Move to replace gasohol 91 with gasohol E20

The Department of Energy Business is planning to ask the new energy minister to push E20 gasohol as the country’s basic benzene fuel and stop sales of gasohol 91 altogether, said department director-general Nanthika Thangsupanich.

 

“Originally, we planned to announce E20 as the basic benzene fuel on October 1, but had to postpone this indefinitely because most of the ethanol – a key ingredient in E20 – was being used to manufacture hand sanitiser gels for the prevention of Covid-19. The department will now propose the plan to the new energy minister once he takes the place of minister Sonthirat Sonthijirawong, who recently resigned,” she said.

 

“We expect the move to be announced in nine months after it gets approved, as the cancellation of gasohol 91 will require some time for petrol stations and consumers to adapt,” Nanthika said.

 

“In the first three months, we will use a price mechanism to attract users to switch to E20, while the remaining six months will go for refineries to gradually slow production of gasohol 91.”

 

The department also instructed petrol stations nationwide to change the name tags of diesel fuel from October 1 to prevent confusion. B7 diesel will be called B7 biodiesel and B20 diesel will be termed B20 biodiesel.

 

Nanthika also said the department would present to the new minister a pilot study on trading palm oil via blockchain.

 

“Currently, we have three companies interested in joining the project – Energy Absolute, Pathum Oil and New Biodiesel, which will buy 120,000 litres of pure palm oil [B100] at Bt23.16 per litre,” she said.

 

“This will push the price of oil palm bunches to Bt3.2-Bt3.6 per kg, which is higher than the recommended price of Bt3.13 by Commerce Ministry,” she added.

Apart from the possibility of seal failures which are easy and cheap to replace what other damage could using E20 in a brushcutter / mower type engine do?

 

There's no way to adjust the timing and the mixture is fixed by the jet size too.

What about E85? Readily available thru out Issan, not seen it in the South. Even cheaper than E20.

That e85 krap isn't sold around here.  Up in Muang Phitsanulok a PTT was flogging it a while ago but I don't know if it still does.  Gasahol 91 or 95 is bad enough.  Several years ago I bought a backpack weedwacker and that Gasahol 91 buggered the fuel delivery line, I replaced it and before long I had to replace it again.  Then I put a silicon line on it and it wouldn't run right.  I'd get it running and use a tank of mix, stop to fill the tank and it just wouldn't start again till it was dead cold.  Had 2 small engine guys look at it but they were no help for whatever reason.  Took it out again and discovered the silicon fuel line was leaking.  I put it on the shelf in the shed and that's were it has stayed for the last 5 years.  I don't want fuel leaking and someone to get badly burned....it maybe me!  I see a lot of problems with these donkey fart fuels.

Luckily 95 either pure or 10% will remain available although more expensive. Mixing with E20 to reduce the alcohol concentration is a possibility.

 

I'm not going to risk E20 in my small engines, I've not managed to get a sensible reply from any of the seal suppliers as to whether their product is E20 compatible. The manufacturers stick with the "10% maximum" mantra.

 

 

I use a  mix of 95 and 2 stroke additive to my small 2 Stroke Engines ( Weed wacker Etc )

There are no issues with this in 2 Stroke Engines 

I also use 95 in my Old Quad Bike, again no issues.

However, I can forsee issue in the small Motorcycle Engine that uses 91

So how many small engines / motorcycles ARE actually E20 compatible?

 

None of the existing engines will have an issue using either 95 E10 or pure 95 apart from cost of course. 

 

EDIT Just to partially answer my own question, all the current Honda bikes are E20 compatible.

Wow, that is very deep thinking. How will Thais understand the word 'Biodiesel?

Here in the USA, you can walk into the Home Depot and buy a quart or a gallon of synthetic, ethanol free gasoline for your lawn implements.  It's a lot more expensive than buying normal gas at the pump, but the typical homeowner probably uses a gallon or two a year.  And it's well worth the few $$$ to avoid ethanol problems.

 

If I were back in Thailand and of the entrepreneurial type, I'd be looking at offering something similar, and selling it by the liter through all kinds of outlets.   You may also find that street racers would buy it up to make their scooters run better at the weekly street meets.

Can adjust mixture on Brush cutters and Mowers , Just serviced mine and Readjust the mixture and idle.

Google for Engine timings on different small Engines.

Can Do.

Setting Briggs Ignition Timing. Install a top dead center finder tool to the top of the cylinder along with a degree wheel and pointer. Rotate the motor one direction until it stops, read the number on the degree wheel. Rotate the other direction until it stops, read the number.

Does your cutter have the Honda GX-35? Ours has only pilot air and throttle stop adjustments. The timing is set by the position of the magneto, there's no adjustment other than flywheel clearance.

 

Re-jetting for the different fuel is potentially possible if replacement jets are availabe.

In the good old times when I had zero money but was still tuning and racing my old cars, I used to bore the jets bigger with simple drills used for making holes in PCBs. They are cheap and come in 0.05mm steps. I even made them smaller by soldering the brass and then making a new hole. Works fine if you take care and time. A heated lambda sensor from a car will tell you the A/F ratio is correct when placed in the exhaust, just connect a multimeter and check the voltage.

Standard main jet (for straight fuel or E10) of a GX35 brush-cutter engine is .37 or .38mm (and smaller for the high-altitude configurations).

 

I have no idea as yet what it would need to be opened up to for E20. Still doing research.
