Cheers.

I have been using only PPT's E20 on my motorbikes since they where bought back in 2011 and 2012. Sticker on the motorbikes says use E10. The E20 is 98-99 octane. Running more than 30 000 km already and never had any problem.

36.9 in Pattaya this evening. They call it benzene and it's not easy to find. There is no indication of its octane rating on the pump.

No rush to the head if I win major lottery it would be a rush to buy my favourite Ferrari.

Well that's the thing no matter the octane value it's whether the engine components in the vehicle is compatible with using gasohol fuels.

Actually, now that you mention it, I think it was per litre, but with a full tank to know how many litres. 0.2% or 0.25% or something in that ball park.

If you google you will find a lot of reasons to debunk it.

You will also find a lot of people that got results.

In my own case it was mostly the response to the throttle being more immediate.  I didn't go to the trouble of mileage testing or getting it on a dyno as it was just a curiosity (and someone else truck Lol!).  I guess at that time it must have been a 2003-2004 Toyota.

Some claim that it was worth it for older engines, but just not required in newer engines since they burn cleaner, and the fuel these days already has additives to stop it coking up or other things we'd all forgotten about.

I am not an Auto engineer btw, so take all the above with a pinch of salt (just not in the tank!).
