Water in petrol causing missing.

[rally]

 

Hi gang,

My ST 1300 has done 150000 klms without a glitch, last month it started to missfire and would not idle....Friendly motorcycle mechanic at Helensburgh diagnosed a crook batch of petrol where I had picked up some water...Remedy a good fuel additive allowed the water to pass through the injectors, have done another 3000 klms with no further problems.

A good dose of metho helps there, it absorbs the water and allows it to mix with the fuel and get burnt, ( in a way that is) sort of give as water meth injection.

Got a mate do it to his car in Malaysia after he caught his very young son helping him by filling the tank in the car with the hose. He needed a few gallons of metho but.

Do you put the metho in with the fuel or do you put it in an empty-ish tank?

[Biggles]

Add it at any stage.  It "finds" the water and mixes with it making it "flammable".

There is a formula for the correct amount of metho to completely mix with the water, but as the quantity of water is unknown then the amount of metho is unknown. The best method in this case, is a coup[le or three gluggs plus a couple more for good luck.

How much is too much metho to add causing the internal combustion to become external combustion?

E10 Petrol is going to contain around 2.7 litres of ethanol per ST tankful, so I'm guessing that a couple of generous Gluggs in a full tank won't be doing any harm.

Can anyone point me to a measuring jug calibrated in Gluggs?
Google let me down on this one.

An amount equal what you used if you drank the stuff as some drunks/homeless people used to do in desperate times.

A glugg is a self calibrated unit, that is determined by the diameter of the container and the barometric pressure at the time of pouring...

A Glugg is bigger than a Slop and a just a bit smaller than a Gurgle.    It near the mid point on a coke bottle where you don't need to drink any more, but will anyway, or the level on a jam tin where you need a spoon for the jam, 'cause it slides off the knife.

This post is not only technically void but also helpful.... Outstanding work.

Hi all, I regularly add a cup of metho to the tank of my Discovery (Diesel). Helps clear any water in both of the filters. With different vehicles, mostly 4x4,  both petrol and diesel, theory is, it absorbs the water, therefore takes care of any rust forming in the tank and in the lines. Its too easy to get bad fuel these days, so this is good insurance. On the bike maybe half a cup every three or four months would be fine.
As I say been doing this for years with , out any problems. Enjoy.

Actually, doesnt do any thing to existing rust. removing the water helps prevent any rust forming/growing.

Yep- say no more.  Got it.  302.8 ml give or take a drop.

All of you!

I know this is an old thread, but if someone (no matter how unlikely) uses the search function it might help them.

When I was working for a fuel company, service stations would sell 300 mL bottles of iso propyl alcohol (C3H7OH) for dewatering petrol.  This has a high affinity with water and is very miscible with petrol.  It is also a heavier molecular weight molecule and less volatile than methanol so doesnt cause spluttering and misfiring.

Handy to know.

My lab used to use Iso for cleaning circuit boards after soldering.

Don't get it on your hands or skin as it dries out the oils. If you do, use a moisturizing lotion ASAP. It makes cracked heels look positively supple.

Ummmm . . So we now know roughly how much a glugg is but now we have another measure introduced which I am trying to gather in my mind the size thereof, no not my mind - that is miniscule, I’m talking about a drop . . The size of a drop . . I’m guessing smaller than a glugg . . But how small . . . Nothing much on Teev . .

Then you should be well aware that water is heavier than fuel and that all things being normal water can't get into a petrol tank. The pump pick up point is above where any water will be pumped however there is a chance water can be pumped if an underground tank has just been filled. Some tanker driver's would advise an operator to turn an empty pump back on while they were still filling; some might but I used to wait for the tank to settle for a while.

What also can happen is water tests may not have been carried out at a particular service station which is needed to be done so water can be removed by a third party. If this isn't carried out eventually the water level rises to where it shouldn't; not a normal situation.

When I was with Coles Express they installed automatic level and water detection equipment in each storage tank taking service station staff out of the equation.

Floods can cause water too.
