Gasahol vs Gasoline : Pumping for fuel in Thailand

In January 2007, Thailand has replace Regular 95 gasoline with 95 gasohol. Regular 91 gasoline are still allowed to survived but will be replace in stages until year 2012. So what is gasohol? And does it differ with our fuel?

Gasohol is actual a mixture of gasoline and alcohol, mostly ethanol. For the time being, Thailand gasohol is a mixture of 90% gasoline and 10% ethanol, coded E10. The mixture proportion is to be increase in later time. When? I don't have any idea. Can't read Thailand that good. Can't read Thailand at all!

Gasohol has been proven to have some disadvantages against gasoline. I experience 2 weird thing on my ZX10R while riding to Phuket early this month. Mr. Gibsi told me he felt his bike, which is the Kawasaki Z750s, underpowered after clocking 300km from Danok. I didn't really felt the effect since our riding pace are between 120-140km/h.


The first thing to be notice on the fuel is the color, looks like a Shell V-Power from the naked eye. It's set your mind that this fuel is already different.

The second thing is when we fuel up in Trang, I exposed my bike to a direct sunlight, with the temperature I guess that day felt like 32°C-33°C (or maybe higher). I've always fill up to the fuel reaches to the tank's lip. After just a few minutes, the fuel came out from the overflow pipe. This experience showed me the fuel is easily evaporated. An alcohol nature. From there I kept watch on where I parked my bike and always looking for a shaded area.

The third thing is while we on our way back to Danok from Phuket, we're on the highway 44 which is a long stretches of 100km going to Surat Thani. All five of us has a blast on our bike and my bike topped 300km/h with some effort to do so. On the 6th gear, when doing 260km/h, it felt like forever climbing to 300km/h. My bike are on a standard setup, and it never felt like this. So it is noticeable that the bike has loss some power. I do blame on the fuel. This prove to be right when we are back in Malaysia, after fueling at Petronas Bukit Kayu Hitam, then fill up again at Bukit Merah, the power come straight back again.

When we fill up at Pang Nga Shell Station on our way back, as always, I was just looking at the octane numbers. Kawasaki recommended a gasoline 95+ Octane and above for the ZX10R. So a pump with label 95 should do fine. Here, the pump attendant lift up the pump and said "Gasohol?". I'm a bit puzzle myself, if not, why do the pump attendant prompt me it's gasohol. Isn't it just a fuel? We didn't have any gasohol here, so what the heck gasohol actually is I really don't know. After safely arrived back only I did some digging on gasohol.

Digging on the web, there are no superbikes design to cope with gasohol. Manufactured vehicle for Thailand are actually design and approved to used gasohol since 1995. But bikes which are imported from Japan and Europe doesn't fit in the list.

So when riding in Thailand, it your not going for a long way journey, I think it should be safe to pump gasohol - for a short period. But if you planning a ride more than 10 fills up. Do try to look for gasoline.

Basic guide on the Thailand pump station is :
REGULAR 95 is labeled in Yellow
REGULAR 91 labeled in Red
GASOHOL 95 label is Orange
GASOHOL 91 label in Green

Although this might not correct for all pumps, it is mostly true for most of them. Do try to fuel in Shell, Caltex or PTT which is mainly a reputable gas station. My tips is, if you're bike can accept Ron 90+ and above, go for the Regular 91. Check the sticker label on your bike's tank, or check your bike's manual. But I guess, I can't confirmed because I didn't really notice, the price for Regular 91 is much more expensive than gasohol 95. Wait... Yup it's true. I've just browse the Net. Reg 91 somewhere 29.54 Baht (RM 2.99) and E10 Gasohol 95 is 25.74 Baht (RM 2.61). Notice Regular 95 is 36.64 Baht (RM 3.72) and only available from Petronas, Caltex, Susco and PT.

Update daily source here.
While gasohol advantage is that it might produce less emission, studied about 2% less than gasoline, it is reported to give less power than gasoline and lower mileage. Gasohol is also not friendly to older fuel injection and carburetors, even a new fuel injection which is claim to resist gasohol, it is not design for it. This case are meant on a superbike. Carburetors are claim can be damage with use of gasohol either in short or long term use and not very friendly to the plastic parts of the carburetors.

In other countries, there are arguement of using gasohol. But the noticable argument is about the cost of gasohol compared to the gasoline and is the consumer likely to gain advantage in using gasohol which in some country priced gasohol at gasoline price tag.

2009 BMW S1000RR Rumored Pricing



Word on the web is, the BMW will price the all new S1000RR bike which is schedule to debut at the World Superbike race on May 29th at Miller Motorsports Park within price range of the big four Japs, with expectation of just 10% higher. It will not compete along with Ducati 1198 or KTM RC8.

"We intend to take the four Japanese head-on. We did not intend to build a motorcycle like Ducati does or KTM does. We wanted to build a mainstream motorcycle," says Pieter de Waal, Vice President of BMW Motorrad USA.



For the sake of the fun of it, let's imagine. AutoBavaria Malaysia enjoys the same advantage Kawasaki Malaysia have, having the rights and APs to bring the bike here. So if the pricing structure is as attractive as the web claims, you can guess that the S1000RR should be around somewhere of RM 94.6K on the road. If this is true, R1, CBR and the Gixxer would have a real problem. But still, this is just rumored.

Kawasaki Ninja 250R vs Honda VTR250



Honda has recently come out with a new VTR250 for the European market. The 250cc segment is already being headed by our Kawasaki Ninja 250R.
So, does the Honda VTR250 has the dope to out run the Ninja 250R?

MCN has carried a comparison test of both the bikes. This is what they have to say:


"Although the new Honda responds better low down, from the mid-range up the DOHJC, parallel twin motor of the Kawasaki revs quickly and smoothly and its power increases more and more and its suspension has enough stroke to enjoy sport riding.”

Hint on upcoming 2010 Kawasaki ZX10R

Kawasaki recently filed patents for an in line four cylinder motorcycle engine with an uneven firing order. While similar to the design from Yamaha in the latest R1, the Kawasaki engine design steps things up a bit by adding some electronics to aid the uneven firing order.

The Kawasaki design would traditionally have had problems, in that the radical nature of the firing order would have made the engine incapable of running at low RPM, due to a lack of momentum in the crank on the long 540° revolution. The second problem would have been the requirement for a very heavy and almost impractical crankshaft, which would have made the engine slow to rev, and would have limited high end RPM.

Kawasaki have solved these problems by using clever electronics. An electric motor operates only on every second revolution, during the compression stroke, and only on cylinders one and four. This tiny electric motor operates only long enough for the motor to gain momentum, and then switches off again. Engine sensors are used to monitor crank angle, degree of throttle opening, vehicle speed and gear position. The new electric motor will also be used as a generator to charge the battery when it's not boosting the crank, and that means it can do the job of the traditional alternator too.

What does this all mean? Well to you and me, probably nothing other than a bike that sounds like the Yamaha M1, but if you are a really good rider, you will now be getting more traction and therefore better feedback from the rear tyre under acceleration, meaning faster corner exits, and ultimately better drive out of corners which means better speed down straits and hopefully an advantage for the green team (and don't they need one right now?)

The radical 540° gap in the firing order is double the gap that the new R1 uses, and means that the ZX-10R motor turns a full one and a half revolutions without any cylinders firing. The gap in the R1 firing order is only 270° which in itself was considered rather long.

However the most significant benefits from the Kawasaki design are that the crankshaft retains the natural balance as found in a traditional (screamer) in line four. This in effect reduces production costs, improves reliability, and also enables the normal high rev limit found in screamer engines, which means that the peak power output will not be adversely affected.

It seems like next year the major brands will all be making V4's or 'Big Bangs' if they want to stay competitive. Aprilia have already gone the V4 route, so we still need to find out what Suzuki & Honda have planned. Honda could easily build a V4, and Suzuki have the GSVR in MOTOGP which is a V4, so they know how to do it too. It looks like 2010 is going to be another one of those years with amazing technology coming to the consumers because of racing...
