Gas Petrol Fuel - Options

[wjmark]

I have been using Caltex 95 in my new CBR150 - but they don't have it any more.

What should I use when all the stations stop carrying 95?

[helloall]

read your owners manual - I am sure you can run on 91 either gasohol or normal.

[JimsKnight]

For bikes with injectors gasohol is cool but CBR 150s don't use injectors.

Steer clear of gasohol if possible as it can rot the fuel lines/carb parts.

First time I went to fuel up my (almost) new Harley in April, my buddy told me to use 91. Apparently the 95 will cause the engine to knock and run rougher (my bike has electronic fuel injection). I thought using the higher grade, more expensive fuel would be better but apparently not.

For what it's worth, I asked the local Honda dealership if you can use Gasahol in the CBR 150R. He replied Mai Dee, and showed the front of the manual that said just 91+. Then he showed me a Click Play (?) which 91+ and Gasahol 91+ on it. I've ran Gasahol 95 in my CBR 150R and was quite disappointed with the performance. Even running regular 91 seemed to net me more power.

The local co-op used to sell 95, I think they've stopped. Quite disappointing.

Thanks - I don't see how 95 can cause knocking - I thought it was the other way round..

Anyways, my CBR150 seems to like the 95, and I will keep looking around to find it.

I think ESSO and Petronass still have 95.

And as my CBR gets 40km/liter (Honda km, that is!), I don't mind springing for 95.

Shall we form a '95 spotted at...' club/thread?

Cheers, Mark

Did I not read somewhere that they planning to stop 95? Nevermind, you can always mix at home in a well ventilated room.

Hey Richard!

Is that clever or just strange?!!!

Should I be mixing 95 gasahol with 91 benziine?

Or should I be adding a little av-gas to the mix? Kerosene? Lighter fluid?

Or do you mean I should be dropping a few moth-balls into the gas tank!

Cheers, Mark

@wjmark

It is just strange. But I really wonder what happens if the government is really pushing to stop selling 95.

HI

Not to many places in Phuket have 95, i would never run gasohol in any of my bikes

[PeaceBlondie]

I ran 95 benzene for a while in my CBR150R, and the only difference I found was in my pocketbook Switched back to 91 benzene, per the sticker on my owner's manual. Never tried gasohol and believe it would ruin the seals or rubber lines. No need to use 95 benzene when it is so hard to find. I get 32 km per liter, and often see 10,000 rpm and 125 kph on the gauges.

I have the same problem with my little KSR110. Always used 95 as advised by the dealer when I bought it but I can't get it on Phuket any more and I've only got about another 50kms left in the tank now...

I went to the dealer and he said just switch to 91 and it will be fine, but do I need to run the bike dry and then clean the tank etc before I put 91 in it, or can I just make the switch with a little bit of 95 left in the tank?

[LivinLOS]

I like to run 95 in my car and its getting tough to find.. Patongs clip joint of a garage claims they will keep 95 but as they run so many other scams there I dont know..

I am sure you can blend different octanes of benzene. Folks been doing it for decades without flushing the tank.

I was just going to start a new thread about this and saw this one. My new Nouvo came with very little fuel in it so I filled it up before I read the manual.

I filled it with 95 Gasohol.

Now that I've read the manual, I realise I should've used 91 Benzene.

I went to the Yamaha dealer today and asked about it, and they said I should run it dry (use up all the 95 Gasohol) before filling it up with 91 Benzene.

I don't believe this but the g/f is adamant that I do it.

I can understand why diesel in a petrol engine (and vice versa - which I did once ) will cause problems, but why on earth should mixing Gasohol and Benzene? Doesn't make sense to me. I would have thought regularly topping up with Benzene 91 would be the best idea - i.e. changing the mixture slowly from 100% Gasohol to 100% Benzene.

Anyone have any ideas on this?

JetsetBKK, I would disagree with the dealer mechanic. If ethanol is bad, it should be drained out, or diluted. I would siphon out what you can do easily, and just dilute it. It is only about E10 (10 percent) in the first place, right? If it is harming the engine, diluting it would cause less damage. I would not bother to flush it, though. I am no mechanic, but I think sometimes even dealer "mechanics" are not chemists.

This is what I was thinking . The "dealer" at my Yamaha shop said to run it dry, but JonnyF's said just "switch" to 91 benzene. My "dealer" was a middle aged lady who probably knew less about benzene/gasohol than I've just found out by Googling.

Since Gasohol is 90% benzene and 10% ethanol (please correct me if I am wrong ), and the bike will run on either, I cannot see why changing from gasohol to benzene 91 should require draining or running dry.

It's not as if the engine magically detects that 10% ethanol and switches to a different mixture/compression/timing or anything else.

HI

Just top up with 91, no problem. Gasohol can ruin the rubber seals. never seen it but heard of it

I think I'll be doing that unless someone gives a good reason not to.

Regarding corrosion, I found a link to a "specialist" that says ethanol is NOT corrosive: http://delphi.com/news/pressReleases/press...2007_02_16_001/

But the reason given is that although ethanol is not corrosive, it attracts water, and water can dissolve other stuff ("corrosive salts"), and it is the dissolved salts that do the damage. So provided you have good quality suppliers and storage facilities like we do in Thailand there shouldn't be a problem.
