91 Ron 95 Ron Or 95 Gasohol E10

[sunnyhor]

Hi all people in TV. Kindly solve.

Forgive me for digging up old forums but after researches in here, I still got no clue!!! Sorry and hope that someone might have constructive inputs.

I will be driving my vehicle into Thailand, but the manual of my vehicle stated, minimum 91 octane ( RON ). All the while I am filling with at least 95 ( RON ) and in my country, we do not have anything called Gasohol.

Now the questions,

1.) All the while i am using minimum of 95 ( RON ), can I fill in 91 ( RON ) if I could not find a similar?

2.) Will filling 91 ( RON ) affect the performance , the engine or the tank?

3.) Can I replace it with 95 Gasohol E10 instead, but my manufacturer commented, NOT ALLOWED TO!!

4.) Heard that whole of Thailand does not sell RON 95 anymore, it's illegal? So Benzene or Gasoline (pure) no more exist in Thailand?

5.) If I were to pump in 91 octane ( RON ), how much booster must I fill in for a 80L tank, will this do the job ( boost up a little )

Sorry for these noob questuons, but I really appreciate help! Thank you very much for reading!

1. If your car is speced for 91, there are no advantages (or extra power etc.) using 95. You have previously just been wasting your money buying the higher RON fuel.

2. See above.

3. If the manufacturer has commented (in writing) "not allowed to" - they may not honour warranty obligations, however, almost all cars built in the last 8 (?? - I am sure someone will correct me ) years with ECU will run on E10 just fine. Some may have issues with rubber components in the fuel delivery system.

4. ULP95 is available, however, only at at very few filling stations and the price is over 50B per liter. The government is taxing it out of existence. ULR91 (Benzene, gasoline, or petrol depending where you come from) is widely available and contains no ethanol. It is about 7.4 Baht per liter more expensive than 91E10.

5. Booster??

yepp, If your car is recommended to run 91 petrol, do so, in your homecountry and here in Thailand. No gain in increasing octane, no harm either but wasted money. Some cars can adapt to different RON, higher RON higher power, but then they sure mention it

avoid gasohol, E10 or E20 if your car manufactorer says so. Even tho cars for Thai market have been gasohol compatible for a few years, it does not mean they use the same parts for your car

Ethanol compatible cars have neen available in Brazil for 4 decades, but Brazil and a few other markets only. Blending ethanol into petrol is rather new for the rest of the world, including Thailand

Thanks for replying, yes my car spec takes ONLY 95 RON, the RON 91 is the last option meaning the minimum my tank can fill. Booster means Octane booster, an addictive to boost up more RON.

[sunnyhor]

Exactly, but my country do not have anything below 95. So 95 is the cheapest and lowest grade. My car manual stated, the MINIMUM I can go for is RON 91. So can I pump with RON 91 and add in some addictive?

Anyone can tell me what station do sell 95 Gasoline? What Petrol brand?

It seems to me you are not reading what has been said.

You say " the manual of my vehicle stated, minimum 91 octane ". SO USE 91 in Thailand indicated in RED at the fuel stations.

You do not need to add any additives.

Don't use any Gasohol fuels.

[sunnyhor]

Thanks bro Kwasaki. I had read all the replies. I am paranoid, because I had not use ANY of the 91 RON from the day 1 I own my vehicle. So all the while I am filling with RON 95 Gasoline.

I know my manual stated, MINIMUM 91 RON but I was wondering, will this 91 RON gasoline affect the vehicle? Like the performance wise and the fuel tank, any minus point?

Let us know what kind of car you have, make, model, year, engine, cc/hp, sold new in which market, and we can probably see if 95 is of any advantage to your car

But with info provided so far, I am sure you can run 91 petrol, colored red in Thailand, and no need to boost octane/RON

[sunnyhor]

Thanks bro. My ride a Nissan Murano 2.5 SL, 2005. Why I only use Octane 95 because my hometown do not have anything lower than this.

Euro spec Nissan and Honda have passed few years required 95 and thus output is 10% higher than 91 spec engines.

If your car is Asia or US spec, it requires 91 only, and as 91 is recomended/accepted in your manual, stick to 91 in Thailand and save the money. Octane booster is also a waste of money.

I would not take a chance on Gasoho/Ethanol 10%, as it is not a Thai made car, but if it is occasionally only fuel available, I would fill up 20 liter until petrol is found again

[sunnyhor]

Thanks for the advice bro. I would not take the risk filling with Gasohol too. I would rather fill the 91 PURE Benzene...... But my question is....I had not pump in petrol lower than the 95 octane, if this time I'm gonna fill with 91 Octane, will it "hurt" my engine? Alternatively, the performance will be sluggish? Sorry for this noob question because I'm no savvy knowledge on cars!!! My car manual recommended the MINIMUM grade to use is, 91 Octane RON

91 petrol will not hurt your engine or fuel system in any way, and performance will be the same as using 95 petrol.

I believe Shell does not sell petrol any more, only E10 blends even tho they are called V-Power, so stick with Ptt in Thailand and look for the red 91 pumps

have a nice trip

[sunnyhor]

Thank you bro katabeachbum........ the entire Thailand ONLY Shell don't sell pure Benzene from my research! So I think any other Pump that sell 91 Benzene will be suitable. I think I will try to stick to Caltex.

Any bros ever add in addictive like Octane booster for 91 RON ? If so, does it really boost up the RON?

I think only certain engines will respond via the ecu to higher RON. I seem to recall that the honda 3.0 V6 engine does this. Also the V6 engines in Australian holdens and fords too. I stand corrected if I'm wrong. It's best to ask the manufacturer about this. In my civic, on both gashohol 95 and 91 it made no difference. Actually I think fuel economy was worse on gas 95 the time it was accidentally added. Even 91 vs 91 gasohol I found little significant difference in either performance or fuel economy (more effect on economy though).

[sunnyhor]

Unfortunately it's not my case. I'm driving a foreign vehicle to Thailand, and my manufacturer said..... GASOHOL NOT ALLOWED in my car and she said, in Japan, she don't know what is Gasohol. So I better follow what the manufacturer said, no choice but to fill in lower Octane fuel.

But I thought those Octane Booster selling in petrol kiosk can boost up some......hmmmmmm, too bad I have to use lower grade petrol in Thailand.

A useful link which gives you an idea of who sells what..

Thanks bro kotsak . I had seen this website, and at least I know ONLY Shell in Thailand don't sell pure Gasoline. Even their V Power is a 6% of ethanol mixture, and I'd take note and avoid Shell at all cost.

The OP seems to want to waste his money buying higher octane gas. In the US many high end cars are rated for high octane. I've seen it stated many times, a lower octane will not hurt/harm the engine. If the performance is different or your getting pinging than use the higher octane. I once bought a new Acura that I knew used high octane. As I was waiting to pick up the new car I watched the salesman drive over to the gas station next door and fill it with regular. After a couple of tanks of high octane and not seeing any difference I went back to regular permanently. No difference in performance or gas mileage.

The computers in the cars sense the difference and make adjustments?

if an engine is designed for 98, but it runs 91, some car have a knock sensor detuning engine to accept 91. Of course gas milage gets worse, and powerloss from 98 to 91RON is approx 16%. Saab used this tech on all turbo engines since late 70s, and has later been pioneers on E85 making their engines able to run any fuel containing some petrol any grade

2011 Accord 2,4 is in TH and US sold as 91 compatibel providing 180hp. In Europe its 95 compatibel and 200 hp.

More and more euro designs are now 98 to improve power and milage and reduce emission. They have no problem running lower RON, but it affects performance, milage and emission

[sunnyhor]

Who will wanna waste this type of money? Did you see my earlier posts? In my country, the lowest I can find is 95, that is why I am filling with 95 but not 91.
